13Cr Martensitic Stainless (var. 24)

13Cr martensitic stainless steel (variant 24) is a high-carbon, cobalt-strengthened stainless alloy designed for demanding applications requiring excellent hardness and wear resistance. The elevated carbon content (~0.5%), combined with cobalt and molybdenum additions, enables this material to achieve superior strength through martensitic hardening while maintaining corrosion resistance typical of 13% chromium grades. This variant represents a specialized composition optimized for applications where conventional martensitic stainless steels require enhanced performance—often seen in tool steels, precision components, and corrosion-resistant wear-critical parts that balance toughness with resistance to abrasion and chemical attack.
