That old pine in particular is some crazy hard stuff. 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. Nitro V is also significantly cheaper than many other steels with this level of performance. However the 14c28n steel would be great for an EDC knife with typical usage. So the major tradeoff is in how much carbide you want in the steel for edge retention without dropping toughness too much for the intended knife and user. Many knife enthusiasts are concerned with categorizing steels as excellent, good, poor, etc. also the angle is by far the most important factor in catra testing, so such results might be irrelevant. Thanks to its very high hardness (64-66 HRc compared to the average of 58-62 HRc), ZDP-189 can be ground thinner and sharpened less often. But SM100 is not widely available, hard to heat treat and grind, and exceptionally expensive. Typically an increase in corrosion resistance means a reduction in potential hardness for a given steel. Give it a couple of weeks, and feedback will start pouring in. Its actually quite good, low-cost steel that performs like midprice steel. They were two different tests (different batch of steel, different person heat treating, etc). Steels do come at various price points, however, depending on the cost of producing them and the cost for the knife company to work with them. 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. Its called memory metal because heat can get it to revert back to a previous shape. -> Maybe prequenched 14c28n could be a little tougher than AEB-L? 14C28N Vs D2 . Rex 45 Some of our partners may process your data as a part of their legitimate business interest without asking for consent. The hardness level of steel is determined using a universal scale called the "Rockwell C Test", commonly called the Rockwell hardness scale (HRC). Its not a regression line, it is just a line through the best steels. In nitrogen steels, nitrogen is used as the iron-hardener instead of carbon, thus limiting the possibility of rusting. 14C28N is stainless steel, and its knives offer excellent rust resistance and toughness than D2 steel. It has an HRc over 70, usually even harder than Maxamet. We did the research to help you find the best hunting knife for your needs and budget. I also added a few more steels in this study. Not every element is shown in the charts. But in my experience, it has been nothing but great. https://cedric-ada-store.creator-spring.com/listing/brickard-heritage-collectionGood gravy its bricky on thingsSubscribe and hit the bell! It is among the steel knives with exceptional toughness while maintaining excellent corrosion resistance. Cool! If you are looking for a high-end knife on a budget, the varieties of both steel will serve you. This was not necessarily because of superior toughness but because of the superior strength of the MagnaCut from higher hardness. Moreover, the blades will serve you longer because they do not wear out faster with frequent use and sharpening. 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. The 14C28N stainless steel from Swedish manufacturer Sandvik is considered an upgrade to their 13C26 steel (described below). Did you change the estimate based on more testing? CROMOVA 14C28N Leek: D2 Leek: jonnymac44 Joined Sep 27, 2007 Messages 7,674 Oct 21, 2008 #2 Hey Michael, First off, the new 14C28N from Sandvik is just now hitting the streets, and I don't have any results just yet for you. 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. High wear resistance steels are more expensive to buy and to process, especially since many require powder metallurgy. 14C28N steel also has excellent wear resistance due to its high chromium content. That is professionaly popular such as the Japanese designation SKD11, Uddeholm Sverker 21, German designation 1.2379, Hitachi SLD and others. Vanax and LC200N are unique in reaching 59-60 Rc while being very stain resistant. most knives are being made out of these and other mediocre steels like 14c28n, 420j2, 425m. I have not provided a rating for ease in sharpening. High Alloy Tool Steel and High Speed Steel Ratings. You cant look at only the chromium content of the steel to know the level of corrosion resistance. Not every wood is soft pine. Cookie Notice There seem to be a lot of modern steels that get related to D2, but OTOH just saying a steel is similar to D2 seems to kill interest in it. However, even steel with the best corrosion resistance can rust without proper care. They tend to be relatively expensive and difficult to sharpen, as they have high wear resistance. there seems to be an optimal procedure for every alloy (provided its heat treated to industial standards). On the other hand, in d2 air-hardness steel, you cant differentially temper the blade-like other high carbon steel because the steel can also be challenging to sharpen. Stainless steels are another subset of high alloy tool steels that have enough chromium in them to have stainless levels of corrosion resistance. Are you okay with that? And Michael Fitzgerald, Tim Marais, and Head VI for increasing their contributions. Why do knives make the best gifts? LC200N has similar properties to those two but with saltwater levels of corrosion resistance. There is no such thing as a steel that is a 10 in both toughness and edge retention. Steel softens as tempering temperature increases, but certain steels see an increase in hardness in a certain higher temperature range such as shown below for high speed steels that are designed for this type of tempering: This high temperature tempering can be done for several reasons, such as better resistance to overheating during grinding, or because a coating will be applied to the knife that requires a high temperature. Everyone has their own opinion on what they deem the best folding EDC knife. 