Not so sure of that anymore. Whilst both steels will do a good job for most of your day-to-day tasks, there's a noticeable difference in quality between the S30v and 420HC steels when it comes to performance and price. When heat treated to HRC62 or higher M390/20CV also provides a considerable and noticeable increase in wear resistance over S30V. The PM process combined with the high chromium content imparts M390 / CPM 20CV with good grindability and excellent polishability. I selected the following . Both CPM steel types offer excellent edge . The exceptional hardness, edge retention, and wear/corrosion resistance make the M390 the best steel to make knives. Chemical . CPM-M4 vs CTS-20CP/CPM-S90V. Both are very high on edge retention, but M4 can take more abuse (cutting more abrasive media) and still slice cleanly. It is not as tough as a steel like AEB-L at 61 Rc because AEB-L has less carbide and . 440C is a martensitic stainless steel with excellent corrosion resistance and a high degree of hardness at HRC 58 to 60. Author : Skibitski, Robert Created Date: 5/10/2013 8:09:55 AM . BMW M8 9/10. Feel: I found the M3/M4 both felt nicer over all vs. 2017 M2. It can be hardened to around 62-64 HRC but note M4 is a carbon steel is not considered stainless with relatively low levels of chromium . As a result, it comes down to your personal preference. CPM M4 provides superbly balances levels of abrasion resistance and toughness through high doses of molybdenum (hence the "M"), vanadium and tungsten together with reasonably high levels of carbon. M4 blows S30V out of the water with far superior edge retention, easier sharpening, and higher toughness. If you were comparing CPM-M4 to CPM-3V for such a tool the decision would be far more difficult. You'll find S30v steel in many high-end . (1 is poor performance, 10 is exceptional . 20CV's edge retention is noticeably better than S30V, meaning that a blade crafted from this material will hold its edge for longer, meaning less sharpening and more cutting power.

M390 /20Cv provides considerably better corrosion resistance than S30V. I will say that my dispersion on off-centre hits carried farther and stayed straighter with the m3/m4 vs. the 2017 m2. 20CV is way more corrosion resistant M4 has much higher toughness Edge rentention is a different discussion alltogether. In other words, the steel composition is more important for carbide size than the production process. You can get your hand on a decent quality M390 knife for around $300-500. M390 / CPM 20CV is a PM stainless steel that offers good wear resistance with excellent corrosion resistance through the use of high chromium and vanadium content. At one point m390/20cv/204p was seen as a stainless M4. CPM 20cv Corrosion Resistance: with 20% of chromium in the CPM 20CV steel, CPM 20CV has excellent corrosion resistance, might be the best in the knife steels. The . M4 is one, and M390 (aka CPM-20CV aka CTS-204P) is the other. Vanadium is a very difficult and expensive material to work with and as such, S90V blades are insanely expensive . As it turns out, 20CV's corrosion resistance is, in fact, a little better than S30V, but where the real difference comes in is edge retention. 575 State Fair Blvd., Solvay, NY 13209. www.crucible.com. M4 steel vs S90V. The steel is primarily used to make high-end custom knives. CPM M4. But they performed pretty similar in this test. CPM M4 steel vs S30V. Next Last. CPM M4 is at least a third tougher than CPM 20CV, with equal wear resistance and perhaps one-seventh the corrosion resistance. Durability. S30v vs 420HC - Usability. 800-365-1180 315-487-4111. CPM 20CV is the more corrosion resistant version of the high tier CPM family. Properties for the M4 are among the most-balanced around, faring very well for its toughness according to some user observations. Comparisons must consider whether a user places high priority on edge retention or not; as well as on corrosion resistance since Maxamet is vulnerable to rust if not cared for properly. motorola g82 vs iqoo neo 6|| Full Comparison Of motorola g82 vs iqoo neo 6 || Poco M3 Vs Poco M4 reviewHello friends welcome to comparison. Sharpening s30v is easier compared to cpm 20cv. What it is: CPM M4 is a "Crucible Particle Metallurgy" carbon tool steel, widely regarded as a "super steel" for its properties and performance. All-Around: M390, CTS-204P, and CPM-20CV If you're looking for all all-around best knife steel, you'd be hard-pressed to find one better than Bohler Uddeholm M390. Each steel is evaluated in terms of four performance characteristics: edge retention, toughness, corrosion resistance, and ease of sharpening. Some observations: S30V is a pretty darn good steel.

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. CPM S90V sacrifices a little of the 20CV corrosion resistance for an even harder blade consisting of much less chromium and a whole lot more vanadium. When it comes to all around functionality, you can't beat the Griptilian. We may see a slightly different result when using the exact same edge geometries, and polished edges, and while cutting some other media. The M4 has a slight edge over the hardness and the grindability whereas the S90V stands out in toughness and anti-corrosion properties. These numbers would show that my current 2017 m2 gamer might be the way to go.
