13Cr Martensitic Stainless (var. 26)

metal

13Cr Martensitic Stainless Steel (variant 26) is a high-carbon, cobalt-strengthened martensitic stainless steel designed for applications demanding exceptional hardness and wear resistance combined with corrosion resistance. The elevated cobalt content (~16%) and moderate molybdenum addition create a precipitation-hardening system that delivers high strength while retaining reasonable toughness, making it suitable for demanding aerospace, tooling, and high-performance industrial applications where conventional 13Cr grades fall short. This variant represents an engineering solution for engineers who need stainless steel's corrosion benefits without sacrificing the hardness and fatigue performance typically associated with tool steels.

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.