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. The steel loses some of the chromium in solution for corrosion resistance to form these fine carbides for hardness. For more information see our. Blue Super and 1.2562 have higher edge retention but relatively low toughness. However, Kershaw asked Sandvik to make their 13C26 steel more resistant to corrosion, and the result was 14C28N. D2 steel also offers similar toughness levels as the 14c28n steel, so both aren't really prone to chipping with proper use. Although it should be noted that there doesnt seem to be a need for the stainlessness on a wood working tool. Lots of information is still specific to this article, however. It shows 3 stainless steels from 750-800tcc but the edge retention graph only has 1 SS in that range, S90v. We should be suspicious of anyone who is claiming very high edge retention with a steel at low hardness and a small amount of carbide. Steels 7Cr and below arent worth your time or money. Or even a 7 in both categories. The knives can be used in humid and wet environments without rusting. A2 is a tool steel renowned for toughness. Around 61 Rc usually. Rex 121 23.5% vanadium carbide, 4% molybdenum/tungsten carbide (M6C), Conventional Ingot vs Powder Metallurgy Carbide Structure. SPY27 Poor availability may effectively increase cost of steel. . Steels that are higher in hardness and wear resistance are usually lower in toughness. Later, it gets heated and compressed into one ingot. 14C28N knives are easier to sharpen than D2 knives. Each steel was tested with a knife that was produced just for the test, and then sharpened the same way for each test (15 dps 400 grit CBN sharpening). The hardenable grade of titanium (Beta C Titanium) reaches up to 45 or so rc. 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. Thanks! False treatment and geometry upheld by Made in USA is like buying 8Cr from China (except late A.G) My personal experience tops with Vanadis 4E, CPM-M4, RWL-34 and the likes. I think they are complementary and you should watch/read both. By that I dont mean that a better heat treatment is not possible, but that major mistakes in heat treating are avoided. you can easily buy a $500 knive made out of 14c28n, which has nothing in it besides cr and a trace of ni. Here is the article by Larrin on 48 steels. An example of data being processed may be a unique identifier stored in a cookie. It would be interesting to try to develop a conversation between /geometry/edge retention/toughness, so we could say e.g. Though technically not a stainless steel at least 14% chromium, and D2 usually has 12% it's relatively corrosion-resistant. Both steel types don't chip easily, but 14c28n steel is easier to sharpen. Generally seen as a slight upgrade to the 440C/VG-10/ATS-34 caliber of steel, its a decent all-around steel with good corrosion resistance, decent toughness, and only modest hardness. If you would like to change your settings or withdraw consent at any time, the link to do so is in our privacy policy accessible from our home page.. Looks like there is no reason to us it over 420HC. This is good for ease in heat treating in large batches and for even cooling that greatly reduces warping and size changes. They differ little in composition and treatment. Its not a particularly great cutter, being poor at retaining an edge. While not a powder steel, 154CM is widely used in nicer knives. Some steel companies charge more than others. 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. For more information, please see our But which? Aluminum oxide is used in most common sharpening stones and it is softer than vanadium carbide, which makes sharpening high vanadium steels more difficult. High Alloy Tool Steels and High Speed Steels. 14C28N knife will dull faster, but it is easy to sharpen. The brand designed it as a carbide replacement. 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). I am particularly interested in researching knife steel, knife properties, and brands. The ESEE had significant edge damage while the MagnaCut knife did not. I will be focusing on CATRA edge retention which measures abrasive wear of knives. Sandvik 14C28N steel offers excellent corrosion resistance, exceptional toughness, good edge retention, and is easier to sharpen. This list is not exhaustive, so check out some of our rating tables for more information on whatever steel youre interested in. Corrosion on knife steels most usually takes the form of rust, patina, and staining. CPM154 is a truly superior steel. Using controlled furnace heat treating resulted in toughness around 23-28 ft-lbs at 61-62 Rc, while the knifemaker heat treated specimens were 7 ft-lbs or below. Edge retention often refers to the ability of a knifes edge to maintain its sharpness during use. When it comes to handle material, both knives have options available in either plastic or metal. These steels are the good old hard-working steels. worldwide, even the chinese have an equivalent (8cr13mov). This particular steel grade allows for the highest attainable hardness without. 