14Cr Martensitic Stainless (var. 8)
metal14Cr Martensitic Stainless Steel (variant 8) is a high-carbon, cobalt-strengthened martensitic stainless steel engineered for maximum hardness and wear resistance. The elevated carbon content (~0.97%) combined with cobalt and molybdenum additions creates a material suited to demanding cutting, forming, and high-stress applications where both corrosion resistance and exceptional strength are required. This variant occupies a niche between standard martensitic stainless steels and tool steels, offering superior hardness while maintaining the corrosion resistance benefits of the 14Cr family—making it the choice when standard austenitic or lower-carbon martensitic grades cannot survive abrasive or corrosive service.
