It richly deserves its reputation for high-quality gained over the years by Sandvik, a Swedish manufacturer of world-renowned steel. Low Carbon steels like AEB-L wont hold up to wood cutting even though it can hit 64 hard, it just doesnt have enough Carbon. Combination of knife steel properties. I also added a few more steels in this study. The 8Cr13MoV vs D2 debate. 1) the cvn number is just that, a number. BD1 is excellent budget steel, very similar in composition and performance to GIN-1, a Japanese steel used a decade ago by Spyderco. Divers, sailors, and anglers need knives that will resist corrosion above all else. Or even if they try to be more open to importance of toughness, the good reputation of the high edge retention steels means that they get inflated toughness ratings along with it. The D2 steel compares nicely with 14c28n steel in terms of edge retention, as it's quite hard as well. However, Kershaw asked Sandvik to make their 13C26 steel more resistant to corrosion, and the result was 14C28N. 1095 stains easily and thus is often coated, especially in fixed blades. If you want for best steel 14c28n and others steel then you can ready 14c28n vs 420hc review. Corrosion is not just about cosmetics and rusting, however, but can also affect edge performance. I especially appreciate the geometry/edge retention/toughness comparison with photos. Steels with very high vanadium content like Vanadis 8, CPM-10V, K390, CPM-15V, etc. If you want a sharp knife for outdoor or indoor use, D2 knives will not disappoint you. Extra kudos for your mathmatical steel composition to edge holding model thats really impressive work. I like it in the Seki City Spydercos, but I would like to know what ratings you would give it. They are usually chosen for their looks rather than performance. Hi Larrin Youve occasionally mentioned cryo treatment in your posts, including here with LC200N. The best scenario is when the steel, heat treatment, and geometry are selected for the knife and the use. In all of the cases above, properties are greatly controlled by carbides. There are significant differences between them because 14C28N is stainless steel, while D2 steel is a semi-stainless tool steel. CPM-S90V is my favorite in the high edge retention category because of its decent toughness. I dipped each in lemon juice and left in open air and tested after 30, 100, and 300 minutes, dipping in lemon juice again each time. Manage Settings 14C28N VS Steel. Water is a severe quenchant that can often lead to warping or cracking. Must-Have Bowie Knives for Your Collection, What is Micarta and What Makes It a Great Knife Handle, Top 8 Reasons Why Knives Make the Best Gifts, Pocket Clips: Carry Safely and Comfortably, Make a Knife Your Own with Accessories & Customization. Any idea where it would be on the hardness and toughness scales? Instead, Vargo titanium uses a unique material called sintered titanium-ceramic alloy. Anthony Sculimbrene authors the blog EverydayCommentary.com. You said wood is not a particularly abrasive material and in absolute terms that is very true. That is an air-hardening- high carbon, high chromium tool steel. Its an update of its 12C27 and 13C26 steels, which were developed for use in shaving razors. The material increase machinability and strength. On the spreadsheet, youve grouped AUS-8 and 8Cr13MoV. Between the assisted open, weird looking texture designs, and the stainless steel handle, the Cannonball has a lot of features I don't normally like, but even I have to admit it's a good design for the price. I have a question about the chart One important concept I want to hammer home is that there isnt one property that is most important. just recently the idea occured tome to sharpen a planer blade like a knife and check out how it performs. Most steels use carbon to increase hardness, but 14C28N uses nitrogen, boosting hardness without the normal penalty of increased corrosion. Thanks. drop point Flashlights run the gamut of price and quality. 440A They tend to be relatively expensive and difficult to sharpen, as they have high wear resistance. Jesse Jarosz, a custom maker from Montana, regularly uses AEB-L. It is among the best steel that will offer exceptional toughness while still maintaining excellent corrosion resistance. The following are less common steels, but theyre definitely worth tracking down. My test is for comparing different steels, not necessarily for a go/no go test for saltwater applications. I think you wrote an article a bit ago on CTS-XHP and concluded that like D2 and ZDP-189 it wasnt really stainless (although stainless is a somewhat arbitrary line). Poor availability may effectively increase cost of steel. . However, many kinds of wood are REALLY tough and very hard on blades. This