15Cr martensitic stainless steel (variant 10) is a high-carbon, cobalt-strengthened martensitic stainless alloy designed for applications requiring exceptional hardness and wear resistance. The elevated carbon and cobalt content, combined with molybdenum and chromium additions, enable this steel to achieve high strength through martensitic hardening while maintaining corrosion resistance in moderately aggressive environments. This material bridges the gap between tool steels and corrosion-resistant alloys, making it suitable for demanding applications where both wear performance and some corrosion tolerance are required.
