13Cr Martensitic Stainless (var. 11)

metal

13Cr Martensitic Stainless Steel (variant 11) is a high-carbon, cobalt-reinforced martensitic stainless steel designed for demanding applications requiring exceptional hardness and wear resistance combined with corrosion resistance. This variant is heavily alloyed with cobalt (~14 wt%), molybdenum, and vanadium—additions typical of premium tool steels and specialty cutlery grades—making it suitable for high-performance cutting tools, precision bearings, and corrosive environments where both toughness and edge retention are critical. Compared to standard 13Cr stainless grades (like 420 or 440C), this composition prioritizes hardness and thermal fatigue resistance, positioning it as a niche material for aerospace, medical instrumentation, and advanced manufacturing tooling where cost justifies superior performance.

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.