is an American-made powder steel produced by Crucible and developed specifically for knives with the aid of the knife guru Chris Reeve (maker of the vaunted Sebenza, among other gems). H1 It is an excellent steel that in the right hands has proven to produce high performing blades. So youre right that a D2 blade will cut more CATRA cards than an AEB-L blade *when theyre both sharpened to the same angle* but AEB-L has much better toughness and can therefore handle being sharpened to a more acute angle without chipping, and a more acute angle is more important to continuing cutting ability than wear resistance is. I guess that was before I started reading. I have an article that lists off the major mistakes often made in heat treating. In general, higher carbon steels have higher edge retention but lower toughness. 12C27 The knives can be used in humid and wet environments without rusting. most knives are being made out of these and other mediocre steels like 14c28n, 420j2, 425m. Is this at the same hardness? Because of its abrasion-eating hardness, knives with REX 121 come at an exceptionally high price. In its most basic form, steel is just iron and carbon, but people have been studying, experimenting with, and perfecting steel with other elements for specific applications for millennia. GearJunkie Copyright 2013 2023. I havent tested Sleipner yet. Toughness and edge retention are generally opposing properties and it is difficult to improve both of them at the same time. Toughness 3, Edge Ret 8, Cor Res 4? 2. The knife Natrix with substantial copper handle is a deceptively hefty EDC. Did you change the estimate based on more testing? As a result, there are no production knives with REX 121 steel, though Ferrum Forge used the steel early on in its custom knives and a Kickstarter knife from the Creely Brothers. In fact, its not technically a steel at all, as it uses titanium and nickel. LC200N is produced with a special technique to add high nitrogen, giving steel excellent corrosion resistance on the top! (Some crazy folks clean their Swiss Army knivesin adishwasher. Low Carbon steels like AEB-L wont hold up to wood cutting even though it can hit 64 hard, it just doesnt have enough Carbon.. Some steels are more difficult to manufacture for the steel company or have more expensive alloying elements so the cost is increased. However, high wear resistance means that abrasives are used up more rapidly, more careful grinding is necessary to avoid overheating, finishing and polishing is much more time consuming, etc. It also tops out around 60-61 Rc like LC200N and needs relatively careful heat treating to even be that hard. 1095 Old time 8670, 5160 (known to ignoramuses as 51shitty) and 52100 are excellent choices and arguably better choices than 80crv2. We can predict edge retention of a steel within a relatively narrow band based on hardness and carbide volume. Read more. its like with cars, most of them are not a corvette or a porsche. Around 61 Rc usually. In a pocket knife the total amount of steel is rather small. The vivid patterns visible in Damascus steel come from the acid etching process in a ferric chloride solution. rex 121 D2 knives offer higher edge retention than 14C28N knives, which is attributed to the high carbon elements and hardness of D2. Is there a reason SG2/R2 are not included in the lineup, despite being one of the most popular ones? 0.62% of Carbon: Makes knives harder and more resistant. 440B Crucible intends SPY27 to be good all-around knife steel. However, it can be somewhat complicated because an edge can dull from many causes wear, micro-chipping, deformation, or corrosion. In thick forms, like a fixed blade, 1095 isa tough, low-cost steel. D2 has been around for more than 20 years, an eternity in metallurgy terms. It improves wear resistance and hardenability. AEB-L is a non-powder steel produced by Swedish steelmaker Uddeholm. 14c28n is the most popular material for the knife: stainless steel and made by the Swedish company. Non-stainless steels can be heat treated to 66 Rc or even higher depending on the particular steel. 14c28n steel and D2 steel are both high-quality knife steels. MagnaCut has the lowest chromium of any of the below steels but all of its chromium is in solution (no chromium carbide) and the fact that it has no chromium carbide also gives it the maximum level of corrosion resistance for a given amount of chromium. Many steel ratings seem to over-emphasize edge retention. and our The excellent corrosion resistance properties of 14C28N are attributed to the high amounts of chromium in its composition. Also I notice 1095 looks like another underperformer as there doesnt look to be any reason to use it over 5160 which I cant imagine is any more expensive than 1095. Would be great if some manufactures changed their steels based on this information. 