A highly wear resistant, powder metallurgy stainless tool steel with a unique combination of high wear resistance, high corrosion resistance, good impact toughness, and excellent polish ability. 20CV contains 20% chromium and 4% vanadium, which is the highest level of chromium in any high vanadium stainless tool steel available today. These qualities make 20CV well suited for a wide variety of industrial and custom knife applications. Carbon-1.90%, Manganese-0.30%, Chromium-20.00%, Vanadium-4.00%, Molybdenum-0.60%. Zero Tolerance has decided to switch almost exclusively to 20CV, and Benchmade has been experimenting with it as well.
