It does have chromium but is not as sufficient as required to be a type of stainless steel. There has been some internet controversy over the grinding and heat treat of this steel. 14C28N is a stainless steel that was developed specifically for use in knives. I have a few examples below for steels that I have ranges of hardness tested for both toughness and edge retention. Its hard to say. Anybody know how the Sandvik stacks up against all these other steels. You cannot leave your 14C28N knives in water overnight and expect them not to rust. A hunting knife has a singlepurpose: processing meat after akill. https://knifesteelnerds.com/2018/12/03/cryogenic-part1/ AEB-L Even metallurgists can have a difficult time estimating properties just based on the elements. I do not have rust issues with it (as long as I have a good finish) some heavy stonewashed finishes rust easier. And easy to sharpen in our experience; and that will get an excellent razor edge that lasts for a reasonable price of time. and yet millons of knives are being made out of 1.4116 (aisi 420mov?) W-2 Knife Steel Benefiting from 0.2 percent vanadium content, W-2 holds an edge well and is reasonably tough. AEB-L and 14C28N also have moderate edge retention though of course much lower than vanadium-alloyed powder metallurgy steels like S30V or M390. 14C28N steel is known to offer the highest toughness levels out there. How could it be? Steel produced in China is generally less expensive. On the other hand, 9cr18mov has a slightly higher molybdenum content which gives it higher hardness from quenching and helps drive carbide formation. Its very tough and exceptionally corrosion-resistant. It would be really useful to have the raw data that backs the charts that you produce. Honestly, yes, because its perfect steel for your knife, besides it depends on which knife, so when youre talking about chef knives, then 14c28n would be an ideal pick thanks to professional corrosion resistance and edge retention. They made planer blades out D2 for its edge retention. By that I dont mean that a better heat treatment is not possible, but that major mistakes in heat treating are avoided. There is no such thing as a steel that is a 10 in both toughness and edge retention. However, the 14c28n provides perfect edge retention with a maximum hardness of 62Hrc and the mixture of Chromium and Carbon. Even premium steels can have poor performance with poor heat treatment. 7:00am-5:00pm, 10am-7pm Tuesday - Friday This is a very important factor when selecting a steel for your knife blade, especially if you plan on spending a lot of time outdoors in an area with high humidity.. S30v is a higher ranked steel and considered a true Stainless Steel, with a 14% . Where the black-finished 1.4116 version has a simple, full flat grind, the D2 version has a compound flat grind that ends halfway up the blade's height. Blue Super and 1.2562 have higher edge retention but relatively low toughness. This refers to the angle of your edge and the thickness of the knife behind the edge. In general, steels look worse as you go up in hardness because the toughness is reduced by more than the edge retention is increased. The ESEE had significant edge damage while the MagnaCut knife did not. Edge retention is the ability of a knife to maintain cutting ability during cutting. For example, the Si space is blank for several of the carbon steels because they have a relatively wide acceptable range, not because the element isnt added. CPM 10V Is Vancron SuperClean a good choice for a chef knife? The most traditional models of pocket knives have different parts, such as the handle and cutting performance. This is basically a retrofit of a very old steel, adding more carbon to the recipe of 420 (hence the HC for high carbon). Working closely with our factory the heat treating of this steel has been perfected resulting in excellent performance for the price. These steels favor edge retention over all else. Heres The Best Review For You (2021), D2 knife blade offers high edge retention, Dulls faster, Requires frequent sharpening. Sorry, most of my previous comment was borderline word salad. In some previous articles I have shown the balance between my toughness and edge retention measurements such as in the following chart, where the high alloy non-stainless are in orange and the blue are stainless: However, one issue with these charts are that difference in toughness is that a linear scale for toughness is a bit misleading for visualizing practical toughness differences. 1. Steels that are improperly heat treated have excess retained austenite which makes them extremely difficult to deburr. This grade can be treated cryogenically to improve edge retention. 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. The hardness of the carbides does not matter much unlike with edge retention. 3) catra is (as far as i know) the only accredited (iso/en) testing method. I would love to see a Tungsten-Carbide blade (like Sandrin is using) and how it compares for Edge Retention, Toughness and Corrosion Resistance especially how it compares to s90v. 14c28n is the most popular material for the knife: stainless steel and made by the Swedish company. Steels like CPM MagnaCut, CPM M4, CPM 4V, and CPM CruWear fit in this category. Marco, BSc Chem. But to learn more about these and other attributes, read our related outdoor knife buyers guide. Ive found S35VN less chippy even at the same hardness. This is a virtually stain-proof steel suitable for all sorts of aquatic environments. And we list budget-friendly knives that have a professional style and grace to them. Spyderco and Cold Steel have used it, though Cold Steel recently switched to S35VN due to availability concerns. I also have a video that summarizes some of the information below while also showing how some of the experiments work. 14c28n vs. AUS-8 Steel I think this website is aimed at dispelling these kinds of assertions. 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.. But I think it would have much higher toughness than any of the steels on the chart. As wear resistance is increased the differences between conventional and powder metallurgy steels become greater. I also have meat cleaver 1,4116 ,58RC that I order and was looking up if its a good steel or did waist money and need to return it. 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. The chart below has dotted lines which indicate the average effect of hardness for any given steel. Diamond and CBN stones make sharpening those steels easier. Id think that line would be significantly to the left, more in the data swarm. The most balanced is CPM-MagnaCut which is in an area all by itself on the chart. This is the steel used in Swiss Army knives and is excellent for beginner sharpeners. imo o lot depends on how the blade is sharpened. An example of data being processed may be a unique identifier stored in a cookie. 