14C28N steel is known to offer among the best if not the best toughness in knife steels out there. 12C27 steel is extremely popular in the US knife market for its high hardness, high wear resistance, and great corrosion resistance. Maxamet and Rex 121 are so extreme in terms of wear resistance and edge retention that I rated them higher than 10 because otherwise it throws off the ratings for everything else. This was not necessarily because of superior toughness but because of the superior strength of the MagnaCut from higher hardness. Anyway, buff up the O1v and it cuts leather easily. With toughness it is a bit harder to link to only one article as I dont really have a summary of all of the toughness testing that we have done. Note:There is a powder-metal version called CPM154 thats purer than the non-powder version, making it easier for knifemakers to grind. Hammering through hickory, digging at roots in sandy soil, and cutting around bone did nothing to chip, dent, or roll the edge of my 3V knives. The bump in hardness comes from precipitation of fine carbides in the steel, which include chromium carbides. 14C28N vs. D2. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. Thank you for such a great article! In addition, According to Sandvik, 14C28N steel is easy to work on, reducing production costs and hence affordable knives. Quite an eyeopener! This is one of the better steels on the market. Unfortunately a high amount of it decreases strength. You do not expect the prices to be as low as those of low-end knives, but you will get high performance at affordable prices with either. It can withstand a lot of wear and tear. In many cases, the D2 edge sharpness may last a bit longer. I actually dont recommend that enthusiasts spend all that much time analyzing the exact composition of different steels and trying to guess their properties. If the steel is overheated in austenitizing, very large reductions in toughness are possible. One such person is Dr. Larrin Thomas, a professional metallurgist raised by a knife maker and a giant knife nerd. D2 steel, on the other hand, is tool steel, and its knives shine on edge retention and wear resistance. Low Alloy tool steels have small alloy additions to increase hardenability so they harden more easily in oil rather than water. When it comes to handle material, both knives have options available in either plastic or metal. But Ive found it lacking in hardness, even when compared to cheaper steels like AUS-8. It mainly made for knife and it high in Chromium for excellent corrosion resistance. This is a nitrogen steel that is extremely corrosion-resistant so much so that its used in knives designed to go in salt water, among the most difficult conditions knives are used in. So you can estimate how much a change in hardness would affect edge retention by following the slope of those lines. I love reading through all the data youve gathered and making note of all the trends (Im a physical organic chemist). Therefore, you cannot purchase the knife for use in corrosive environments. D2 steel is more durable than 14C28N, but it scores lower in terms of ease of sharpening and corrosion resistance. For example, see the chart below for how much edge retention can change with edge geometry for a single steel (in this case 154CM and CPM-154). A2 Knife Steel Air-hardened tool steel. Moreover, the blades will serve you longer because they do not wear out faster with frequent use and sharpening. Sorry, most of my previous comment was borderline word salad. Actually, Id be thinking 14C28N, but I want to leave stainless out. 14c28n vs. AUS-8 Steel The best knife for you should meet your needs and fit your budget. Below shows pictures of a 61 Rc knife that was impacted with a 3/16 rod at different energy levels. It mainly made for knife and it high in Chromium for excellent corrosion resistance. But in my experience, it has been nothing but great. 1. The steel falls under the Sandvik series of steels and makes one of the 7 steel grades in this family including 12C27M, 14C28N, 13C26, and others. High Alloy Tool Steels and High Speed Steels. AEB-L and 14C28N are the best in the high toughness group. If you are a newbie, sharpening D2 knives will be a struggle, but it is doable with practice and the right sharpening tools. If thats true why do you include it in the stainless steel category? [Complete Steel Guide], What is Vg-10 steel?