A precipitation-hardened austenitic stainless steel with 13% chromium, 8% nickel, and significant aluminum (2.15%) addition for age-hardening capability. This variant bridges conventional austenitic stainless steels and maraging-class alloys, delivering enhanced strength through precipitate formation while retaining austenitic corrosion resistance and toughness. Industrial applications favor aerospace and high-performance mechanical components where elevated strength at moderate temperatures is required without sacrificing corrosion resistance or fabricability.
