S30V VS 20CV. Strength and toughness are comparable to that found on VG-10 or 154CM. Don't confuse BD1 with its bigger, badder brother BD1N. What is its hardness? How is the corrosion resistance on 20cv? CPM 20CV is a martensitic steel, which refers to its hard crystalline structure with lens-shaped or lenticular grains. This is why 3% vanadium 3V has much better toughness and grindability than the 10% vanadium 10V, though at the cost of wear resistance. 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. You must log in or register to reply here. Crucible started with 154CM as their basis, replacing 2% Mo with 2% vanadium. My understanding is the sheepsfoot has a hollow grind and the drop point has a sabre grind. JavaScript is disabled. According to the chemical composition and the HRC of the steel, the CPM S30V Steel has the following features: Edge Retention: With a maximum of 61HRC due to the mixture of Tungsten, Vanadium, Manganese, and Carbon, the CPM S30V offers a great hardness followed up by an excellent Edge Retention. N690 is an extremely ubiquitous and popular steel among knifemakers in Europe. Are you in a humid, wet, and salty environment? CPM-M4 is a bit of a different animal though, it's harder and tougher than m390, CPM-20CV or CTS-204P, but it's a lot less corrosion resistant than any of those three. Does Bohler-Uddeholm sound like a stinky cheese to you? LC200N is an amazing steel! 4 inch 20CV blade. So what about all the other steels that didn't make it on the list? Performance of all the 400 Series steels is quite similar, but you will see slight variations among the different compositions. Get a free guide on Knife Sharpening to find out how you can achieve more. Do you frequently use your knife to meal prep acidic ingredients like citrus or tomatoes? [4] Chilton’s iron age 226, no. The edge retention of S30V is still pretty good relative to other knife steels, better than steels like XHP, Elmax, 154CM, 440C, etc. S30V was designed to offer a “balanced” stainless steel which could offer good grindability, toughness, corrosion resistance, and edge retention. All stainless steels are exposed to rust if you neglect to take care of them for a long period. As the others have mentioned, its only downfall is that it can be a bear to sharpen. The ZT 0350 is a certified beast. S90V offers high edge retention with low toughness and the same corrosion resistance compared to S30V. It is a bit below steels like ZDP-189, S90V, and 20CV/M390. Worth $200 bucks for a custom knife in 20CV then? Being able to field sharpen your knife can be the difference between life and death in the wilderness. High hardness (60 HRC+) increases the edge retention of the steel at the cost of brittleness. Knife steels that exhibit extreme hardness and edge retention are amazing at cutting through warehouses full of cardboard but hit a staple and your knife may suffer a chip. Powdered steels are more consistent, have better edge retention, and improve toughness due to a lack of inclusions. This is one of those most ubiquitous steels in knives. And thanks to Dick Barber for talking to me about the development of S30V. Tough steels excel at camp chores and batoning wood but are unable to be used at very thin edge profiles while maintaining edge stability. 21 (1983): 53. As such, the performance of the steel is entirely dependent upon the steels being utilized. “Powder-metallurgy steel article with high vanadium-carbide content.” U.S. Patent 4,249,945, issued February 10, 1981. 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. “Corrosion resistant, high vanadium, powder metallurgy tool steel articles with improved metal to metal wear resistance and a method for producing the same.” U.S. Patent 5,679,908, issued October 21, 1997. and other questions) in this blog post, so let us dive in! Carbon steels will pit and rust aggressively in wet environments if not properly cared for. Personally, excitement over the release of S30V in 2001 was part of what led me to become a metallurgist and to eventually research and write for this website. If you’re using it as a knife, once you finish using it A simple wipe will keep your knife rust-free. The resulting edge retention is better than steels like Elmax, S35VN, CPM-154, and BG42, though a bit worse than S90V and M390. Abuse it. The difference with H1 is that you can literally leave it in salt water forever and it won’t rust. The early versions of the steel were first tested by Chris Reeve Knives making that company very significant to what the final product became. A 30 degree inclusive edge means that each side of the blade is sharpened to 15 degrees. CPM-20CV can be found on my knives today and is made by the USA-based Crucible Industries. Therefore, having only vanadium carbides means a better wear resistance-toughness balance. 20cv vs s30v. When it comes to getting the job done there are four main factors that determine steel quality. See this article to learn about corrosion resistance. With the improved balance and the improved steel, it should be a real winner. With my own CATRA experiments the relative position of S30V is approximately the same, but I will be talking about those experiments in a future article. Ive only ever had 154cm and S30V from benchmade, and many other steels from different manufacturers, but I"ve never heard of M4 or 20CV. Cutting and slicing performance improves as the thickness behind the edge decreases. A2 has long been known as the classic standby for a fixed blade steel. Get Up To 95% Off Today! Don’t worry—we’re going to break down and compare all the best knife steels you can expect to find at Blade HQ so that you can determine the supreme steel for your needs. 420HC has close corrosion resistance, toughness, and low edge retention compared to the S30V.