- [Steel Knife Review], The Difference Between 440c steel vs d2: Compared guide, Is 8cr13mov Good Knife Steel [Complete Steel Guide], Amazon Best Sellers in Pocket Knives & Folding Knives. Get for a complete guide about other steel; you can read 14c28n vs 8cr13mov reviews. I was recommended the Rat 1 in D2 and I also found that I really like the design of the Ruike p135 and p128. And given the recipe, it has a low number of carbides, the extra-hard microcrystals in steel that provide the hardness necessary for a stable and sharp edge. Its hard to imagine a more rust-inducing environment than saltwater and fish guts. I couldnt find much on 5160 steel and from a knife makers point of view if you are saying youre the preferred supplier of special ops than I dont understand this choice in knife steel. As of November 2020, this is Spyderco-exclusive steel. https://knifesteelnerds.com/2018/12/17/cryogenic-processing-of-steel-part-3/. The big difference in properties vs the low alloy steels, however, are the harder carbides that are found in these steels. Here, youll learn the different factors that go into each steel, ratings for a wide variety of steel alloys, and youll get some recommendations for types of knives different types of steel work well for. This means consumers should be able to maintain these quality knives at home. I believe they are made of simple carbon steel. Where did it come from? Spyderco offers this as the high-end steel for many of its evergreen blades, like the Paramilitary 2, Paramilitary 3, Manix 2, and Native 5. Because of their good edge retention, these steels are quite versatile in folders and fixed blades. Also many hardwoods will dull planer blades just because theyre more dense. Softer steel usually forms larger burrs and they are more difficult to deburr. This guide explains important features to consider when buying a new knife for the outdoors. As with high alloy tool steels, the amount of vanadium can be a shortcut to predicting the general level of wear resistance and edge retention. -> Maybe prequenched 14c28n could be a little tougher than AEB-L? Poor heat treatment can make a knife too hard, too soft, hard to sharpen, easy to deform, or cause other issues. This showed that XHP and ZDP-189 have significantly lower corrosion resistance than other stainless steels. There is buzz out there but I havent seen anything solid yet in the world of steel. D2 knives, on the other hand, are challenging to sharpen. we dont know. You showed some pictures in this article of the effect on what we might call "effective toughness" of thinner edge angles vs thicker edges in the same steel at the same hardness. A quick check shows the compositions of these steels are nearly identical, so based on that Id expect them to perform similarly (differences in heat treat and blade geometry aside). https://i0.wp.com/knifesteelnerds.com/wp-content/uploads/2021/10/stainless-toughness-10-19-21.jpg?w=757&ssl=1 The main downside is the steel is more difficult to heat treat and can't go harder than about 60 or perhaps 61 Rc. You can see that 64 Rc AEB-L has both lower toughness and edge retention than 61 Rc MagnaCut, so I feel that in general you get a better sense of where the steels fit with a single point. Cool! If the properties of a knife meet your knife needs and it has the above characteristics, then it qualifies as a quality knife. You also reported 8.6 for 440A in that post, compared to 8.5 in this post. Often used for combat knives. 14C28N VS D2 The two sheets of steel are comparable in terms of toughness and corrosion resistance. Tanto 8670 and 5160 are good choices for large knives that need very high toughness. This is about comparing steels to each other rather than a limitation of an individual steel. Alloying elements are an important ingredient vital in getting the best steel for the job. Hi Jimmie, thanks for your comments. Typically an increase in corrosion resistance means a reduction in potential hardness for a given steel. Here, read on for an in-depth look at common knife steels as well as the best knife steels around. Liquid steel is sprayed through a tiny nozzle, solidifying into a powder. 1095. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. D2 steel also offers similar toughness levels as the 14c28n steel, so both aren't really prone to chipping with proper use. Steels without these attributes are much less costly. 