16Cr Martensitic Stainless (var. 4)
metal16Cr Martensitic Stainless Steel (variant 4) is a high-carbon, cobalt-reinforced martensitic stainless steel engineered for extreme hardness and wear resistance through precipitation hardening. The elevated carbon content (0.8%), vanadium, molybdenum, and significant cobalt addition (13.1%) create a material optimized for applications demanding superior strength and edge retention, positioning it between conventional tool steels and premium stainless grades. This composition suggests a specialized tool or wear-resistant application steel, chosen where corrosion resistance must coexist with the hardness and toughness typically reserved for non-stainless martensitic alloys.
