The various cutlery steels may be filtered by type: Stainless; Non-Stainless; Alternate Alloy (generally, alternatives to steel) Temper for 2 hours. ... As noted previously – hardness does not imply toughness. CTS™ 204P is a powder metallurgy, chromium/vanadium stainless steel. Help & support for the Knife Steel Chart for Android. Information Pages: PM2 in M390, CTS-204P and CV20 same manufacturer, same model. With significant amounts of Chromium, Molybdenum, Vanadium, and Tungsten, these steels are 100% ready for action. Not really. And if we take into account all the cutting tests we carried out we can also say that, in terms of performance, they are also similar. 20CV and M390 are shown in the table above for comparison purposes. We have several pages of information about materials and other subjects. CTS-204P is indistinguishable from it in use and 20CV in my use pulls ahead of both. Austenitize: Heat rapidly to 2050°-2150°F. Higher austenitizing temperatures maximize edge holding. Select steels from the Interactive Knife Steel Composition Chart. I am always glad when people are on the same page as me when it comes to edge geometry over steel composition! Steel Composition Chart. What Makes a Steel? Temper: Temper immediately after cryo or quench if cryo is not performed. Pretty cool stuff really.
