13Cr Martensitic Stainless Steel (var. 22) is a high-strength, cobalt-reinforced martensitic stainless steel designed for extreme-hardness applications requiring corrosion resistance and wear resistance in a single material. The elevated cobalt content (~9.6%) and molybdenum addition distinguish this variant, making it suitable for demanding aerospace, tooling, and high-performance industrial applications where both hardness and corrosion resistance are critical. This material offers a balance between the brittleness concerns typical of very-high-carbon martensitic stainless steels and the toughness requirements of service environments.
