a burr might have developped on some of the steels and not on others, it might have ben reduced or even removed by the process. 14C28N steel holds good hardness. . Actually, Id be thinking 14C28N, but I want to leave stainless out. Steel with high wear resistance is more costly to manufacture, as the knife company goes through more abrasives to grind the knives. But it would be my recommendation for applications requiring extreme corrosion resistance. Interesting. On the other hand, Speed safe assisted opening allows for easy blade deployment with the use of a simple pull back on the ambidextrous flipper. It mainly made for knife and it high in Chromium for excellent corrosion resistance. This is a non-powder Japanese steel used primarily in Spyderco knives. I do not have rust issues with it (as long as I have a good finish) some heavy stonewashed finishes rust easier. Vanax gives up some toughness and hardness vs MagnaCut for saltwater levels of corrosion resistance. H1 Ive found that most makers harden S30V too much, making it prone to chipping at the edge. The edge retention and ease of sharpening have been what we expect with D2. D2 is not a bad steel, but it has been around a long time and is somewhat mundane by current standards. The best steels with balanced properties include 4V/Vanadis4E, CPM-CruWear, and CPM-M4. CPM-REX 121 and Maxamet are both in this category. 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. It will take you more time and energy to get a sharp edge, but your efforts will pay off because the blades hold the edge longer.

If you want to learn more about a specific steel, you can click it in the sorted listings below. Another common heat treating choice that is not even categorized as a mistake is tempering in the high temperature regime (~1000F) rather than the low temperature regime (~400F). REX 121 is a powder steel produced by Crucible. A2 knives need care taken to avoid rust and are often coated to inhibit corrosion. The definition of a quality knife differs among users because of varied needs, but there are basic properties that every quality knife must have. Would be great if some manufactures changed their steels based on this information. It rusts like nothing Ive seen before and it dull just by looking at it. Is Vancron SuperClean a good choice for a chef knife? List of blade materials - Wikipedia 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. Using 10 dps sharpening (20 degrees inclusive on the chart) leads to about 5x the edge retention of 25 dps. 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. Poor heat treatment can make a knife too hard, too soft, hard to sharpen, easy to deform, or cause other issues. But then if you look at an increase of 100 mm in the CATRA test from Maxamet to Rex 121 the toughness only drops 1-2 ft-lbs.

In this article, we will discuss the characteristics, pros, cons, and differences between 14C28N and D2 knives to help to make the right choice. XHP is an exceptionally well-balanced steel with excellent all-around attributes. Distilled water can separate steels that are stainless vs those that are not. 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. AEB-L and 14C28N are the best in the high toughness group. Theyre excellent for choppers, hard-use folders, and outdoor knives that see impacts and heavy use when used at medium hardness. It mainly made for knife and it high in Chromium for excellent corrosion resistance. Required fields are marked *. Note:Dont bother with anything less than 8Cr in this series. . For the steels that I rated I give them a single rating rather than a range based on different heat treatments that can be performed. Like 154CM, its a good compromise between all three steel attributes. In general, higher carbon and higher vanadium steels have higher wear resistance and edge retention but lower toughness. But in use, Ive found nothing that withstands the abuse that 3V can take. The material increase machinability and strength. I have a bachelor's degree in Mechanical engineering with a specialization in material science. Most low alloy tool steels and carbon steels also have fine carbide structures without powder metallurgy processing. 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. 14C28N steel is known to offer among the best if not the best toughness in knife steels out there.

These properties make steel a good choice for making kitchen, fishing, and everyday knives. The D2 knife blade offers high edge retention and wear resistance. Therefore, you cannot purchase the knife for use in corrosive environments. In many cases the cost of working with the steel for the knife companies is more significant than the cost of the steel itself. 440C steel With steels that have a small amount of carbide the size of the carbides can be kept small through processing (see the AEB-L micrograph earlier in the article). Great for tensile strength and Edge retention. 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. Hi Larrin Your estimate of 420HCs corrosion resistance is different here than in your October, 2019 post on corrosion resistance testing: https://knifesteelnerds.com/2019/10/14/corrosion-resistance-testing/ 14C28N knives offer better toughness than D2 knives. Lots of information is still specific to this article, however. Even though it has very high hardness, its also still decently resistant to corrosion and quite tough.

Im not hating on 80crv2 , Ive used it. Its possible that there are steel manufacturers with better processing which would lead to an even carbide distribution but I cant say that without seeing it for myself. 14c28n vs. AUS-8 Steel Obviously Ill let you check the manuscript prior to publication. While higher hardness does lead to improved edge retention the bigger reason to have higher hardness is for resisting edge deformation. Sorry, most of my previous comment was borderline word salad. Advantages: Toughness, edge retention. They tend to be relatively expensive and difficult to sharpen, as they have high wear resistance. : 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). I have a few examples below for steels that I have ranges of hardness tested for both toughness and edge retention. Why does Maxamet and Rex 121 stay the same tcc but Zmax drops and 15v goes from below 900 to over?

ZDP-189 can tarnish, though not as easily as 3V. 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. The ratings in this article rate ease of sharpening primarily based on wear resistance, but if a knife is difficult to sharpen, there may be other factors in play. That provides 14% Chromium and offers excellent corrosion resistance. Id like to quote some of your toughness, edge retention and corrosion resistance for balanced midfield steels, including yours, in some data tables. How Is 14C28N Steel for Knives? Can you contact me via my email address so I can send you a copy in PDF and epub. While quite soft, the metal cuts even when it seems dull because, at the microscopic level, it has a roughness that performs much like a serration. Thanks to powder metallurgy, youll find even better edge retention on the high end. So you can estimate how much a change in hardness would affect edge retention by following the slope of those lines. In general, the more carbide the steel has and the larger the carbides the lower is the toughness. 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. 14c28n is the most popular material for the knife: stainless steel and made by the Swedish company.

The ratings I have are for an optimal heat treatment. 1% saltwater will separate between other stainless steels. Steels that are improperly heat treated have excess retained austenite which makes them extremely difficult to deburr. Stainless steels are more resistant to corrosion but remember that stainless steels stain less, and most of them will still rust in the right conditions. the more complex fracture toughness at least lets you make some estimates in this sence. But the true calling card of INFI is its insane toughness. Is 440A really that much better than 420HC, or have you found a narrower gap? Diamond and CBN stones make sharpening those steels easier. Rex 45 I like it in the Seki City Spydercos, but I would like to know what ratings you would give it. A few steels have been added since such as MagnaCut and M398. Therefore you will use it for a long time without requiring frequent sharpening. How would n680 compare to m690? For example, increasing edge retention from Z-Tuff to 3V (100 mm in the CATRA test) led to a drop in over 10 ft-lbs, a similar drop is seen by going from 3V to CPM-CruWear. Three main characteristics differentiate steels from one another: corrosion resistance, hardness, and toughness. While 9Cr18MoV steel is highly corrosion resistant due to the addition of Cr, and Mo. 14% of Chromium: Increases corrosion resistance and wear resistance. https://www.patreon.com/Knifesteelnerds, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window). Below shows the results of MagnaCut testing vs other steels where it is labeled as New Steel.. Stainless steels are another subset of high alloy tool steels that have enough chromium in them to have stainless levels of corrosion resistance. They are usually chosen for their looks rather than performance. Toughness is a measure of how much resistance a steel has to fracturing. D2 steel, on the other hand, is tool steel, and its knives shine on edge retention and wear resistance.
