Not impractical fantasy knives, but these two knives that have a col look to them. Toughness and edge retention are generally opposing properties and it is difficult to improve both of them at the same time. You can read an article I wrote on budget steels here. Thanks again for everything you're doing, it's a tremendous resource. 14C28N vs D2: Overview 14C28N steel is a high-end stainless steel created by the Swedish company Sandvik. You said wood is not a particularly abrasive material and in absolute terms that is very true. It boasts an incredible ability to continue cutting long after it seems dull. And its not made of steel. Rather than upgrade from D2 to M4 or S30V just drop the angle from 40 degrees to 30 degrees. This is an American-made powder steel. Below I have shown the difference in carbide volume between AEB-L, CPM-10V, and Rex 121 to get an idea of how much more carbide there is in the high edge retention steels. To reiterate the clearer part, I wonder if toughness increases faster than edge retention decreases as an edge gets thicker. 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 is a powder steel produced by American steel company Carpenter. And below shows a chart of carbide hardness, the equation we created to predict edge retention based on edge angle, hardness, and carbide volumes, and then the chart showing the good correlation: TCC (mm) = -157 + 15.8*Hardness (Rc) 17.8*EdgeAngle() + 11.2*CrC(%) + 14.6*CrVC(%) + 26.2*MC(%) + 9.5*M6C(%) + 20.9*MN(%) + 19.4*CrN(%). Using 10 dps sharpening (20 degrees inclusive on the chart) leads to about 5x the edge retention of 25 dps. my understanding is that wood is not a particularly abrasive material and a plane is more of a push cut action than a slicing action so I would have though edge stability and sharpness is more important than edge retention meaning ABE-L should work pretty well. Carbon steels are those that have primarily carbon added to them with some Mn or Si as well. Here, we will discuss edge retention, toughness, ease of sharpening, and corrosion resistance. The main downside is the steel is more difficult to heat treat and cant go harder than about 60 or perhaps 61 Rc. Socould you please clarify which steel is the outlier and which is the line>. Now that we know what each factor represents, we can see how the steels rank against one another. I wrote an article about knife steel ratings available online in 2018, where I concluded that none of them were very good. As wear resistance is increased the differences between conventional and powder metallurgy steels become greater. and yet millons of knives are being made out of 1.4116 (aisi 420mov?) If you want to learn more than keep reading past the ratings. and corrosion resistance than the 420HC steel. Here, we break down how to choose a flashlight, including best flashlight LEDs, batteries, designs, and more. On the other hand, edge stability in terms of micro chipping and edge folding is also good. And easy to sharpen in our experience; and that will get an excellent razor edge that lasts for a reasonable price of time. 9cr18mov vs 14c28n. Your email address will not be published. These steels offer a great balance of characteristics that work well, from big choppers to thin slicers. 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. These steels are best for knives that dont see impacts and are some of the most difficult to sharpen. CTS-204P and CPM-20CV are nearly identical steels made by other manufacturers. All three of these steels havechromium, molybdenum, vanadium, and tungsten components and will perform well in myriad tasks. Thanks Larrin, There are a lot of different types of steel out there . D2 seems to run at high hrc. Note just because a blade is made from the premium or high-end steels listed above does not automatically mean its better than the lesser steels. Therefore powder metallurgy is not necessary for certain steels, or could even be slightly detrimental. The ESEE had significant edge damage while the MagnaCut knife did not. Advantages: Toughness, edge retention. 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. This is about comparing steels to each other rather than a limitation of an individual steel. The biggest factor for cost of knife steel is whether it is produced with conventional ingot technology or powder metallurgy. It should get an ultra-sharp edge for easy cutting, hold the edge for long for easy maintenance, and have a sturdy and ergonomic handle for comfort and to prevent accidents. I know it's much more stainless and corrosion resisitance, but what about wear resistance? Dr. Thomas is a friend of ours here at Blade HQ, and with his help, weve worked to create this knife steel guide. Let the job at hand be your guide. If you shop for knives based strictly on steel, you might be disappointed. European steel company Sandvik produces 14C28N, a non-powder metallurgy steel. In general, steels look worse as you go up in hardness because the toughness is reduced by more than the edge retention is increased. You can see micrographs of different knife steels to compare their carbides in this article. When we plot toughness vs edge retention on a log scale instead we get a straight line that is a better visualization of toughness differences. For more information see our. The pictures below show the microstructures of the three classes of stainless steel on the market. Its a good balance between all three attributes, being relatively hard, tough, and corrosion-resistant. Combination of knife steel properties. imo o lot depends on how the blade is sharpened. 52100 and CruForgeV are good for general purpose knives. See the chart below showing 52100 steel that was overaustenitized (unintentionally) by a knifemaker that sent me specimens for toughness testing. LC200N has similar properties to those two but with saltwater levels of corrosion resistance. Steels with very high vanadium content like Vanadis 8, CPM-10V, K390, CPM-15V, etc. 9Cr is the top end of the series and is quite good as good or better than AUS-8. YMMV If I made some plane irons from AEB-L at 63 Rc (where its still tougher than 1095 at 59-60 Rc, the standard vintage steel in plane irons), could I drop my sharpening angle from 30-35 to 25? AEB-L is rarely found on production knives but can be found on custom knives easily. GearJunkie Copyright 2013 2023. (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.) Give it a couple of weeks, and feedback will start pouring in. These steels have sufficient toughness to handle thinner edge geometry. It has a lower hardness and edge retention as compared to the 9Cr knife. Some of these steels also have vanadium (CruForgeV) or tungsten (Blue Super, V-Toku2, 1.2519) for increased wear resistance. 