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 1.4116 I tested has large carbides in it which is presumably the reason for low measured toughness: https://knifesteelnerds.com/2019/05/26/new-micrographs-of-42-knife-steels/. Instead, Vargo titanium uses a unique material called sintered titanium-ceramic alloy. My other knives are a Real Steel E77 8cr14mov. 1. LC 200N is an elite performer, with high hardness, high toughness, and off-the-charts corrosion resistance. If you purchase this types of knife, without any hassle you can easily re-sharpening. Knives are one of our oldest tools, so it makes sense that they have evolved into thousands of styles since the first person chipped one out of stone. Is 14C28N Steel Good Steel? - Knifebasics There are significant differences between them because 14C28N is stainless steel, while D2 steel is a semi-stainless tool steel. M390 Have you tested K390 sufficiently to be able to rate it? Not every element is shown in the charts. Ive found S35VN less chippy even at the same hardness. The hardenable grade of titanium (Beta C Titanium) reaches up to 45 or so rc. AR-RPM9 For these reasons D2 steel is a good for smaller folding knives, but is not ideal for large fixed blades such as dedicated choppers and large survival knives. 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. The studies confirmed that the primary controlling factors are hardness of the steel, volume of carbides, and hardness of the carbides. Because of its abrasion-eating hardness, knives with REX 121 come at an exceptionally high price. Heat treatment refers to the heating and cooling steps employed to achieve your knifes proper balance of attributes. One of the more common stainless steels, and one readily available in lots of different places worldwide, AUS-8 is a decent all-around steel. CPM 4V I havent tested Sleipner yet. You can see micrographs of different knife steels to compare their carbides in this article. It confirms what I always suspected and what anyone could have figured out by reading the technical data. 14C28N is a stainless steel that was developed specifically for use in knives. A hunting knife has a singlepurpose: processing meat after akill. On the other hand, 9cr18mov has a slightly higher molybdenum content which gives it higher hardness from quenching and helps drive carbide formation. One important concept I want to hammer home is that there isnt one property that is most important. document.getElementById( "ak_js" ).setAttribute( "value", ( new Date() ).getTime() ); Enter your email address to subscribe to this blog and receive notifications of new posts by email. There is no such thing as a steel that is a 10 in both toughness and edge retention. Great for tensile strength and Edge retention. Metallurgy and Testing of Knives and Steel. This is a non-powder Japanese steel used primarily in Spyderco knives. Around 61 Rc usually. The line is only in the neighborhood of 5 of the datapoints. 14C28N vs D2 - knifebasics.com D2 steel does not contain enough chromium to make it stainless steel. 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. Thanks in advance, Simon, For hard use everyday cutting in a packing company, Everything from fome, cardboard, tape, thick plastics, And plastic wrap that is against metal. Here, we will discuss edge retention, toughness, ease of sharpening, and corrosion resistance. For this perfect size that for most tasks and the slim tip allows the knife to excel at piercing and detail work. 14C28N is a type of high-performance stainless steel used in knife-making. But unlike most high-end steels, SPY27 is an easily user-serviceable powder steel. 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. I was struggling to simplify all the Rockwell/Youngs Modulus stuff for readers when I came across your site. For example, Bohler M390, CTS-204P, and CPM-20CV are all nearly identical and indistinguishable in practice. It improves wear resistance and hardenability. It has an HRc over 70, usually even harder than Maxamet. How long sharpen? There are so many interactions between them that predictions are difficult without modeling software. I wont go into detail about those here. Monday-Friday Therefore, ensure to wash and dry your knives after use to keep the rust away. Its a good balance between all three attributes, being relatively hard, tough, and corrosion-resistant. Austenitizing is the process where the steel is heated to high temperature prior to quenching (rapid cooling) to harden the steel. We looked at common steels used by popular knife brands to help you select the right material for your blade. If youre having trouble finding the steel you want, see if another manufacturer makes something much like it. FRN With a high level ofedge retention, corrosion resistance, and toughness, it does most everything quite well. It rusts like nothing Ive seen before and it dull just by looking at it. A2 is a tool steel renowned for toughness. 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.. 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. While 9Cr18MoV steel is highly corrosion resistant due to the addition of Cr, and Mo. CRKT and Spyderco use BD1. Properties: 14C28N: D2: Edge retention: 4/10: 7/10: Ease of sharpening: 6/10: 3/10: Corrosion resistance: 4/10: 4/10: Toughness: 6/10: 6/10: CIVIVI Knives Elementum Folding Pocket Knife 2.96" D2 Satin Blade . 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. Vanadium carbides are very large with conventional production of steels but are very small with powder metallurgy. There you said 7.6 for 420HC. Jeff I worked at a company that heat treated D2 (1.55% C) planer blades for a company that built wood working equipment for commercial shops. : at a given toughness, magncut will have better edge retention in real life applications than s90v if it has optimal geometry (or maybe it wouldnt, just an example). They are usually chosen for their looks rather than performance. 14c28n Steel - Is it Good for the knife?

