11Cr-7Ni-3.3Mo Stainless (var. 2)
metal11Cr-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.