14C28N The knives can be used in humid and wet environments without rusting. [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. 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. 14C28N steel is not very hard steel which makes it easier to sharpen. In general, higher carbon steels have higher edge retention but lower toughness. For example, Bohler M390, CTS-204P, and CPM-20CV are all nearly identical and indistinguishable in practice. You cant look at only the chromium content of the steel to know the level of corrosion resistance. That way you can get into the steel ratings quickly. Almost all of the knives in my EDC rotation are Spydercos, in exotic steels. The 10V specimens tempered at 1000F were 4-5 ft-lbs while the specimens tempered at 4-500F were 7-8 ft-lbs. Theyll be fully attributed to you with website and Patreon links, obviously. The steel is susceptible to overheating during hardening do not overheat. third and most important is what happened to the burr. Sandvik 14C28N steel is better than D2 steel in corrosion resistance and toughness. The consent submitted will only be used for data processing originating from this website. W-2 Knife Steel Benefiting from 0.2 percent vanadium content, W-2 holds an edge well and is reasonably tough. 0.62% of Carbon: Makes knives harder and more resistant. I can also say from personal experience that marine grade plywood will chaw up your saw blade and battery a lot quicker than standard plywood, but that probably says more about the glue that was used than the wood. Is there some way we might predict the relative "effective toughness" of different steels at different hardness and at different edge angles? Im a layman trying to understand what makes the best steel for my use. However, Kershaw asked Sandvik to make their 13C26 steel more resistant to corrosion, and the result was 14C28N. One important concept I want to hammer home is that there isnt one property that is most important. If you're stuck between 14C28N and 440C, here's a breakdown of the pros and cons of each type of steel. the following is not a critique, just a few thoughts to maybe put the relationships into a wider perspective and point to additional dimensions. 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. CN Vs VG-10 The Japanese steel, VG10 offers slightly higher edge retention but has the same level of hardness as 14C28N. Do honing steels as used on kitchen knives actually do anything useful? Metallurgy and Testing of Knives and Steel. Note that corrosion is detrimental for the cutting edge. SG2 14c28n is the most popular material for the knife: stainless steel and made by the Swedish company. This is to keep the focus on the elements that are making the biggest difference. I would think that the label applies to either the line or the outlier, but probably not both unless the outlier is a measurement error. Unfortunately a high amount of it decreases strength. I hope you will find value in the articles on this website. Most low alloy tool steels and carbon steels also have fine carbide structures without powder metallurgy processing. Poor availability may effectively increase cost of steel. 1095 stains easily and thus is often coated, especially in fixed blades. Steels 7Cr and below arent worth your time or money. I also added a few more steels in this study. The highest edge retention steel was Rex 121 which was at 70 Rc in combination with lots of high hardness vanadium carbides. 14C28N knives are better than D2 knives in corrosion resistance. Its so high in hardness that Maxamet knives usually ship with desiccating packages. Choose a factor below to start sorting. 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.. I believe they are made of simple carbon steel. 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. CPM-S90V, CPM-S110V, CPM-10V, and Bohler K390 each fit in this category. The Sandvik 14c28n steel is ideal for the manufacturing of steel knife blades. does 1.4116 deserve the title of title of ultimate trash steel? But in my experience, it has been nothing but great. 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. Ive found S35VN less chippy even at the same hardness. Spyderco has produced several production knives with Maxamet, and the steel debuted on the ZT0888. This is a virtually stain-proof steel suitable for all sorts of aquatic environments. 14C28N steel, also known as Sandvik 14C28N, is stainless steel made by Sandvik, a European steel company in Sweden. 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. D2 has been around for more than 20 years, an eternity in. Most of the discussion of how the ratings were generated, various caveats and details, etc. CPM-S90V is my favorite in the high edge retention category because of its decent toughness. This grade can be treated cryogenically to improve edge retention. And a label: AEB-L. The chart below has dotted lines which indicate the average effect of hardness for any given steel. H2 Powder metallurgy steels with low vanadium content like CPM-1V and Z-Tuff/CD#1 have extremely high toughness. Low Alloy tool steels have small alloy additions to increase hardenability so they harden more easily in oil rather than water. As a side note, pure tungsten carbide blades (from brands like Sandrin) can have very high levels of edge retention, but they are not made of steel. You can read about my CATRA edge retention testing in this article. 14C28N knives are easier to sharpen than D2 knives. In real life, would you expect any presumed increase in deviation from the specified formula, as well as the effects of said deviation, to negatively impact the performance of 8Cr13MoV to any truly noticeable degree? AEB-L is a non-powder steel produced by Swedish steelmaker Uddeholm.
