15Cr-8Ni Austenitic Stainless
metal15Cr-8Ni is a precipitation-hardened austenitic stainless steel containing significant cobalt and aluminum, designed to achieve high strength while maintaining corrosion resistance typical of chromium-nickel stainless alloys. It is used primarily in aerospace and high-temperature structural applications where combined corrosion resistance, strength, and thermal stability are required—particularly in jet engine components, fasteners, and pressure vessels operating in demanding environments. The cobalt and aluminum additions enable precipitation hardening, making this alloy notably stronger than conventional austenitic stainless steels, though it trades some ductility for increased load-carrying capacity in high-stress applications.
