15Cr-8Ni Austenitic Stainless

metal

15Cr-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.

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.
