I use an Edge Pro system and don't have much of an issue with it, just takes time and patience. The molybdenum was added so that the bearings could be operated at high temperature, but it was discovered that partially replacing Cr with Mo led to similar corrosion resistance to 440C. 20CV better in about every single way except ease of sharpening. There’s no doubt—H1 is a specialty steel. Both of these steels are a real bear to sharpen up! Elmax can be found in many Microtech knives. S30V and S35VN are very similar for corrosion resistance. Maybe one of the most frequently overlooked aspects of blade steel is sharpenability. Abuse it. Tough steels excel at camp chores and batoning wood but are unable to be used at very thin edge profiles while maintaining edge stability. Become a patron and gain access to awesome rewards including early access to articles or a Knife Steel Nerds mug! The edge retention of S30V is still pretty good relative to other knife steels, better than steels like XHP, Elmax, 154CM, 440C, etc. In contrast, a more obtuse angle will be more stable and durable. This is a small list of steels that aren't necessarily in high production anymore, but still offer high-end or mid-range performance. All you have to do is click to be taken to What is its chemical composition? The edge retention of S30V is still pretty good relative to other knife steels, better than steels like XHP, Elmax, 154CM, 440C, etc. Crucible Industry's CPM stands for Crucible Particle Metallurgy. 154CM was designed for bearings, and was essentially a modification of 440C by reducing the chromium (Cr) by ~3% and adding 4% molybdenum (Mo). The goal of many knife users is to find the best steel to fits their needs. S60V is not a bad steel and has relatively high edge retention, but its grindability and toughness are also relatively poor and its corrosion resistance is only mediocre. Good edge retention, toughness, and sharpenability, D2 has been a popular knife tool steel dating back to WWII, and for good reason. [3] “Powder metallurgy tool steel article.” British patent 1443900, issued July 28, 1976. S30V also needed to be easily heat treated with common knife heat treating equipment which was why Paul Bos was consulted. S30V is tougher... tough to sharpen and once sharpened, tough to lose the edge. Or will the difference between them not be very big? Bohler-Uddeholm produces more than just the famous M390 steel. Heat Treatment: Austenitize 1950°F (1065°C). It may seem like there’s a big step down between a steel like S110V and CPM 154. https://knifesteelnerds.com/2018/11/19/steel-edge-retention/, But read a few of the edge retention articles… there is a huge context. 20cv will hold an edge the longest, so if you don’t plan on beating on the thing I would go with that. And less chromium carbide means that even though S90V has less chromium, less is tied up in carbides so that the chromium is free in the steel to improve corrosion resistance. CPM-3V is, in many ways, the perfect blade steel for a fixed blade knife. Generally speaking, the higher the number at the front, the better the steel. S35VN offers slightly better performance compared to the S30V. Often overlooked is the job at hand. It is a bit below steels like ZDP-189, S90V, and 20CV/M390. Finer grained powder steels can take a sharper edge. All steels can get equally sharp! Which is bull, anybody who knows anything about knives will tell you a quality fixed blade is inherently sturdier than a folder, since there's no lock to fail on you. Touching up certain steels with your sharpening stone is an easy, pain-free process whereas harder steels can make for an all-day affair to bring them back to sharp. Damascus or ‘pattern welded’ steel is a result of combining two steels together. Crucible developed several powder metallurgy steels including 10V, S60V (formerly 440V) and S90V (formerly 420V), but none of them really gained wide use in knives. The difference with H1 is that you can literally leave it in salt water forever and it won’t rust. Some people are uncomfortable carrying a knife that is susceptible to rust and corrosion, but keep your blade oiled and there won't be any problems. Heat treat, blade geometry, the job at hand, and the sharpening of the blade all play a massive role in the performance of the steel. It was also somewhat finer than the previously available S60V and S90V. Another fact known is that a reduced carbon and vanadium content would lead to a steel that was tougher and easier to grind because of a reduction in overall carbide content. Thanks in advance. And yesterday I went into my local outdoors/hunting shop and guess what's staring at me when I walked in? VG-10 exhibits many of the same qualities of 154CM with the largest difference being an increase in corrosion resistance. Performance of all the 400 Series steels is quite similar, but you will see slight variations among the different compositions. [6] https://www.bladeforums.com/threads/the-true-history-of-s30v-development.1015831/, [7] https://www.bladeforums.com/threads/chris-reeve-green-beret.384825/page-5#post-3538203. However, in testing of that steel Chris Reeve Knives wanted more wear resistance to better differentiate from BG42, leading to an increase in vanadium up to the final 4%. Based on experience and testing, M4 steel may outperform blade steels such as M390 and S90V in terms of edge retention and M4 is in a completely different league in terms of toughness. Get a free guide on Knife Sharpening to find out how you can achieve more. Subscribe to our newsletter to get a free guide on ”your subject”. Compared to forged steels, powdered metallurgy based CPM steels have a very fine grain structure and far fewer inclusions. See this article to learn about corrosion resistance. As you can see, the CPM S30V is stainless steel with 14% of Chromium, high in Carbon (more than 1% of carbon), high in Molybdenum and Vanadium which makes high-end stainless steel. If you’re using it as a knife, once you finish using it A simple wipe will keep your knife rust-free. Compared to CPM-3V, A2 is available more much affordable and is much more easily sharpened. In head-to-head testing, you would struggle to discern a significant difference between the two knife steels, but under a microscope you will see improved toughness and sharpenability (S35VN is a dream to sharpen when compared to S110V). This is one of those most ubiquitous steels in knives. I say go for it. As a Powder Metallurgy (PM) tool steel, you get a combination of impressive wear resistance and edge retention plus the added benefit of being highly corrosion resistant due to high levels of chromium. Carpenter-produced CTS-XHP is one of the most well-rounded and versatile steels. CTS-204P is made by the USA-based Carpenter Technology Corporation and CPM-20CV is manufactured by Crucible Industries. With poor grindability and little stain resistance it has never been used much outside of individual custom knives. Whether it’s dicing up cardboard boxes, feather sticking some firewood, or hacking up sisal rope, no one likes a dull knife. Advantages: Wear resistance, corrosion resistance. CPM-20CV is Crucible’s version of Bohler’s popular M390 steel which also influenced Carpenter to copycat with CTS-204P. Chromium and vanadium both compete to form carbides. A knife with great edge retention will vaporize cardboard even after months of carry. The primary difference is out-of-this-world edge retention at the cost of a minimal reduction in toughness. Hey guys.. do you have a list of blade steels in order of edge retainability.. S90V offers high edge retention with low toughness and the same corrosion resistance compared to S30V. Below shows the results of CATRA experiments reported by others that I have shown in other articles. CPM-S110V exhibits many of the same qualities as S90V. Additional considerations include the thickness of the blade stock and the primary grind. And thanks for the info. The toughness measured was good, though could possibly be improved through more optimized heat treatments than what I used. In this section, we’re going to compare our steel with other steels, and for this, I use four criteria; Edge Retention, Corrosion resistance, Ease of Sharpness, and Toughness, and I use a scale or note from 1 to 10. The great thing about cutlery, is that any knife can get equally sharp regardless of steel. As always if you have another opinion about the CPM S30V, please share it on the comments below, I ‘ll gladly discuss knives. Cool to hand warmly between tempers. Chris said that if Crucible made something better they would buy it. S30V is a knife steel produced by Crucible, released at the end of 2001 [1]. As the others have mentioned, its only downfall is that it can be a bear to sharpen. Carbides are hard particles in steel that add to wear resistance but detract from toughness. So even as S30V is replaced to some extent, it is often by steels that owe some of their design to the older S30V.
