13Cr Martensitic Stainless (var. 22)

metal

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.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
