14Cr Martensitic Stainless (var. 8)

metal

14Cr 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.

Industry-Specific

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.
