13Cr Martensitic Stainless

metal

13Cr martensitic stainless steel is an iron-based alloy with approximately 13% chromium, enhanced by significant molybdenum and cobalt additions, designed to achieve high strength through martensitic hardening. This composition targets demanding applications requiring a combination of corrosion resistance and exceptional hardness; the elevated carbon and nitrogen levels, along with cobalt strengthening, position it for aerospace and high-performance industrial components where traditional stainless steels fall short. Compared to standard 13Cr martensitic grades, the cobalt boost and molybdenum content increase both hardening capability and corrosion resistance, making it suitable for aggressive service environments where wear and chemical attack occur simultaneously.

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.