14C28N and D2 steel are not the same. The highest edge retention steel was Rex 121 which was at 70 Rc in combination with lots of high hardness vanadium carbides. European steel company Sandvik produces 14C28N, a non-powder metallurgy steel. This is a powder steel produced by American steel company Carpenter. Both steel types don't chip easily, but 14c28n steel is easier to sharpen. The big names in powder metallurgy are Crucible (CPM- steels), Carpenter (CTS- steels), Bohler Microclean (M390), and Uddeholm Superclean (Elmax, Vanax). [Steel Knife Review], Best survival knife sword: 5160 steel Review, What is VG 10 pocket knife? Hi there, . Most of these steels are carbon steels, except for CPM MagnaCut (the fancy steel cooked up specifically for knives by Dr. Thomas), which has excellent corrosion resistance. Metallurgy and Testing of Knives and Steel. VG 10 Steel, https://knifebasics.com/author/freelancer/, How To Choose Between The 14C28N And The D2, 14c28n Steel Is Good for Knife? A mirror finish is the best at resisting corrosion and a rough finish means rust and corrosion is more likely. D2 steel does not contain enough chromium to make it stainless steel. Having 1.5% Carbon does that. the more complex fracture toughness at least lets you make some estimates in this sence. then you have zirconia and diamond coated blades. 14C28N knives offer better toughness than D2 knives. Thats a little too far, but you get the point.). what does a cvn of 40 v.s 20 mean? But unlike most high-end steels, SPY27 is an easily user-serviceable powder steel. But I think it would have much higher toughness than any of the steels on the chart. Its a costly and challenging process, but it makes extremely fine-grained steels, some of the best for knives, and makes some processes that were previously impossible a reality. A new steel from Crucible, SPY27 launched in 2020 in the Spyderco Native 5and Para 3. Being stainless is not an on or off property, and some stainless steels are more resistant to corrosion than others. Powder metallurgy steels with low vanadium content like CPM-1V and Z-Tuff/CD#1 have extremely high toughness. Not as tough as the best carbon steels, it's tougher than most . Its called memory metal because heat can get it to revert back to a previous shape. LC200N has similar properties to those two but with saltwater levels of corrosion resistance. It was originally developed for use as ball-bearing steel by NASA. third and most important is what happened to the burr. So for most steels they are given a rating at around 59-62 Rc, apart from a few steels that are never used at that hardness. https://knifesteelnerds.com/2018/12/03/cryogenic-part1/ Some steel companies charge more than others. Im not hating on 80crv2 , Ive used it. 14c28n steel has a high Chromium and Carbon percentage. Its so high in hardness that Maxamet knives usually ship with desiccating packages. These steels are perfect for thin edges and high hardness. Theyre excellent for choppers, hard-use folders, and outdoor knives that see impacts and heavy use when used at medium hardness. 9Cr is the top end of the series and is quite good as good or better than AUS-8. It doesnt hold an edge well, but its so easy to sharpen that you can get it back to razor sharpness in a few minutes. It is most useful for steels with large amounts of carbide but also helps to be able to add certain carbide types. The very good toughness of MagnaCut meant that it didnt chip despite this relatively high hardness and the difficulty of the test. How do its properties compare to other steels? By signing up for email newsletters, you agree to GearJunkie's, Click to share on Facebook (Opens in new window), Click to share on Twitter (Opens in new window), Click to email a link to a friend (Opens in new window). Im not sure they answer my question, though, and some of your points dont seem to jive with the info here on Larrins site. Or even a 7 in both categories. The only thing putting me off immediately buying the p135 is the 14c28n steel. The difference in properties between 14C28N and D2 steel is very clear. Most of the midrage ifferings have 14c28n, how does it compare to d2 in your experience? These steels are typically used by forging bladesmiths, traditional folders, and some production fixed blades. Developed by New Jersey Steel Baron, Nitro V is a non-powder steel marketed as an enhanced version of AEB-L. Nitro V, as its name indicates, adds nitrogen to AEB-Ls formula to make the steel even more corrosion-resistant. You will get an ultra-sharp edge with 14C28N knives. Is Vancron SuperClean a good choice for a chef knife? rust resistance.Best of all most knives made from this steel can be had for well under $75.In my opinion Sandvik 14c28n is a better overall steel than that of Aus8,420hc,or ANY of the . CPM 3V . I like it. There one of the best reason that he is highly regarded as a knife designer. This is a powder-metal steel also produced by Crucible. Many custom makers enjoy AEB-L, as its easy to machine but still has a high hardness, around 62 HRc. Spyderco and Cold Steel have used it, though Cold Steel recently switched to S35VN due to availability concerns. I was thinking maybe Sleipner or A2 would be best if a PM steel was out. Let's compare 14c28n steel with other steels, and for this, I use four criteria; Edge Retention, Corrosion resistance, Ease of Sharpness, and