And steels with at least 10% chromium are probably stainless, except for several important exceptions like D2 and ZDP-189. I have a Winkler Knives Recon model in 5160 steel and even though the knife model is ok, the steel is shit. Combination of knife steel properties. INFI is also quite hard and sharpens easily. Unfortunately a high amount of it decreases strength. 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. There are significant differences between them because 14C28N is stainless steel, while D2 steel is a semi-stainless tool steel. The Sandvik 14C28N has a very thin and sharp blade that is perfect for slicing through things. Thanks. This particular steel grade allows for the highest attainable hardness without. The critical difference between these two sheets of steel is their corrosion resistance. Hello LARRIN, do you have a Rough estimate on when ApexUltra (as well as more Magnacut) will become available? Rowens heat treat on ESEE knives that use 1095 is exceptional; KA-BARs is less so. At the end of the article I gave a list of reasons why I hadnt made my own ratings chart, two big reasons were: 1) I didnt yet have articles explaining what edge retention and toughness even is (this was early on in Knife Steel Nerds), 2) I didnt have good experimental numbers on many steels. its like with cars, most of them are not a corvette or a porsche. 14C28N and D2 steel are not the same. But it doesnt have great wear resistance and thus doesnt hold an edge particularly well. Different companies can vary some between each other making the same product, while a single company is going to be more consistent. It also improves edge retention and strength. Aluminum oxide is used in most common sharpening stones and it is softer than vanadium carbide, which makes sharpening high vanadium steels more difficult. A lot of custom makers also like S110V, including the great RJ Martin. Im a woodworker and Im interested in making better performing plane irons and chisels. In other words, heat treating a steel to its maximum hardness does not necessarily mean reduced corrosion resistance. n690 Steels that can be high in edge retention and toughness are desirable for general use knives. 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. i understand the samples were treated in the same way. 14C28N, designed by Sandvik at Kershaw's behest to have the edge properties of 13C26 but with increased corrosion resistance by adding nitrogen and chromium. And a label: AEB-L. What is the Best Budget Knife Steel? - Knife Steel Nerds The bump in hardness comes from precipitation of fine carbides in the steel, read an article I wrote on budget steels here, https://knifesteelnerds.com/2019/05/26/new-micrographs-of-42-knife-steels/, https://i0.wp.com/knifesteelnerds.com/wp-content/uploads/2021/10/stainless-toughness-10-19-21.jpg?w=757&ssl=1, https://knifesteelnerds.com/2019/10/14/corrosion-resistance-testing/, https://knifesteelnerds.com/2020/03/02/cpm-spy27-experiments-toughness-corrosion-resistance-and-more/, https://knifesteelnerds.com/2018/12/03/cryogenic-part1/, https://knifesteelnerds.com/2018/12/10/cryogenic-processing-of-steel-part-2/, https://knifesteelnerds.com/2018/12/17/cryogenic-processing-of-steel-part-3/, The Pros And Cons Of Stainless Steel Copper And Aluminum Brewing Equipment SanctuaryBrewCo, https://knifesteelnerds.com/2020/05/01/testing-the-edge-retention-of-48-knife-steels/. The Vargo Sobata 398 is unlike any other knife on this list. The biggest change that is seen with powder metallurgy in measured properties is in regards to toughness. 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. 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. 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.
