16Cr Martensitic Stainless (var. 15)

16Cr Martensitic Stainless (var. 15) is a high-carbon, precipitation-hardened martensitic stainless steel alloyed with cobalt, molybdenum, and vanadium for exceptional hardness and wear resistance. This material is engineered for demanding applications requiring both corrosion resistance and extreme strength, typically found in aerospace turbine components, high-performance cutting tools, and precision bearing races where conventional martensitic stainless steels cannot meet performance thresholds. The cobalt addition and elevated carbon content distinguish this variant as a premium choice when superior edge retention, fatigue resistance, and oxidation resistance must be balanced—though it sacrifices some toughness and machinability compared to lower-carbon martensitic grades.