Toughness and on a scale of 1-10 (10 being the highest) let's see the performance of each steel. H2 And easy to sharpen in our experience; and that will get an excellent razor edge that lasts for a reasonable price of time. Advantages: Toughness, edge retention. Below shows a comparison of carbide structure between D2 and CPM-D2, and then toughness measurements between the conventional and PM versions of CruWear, D2, and 154CM. SG2 A cryo treatment and close temperature control is necessary to achieve those hardness levels. The study of steel is now so complex and nuanced that one can acquire a graduate degree in the subject and still learn new things every day. Then we could say, e.g. There is a powder form, CPM-D2, and PSF27 is also very chemically similar. Thanks! Is that accurate? Or, is this perhaps a historically useful practice that made sense on softer/less tough steels, but would make less sense on some newer steels that can be used at higher hardness and thus higher edge stability? Since the heat treatment is done before you get your knife, and its impossible to tell how good the heat treatment is with your eye, you often must rely on the manufacturers reputation for a good heat treat. The steel is an air-hardness tool steel that is considered semi-stainless because of its high chromium content. Vanax and LC200N are unique in reaching 59-60 Rc while being very stain resistant. However, Kershaw asked Sandvik to make their 13C26 steel more resistant to corrosion, and the result was 14C28N. This isnt exactly how steel works; different properties are difficult to increase without affecting something else. When describing the characteristics of a steel, a few common attributes are commonly talked about. The steel is similar to Sandviks 13C26. Each of these contributes to a knifes overall performance. I will be focusing on CATRA edge retention which measures abrasive wear of knives. Distilled water can separate steels that are stainless vs those that are not. So, it is quite harder than most other steel variants and retains its edge sharp for a long period. After the steel is quenched it is reheated to a lower temperature to increase toughness and decrease hardness. All of the experiments shown below are possible thanks to supporters. Read more. However, to choose the best knife for you must consider all the properties, including toughness, edge retention, corrosion resistance, and ease of sharpening. You can read about my CATRA edge retention testing in this article. 1. Question. So what is the best steel for knives? This is an old high-carbon (non-stainless) steel. You cannot leave your 14C28N knives in water overnight and expect them not to rust. you can easily buy a $500 knive made out of 14c28n, which has nothing in it besides cr and a trace of ni. So presumably, wear resistance would be in the 3.5-4 range and toughness in the 5.5-6 range. However, there are other factors. That provides 14% Chromium and offers excellent corrosion resistance. Recommendations are welcome, If you are cutting against metal I would maybe try K390 in a Spyderco or an S110V knife if you need stainless. While some are into that type of thing, if youre familiar with a specific steel and want to compare it with another, you should definitely click on that button below. That mixture has one goal in mind: making a great steel for people worried about rust and corrosion. Like S90V, its a high-hardness steel, but its more balanced than S90V. D2 seems to run at high hrc. Wusthof Classic Ikon 8-Inch Cooks Knife Review, Victorinox Fibrox Straight Edge Chefs Knife Review, What is Cts bd1 steel? For this perfect size that for most tasks and the slim tip allows the knife to excel at piercing and detail work. Cronidur 30 https://knifesteelnerds.com/2020/05/01/testing-the-edge-retention-of-48-knife-steels/, Unfortunately it all comes down to marketing on everybody involved: Industry, knifemakers, users. Though technically not a stainless steel due to its composition, in use it performs exactly like one. show very different and even inversed behaviour (e.g. However, even in this case there is the complicating factor of carbide and abrasive hardness. Diving into the pool of knife personalization possibilities is a fantastic way to fend off the post-knife-buy blues. Below shows the results of MagnaCut testing vs other steels where it is labeled as New Steel.. I have a bachelor's degree in Mechanical engineering with a specialization in material science. These steels have sufficient toughness to handle thinner edge geometry. All rights reserved. And Michael Fitzgerald, Tim Marais, and Head VI for increasing their contributions. s30v 14C28N and D2 steel are not the same. looking at getting a nice larger flipper for a little under 100 AUD.
