A high-carbon martensitic stainless steel strengthened by cobalt and tungsten additions, designed to achieve extreme hardness and wear resistance while retaining corrosion resistance in the 13–14% chromium range. This variant is tailored for demanding applications requiring both edge retention and environmental durability, sitting at the intersection of tool steel and stainless steel performance. Engineers select this alloy when conventional tool steels lack sufficient corrosion resistance or when martensitic stainless grades need enhanced hardness and thermal fatigue resistance for high-stress cutting, forming, and molding operations.
