13Cr Martensitic Stainless (var. 15)

metal

13Cr Martensitic Stainless Steel (variant 15) is a hardened chromium-bearing iron alloy strengthened through martensitic transformation, with notable alloying additions of cobalt, molybdenum, and vanadium that enhance hardness and wear resistance. This material is primarily used in high-strength applications requiring corrosion resistance combined with superior hardness, such as precision cutting tools, turbine blades, and wear-critical components in aerospace and power generation. Engineers select this variant over standard martensitic stainless grades when extreme hardness and edge retention are essential, accepting lower ductility in exchange for exceptional performance in demanding mechanical and thermal environments.

Quality & Standards

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.
