11Cr-7Ni-3.3Mo Stainless (var. 2)

metal

11Cr-7Ni-3.3Mo is a martensitic stainless steel with cobalt addition, formulated to deliver high strength and hardness while maintaining corrosion resistance in moderately aggressive environments. The composition—dominated by iron with controlled chromium, nickel, and molybdenum levels plus ~10% cobalt—positions this as a precipitation-hardenable or age-hardened variant designed for applications demanding both wear resistance and structural integrity. This steel is typically selected for critical components in aerospace, medical devices, and industrial tooling where fatigue performance and corrosion resistance must be balanced against cost and machinability constraints.

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.