8cr13mov if proper slicing geometry its good budget steel if you dont rust it and no prying or screwing its ok cutting steel. European steel company Sandvik produces 14C28N, a non-powder metallurgy steel. Check out theGiantMouse Vox/Anso ACE Iona Liner Lock Knife at $99, for example. S45VN In use, its very similar to 440C and VG-10. what does a cvn of 40 v.s 20 mean? For instance, if a 35 edge in 1095 steel at 58 Rc provides appropriate toughness for planing hardwood, what edge angle in, say, AEB-L at 62 Rc might give us a comparable effective toughness? Among Vancron SuperClean, Agomi #1 and Shirogami #1, Which one tends to have finer grain size and Sharper edge? What it is: D2 is a carbon tool steel with a relatively high chromium content, prompting some to call it a "semi-stainless" steel. Its tough, but thats about it. Corrosion is not only cosmetic. It's more often pitted against the VG10 since both are widely popular high-carbon stainless steel grades. I hope you will find value in the articles on this website. This is about comparing steels to each other rather than a limitation of an individual steel. The knives are ideal for both indoor and outdoor use. Thanks Larrin, Where did it come from? in relation to hardness). In my experience, it will tarnish and discolor quickly. (I think the 420HC estimate in that post was based on simulation or computer modeling, since you didnt spray testing any of the 400 series.) Generally this is code for difficulty in abrading away steel. This is a major tradeoff between improved cutting ability and edge retention with an acute angle vs a strong and chip resistant edge with an obtuse angle. VG 10 Steel, https://knifebasics.com/author/freelancer/, How To Choose Between The 14C28N And The D2, 14c28n Steel Is Good for Knife? But to learn more about these and other attributes, read our related outdoor knife buyers guide. 14C28N steel holds good hardness. Sharpening the knives might be challenging, but the D2 knife is high quality and affordable. However, it falls behind the Bohler steel in corrosion resistance. Its hard enough, tough enough, and stain-resistant enough. Only a few years ago Elmax was pricey, but competition has driven it down to reasonable levels, making it a decent value. I love reading through all the data youve gathered and making note of all the trends (Im a physical organic chemist). Stainless steels usually top out around 64 Rc and may require careful heat treating to get there. With a high level ofedge retention, corrosion resistance, and toughness, it does most everything quite well. Many custom makers enjoy AEB-L, as its easy to machine but still has a high hardness, around 62 HRc. The blackwashed D2 steel blade of the Kershaw Cannonball offers pretty good corrosion resistance for D2. And before you start arguing on behalf of the steel you think might be perfect, let me remind you that if your knife isnt perfect for a task, youll need to get another one that is! Jesse Jarosz, a custom maker from Montana, regularly uses AEB-L. I see very little about cryo outside of journal articles, and I wonder which knifemakers use it. Editors note: This article was first published in May 2015 and was most recently updated on May 25, 2020. in the correct place for the stainless-toughness-edge-retention graphic? The reason is because sharpening and edge geometry will also greatly control properties. The old rule in steels used to be corrosion resistance, toughness, or hardness choose two. But SM100 (the trade name for Nitinol 60) threw that out the window when introduced to the cutlery world. Theres a green triangle at about RC 60.5 and toughness over 40. M390 Also how did you arrive at the edge retention & toughness numbers for 8cr13mov and for BD1N toughness? So setting edge geometry for the type of knife and intended use is very important. Very much appreciate you. Available in Kershaw knives (as of 2012) and in other . Read more. Why do you give a coin with a knife as a gift? Hes already done a three part series on cryogenic treatment: This is a midprice steel with matching performance. 2. The Kershaw Leek is a most popular EDC knife that design by legendary custom knife maker Ken Onion. In that case the difficulty in sharpening would be the inverse of the edge retention rating. And while it can be hard depending on the heat treat, I have found it easily chips, causing microscopic dings in the edge when hardened to a high level on a thin blade.

If you look at the chart you may notice that at high toughness levels if you increase edge retention by only a relatively small amount you get very big drops in toughness. The big names in powder metallurgy are Crucible (CPM- steels), Carpenter (CTS- steels), Bohler Microclean (M390), and Uddeholm Superclean (Elmax, Vanax). Its not bad, but you can find better in the market at the same price. How could it be? 14c28n vs. D2 Steel D2 is as rigid as 14c28n, thus has almost equal edge retention abilities. I would also suggest adding a hardness rating to the ratings tables that currently include toughness, edge retention, and corrosion resistance ratings. D2 holds it for longer. Heat treatment refers to the heating and cooling steps employed to achieve your knifes proper balance of attributes. AEB-L and 14C28N are the best in the high toughness group. Toughness 3, Edge Ret 8, Cor Res 4? Steels with very high vanadium content like Vanadis 8, CPM-10V, K390, CPM-15V, etc. High wear resistance is not particularly necessary when only performing chopping, and its good ease in sharpening helps when having to restore the edges. 2. you can easily buy a $500 knive made out of 14c28n, which has nothing in it besides cr and a trace of ni. Several factors arent related to the steel you choose but seriously affect the nature of your knifes performance. 420 Simple, non-stainless steels of medium carbon content like 5160 also boast high toughness. We and our partners use cookies to Store and/or access information on a device. Edge retention is the ability of a knife to maintain cutting ability during cutting. Some of these steels also have vanadium (CruForgeV) or tungsten (Blue Super, V-Toku2, 1.2519) for increased wear resistance. So, its hard steel is easy to sharpen. CPM-S90V, CPM-S110V, CPM-10V, and Bohler K390 each fit in this category. However, Kershaw asked Sandvik to make their 13C26 steel more resistant to corrosion, and the result was 14C28N. This is the basis on which I do the ratings rather than a linear scale. Its an anomaly in the knife world and quite puzzling to use. High alloy tool steels are designed to be air hardening, so they can be cooled even slower than the oil hardening steels found above.