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. The 8Cr13MoV vs D2 debate. Im writing a book about choosing a knife for EDC. What carbon/tool steel would you choose for a survival knife if a PM steel was too expensive? It is most useful for steels with large amounts of carbide but also helps to be able to add certain carbide types. 14c28n steel would be a great pick thanks to its high retention and corrosion, it would be great for a normal EDC knife. Sharpening the knives might be challenging, but the D2 knife is high quality and affordable. 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. 14C28N and D2 steel are not the same. See the chart below showing 52100 steel that was overaustenitized (unintentionally) by a knifemaker that sent me specimens for toughness testing. I am just grasping at straws here, but from the data you shared, it seems like toughness does increase faster than edge retention decreases: it is harder to get a very high edge retention knife that will still be somewhat tough compared to a very tough knife that will still hold an edge ok. The D2 steel compares nicely with 14c28n steel in terms of edge retention, as it's quite hard as well. My name is Jonathan M, and Im a passionate Mechanical Engineer, a knife enthusiast, and the author of this website. Any thoughts how Sleipner might fare in the ratings? VG-1 is a non-powder steel made by Japanese specialty steelmaker Takefu. Some steel companies charge more than others. The Sandvik 14c28n steel is ideal for the manufacturing of steel knife blades. Very obtuse edges resist chipping better but dont hold their edge as long and dont cut as well. Some of these steels also have vanadium (CruForgeV) or tungsten (Blue Super, V-Toku2, 1.2519) for increased wear resistance. 12C27 steel is extremely popular in the US knife market for its high hardness, high wear resistance, and great corrosion resistance. 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. So presumably, wear resistance would be in the 3.5-4 range and toughness in the 5.5-6 range. Let the job at hand be your guide. Poor availability may effectively increase cost of steel. Its called memory metal because heat can get it to revert back to a previous shape. They have many similarities, including their high hardness, strength, and wear resistance. 12C27 1) the cvn number is just that, a number. A mirror finish is the best at resisting corrosion and a rough finish means rust and corrosion is more likely. D2 has been around for more than 20 years, an eternity in. These steels are typically used by forging bladesmiths, traditional folders, and some production fixed blades. However, in our testing there is a reduction in toughness by using the high temperature range rather than the low temperature range, such as was found with CPM-CruWear (Z-Wear) or CPM-10V. XHP is an exceptionally well-balanced steel with excellent all-around attributes. Very much appreciate you. These steels are the good old hard-working steels. And only Vanax and LC200N have been free from corrosion with a 3.5% saltwater solution, though MagnaCut was close. 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. and why would anyone want to use it when 420HC looks so much better for a simple stainless steel option. High Alloy Tool Steel and High Speed Steel Ratings. Without any confusion, you can purchase this set that has a slim, versatile, modified drip-point blade with good slicing capabilities. If youre looking for all all-around best knife steel, youd be hard-pressed to find one better than Bohler Uddeholm M390. I like it. Which one is right for you? D2 steel is high carbon steel with no extra addition of Cr or Mo, that's why it is prone to corrosion. im led to believe tha the melting procedure is more important with these steels than the exact composition. Like 154CM, its a good compromise between all three steel attributes. 2. However, it can be somewhat complicated because an edge can dull from many causes wear, micro-chipping, deformation, or corrosion. 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. MC66 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. 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. Carpenter produces this powder steel. They tend to be relatively expensive and difficult to sharpen, as they have high wear resistance. Lately Ive been edcing one of those instead of a nice folder. 2. It richly deserves its reputation for high-quality gained over the years by Sandvik, a Swedish manufacturer of world-renowned steel. . A2 Knife Steel Air-hardened tool steel. 1095 Hi there, Im looking forward to seeing if it does as well in full production. There one of the best reason that he is highly regarded as a knife designer. I have an article that lists off the major mistakes often made in heat treating. He is the mind and writer behind Knife Steel Nerds, the go-to source for all knowledge about knife steel. Used in knives since at least World War II, 1095 performance varies considerably with an abundance of tweaks in the recipe and heat treat. Another is that 8Cr13MoV is a generic name for a specific composition while AUS-8 is a name of a product by a specific company. There are significant differences between them because 14C28N is stainless steel, while D2 steel is a semi-stainless tool steel. Spyderco announced Native 5 Salt with magnacut, but I saw test of magnacut with salt water and it grows corrosionso Salt with magnacut could be a flop. 14C28N VS D2 The two sheets of steel are comparable in terms of toughness and corrosion resistance. It shows 3 stainless steels from 750-800tcc but the edge retention graph only has 1 SS in that range, S90v. Although it should be noted that there doesnt seem to be a need for the stainlessness on a wood working tool. Opinel Number 9 in carbon steel, and a Cold Steel Tanto Lite in their stainless steel. The majority of knives target 63 Rc or below so this limitation of stainless steels does not always come into play but can be an important factor for certain knives targeting high performance and thin edges. BD1 isnt terribly hard but sharpens easily. We did the research to help you find the best hunting knife for your needs and budget. The vivid patterns visible in Damascus steel come from the acid etching process in a ferric chloride solution. 420HC, 420, and 5160 all offer off-the-charts toughness. Divers, sailors, and anglers need knives that will resist corrosion above all else. HA! Furthermore, because of its ultrahigh hardness, Maxamet is very prone to corrosion, probably worse than 1095. 1095 stains easily and thus is often coated, especially in fixed blades. Its actually quite good, low-cost steel that performs like midprice steel.
