13Cr-8Ni Austenitic Stainless (var. 16)

A precipitation-hardened austenitic stainless steel combining 13% chromium and 8% nickel with significant aluminum and molybdenum content to achieve high strength through age-hardening. This variant belongs to the martensitic-austenitic family and is engineered for applications demanding both corrosion resistance and elevated strength at moderate temperatures, bridging the gap between standard austenitic stainless steels and martensitic grades. The composition—particularly the aluminum and molybdenum additions—enables strength development via precipitation reactions while maintaining austenitic phase stability and ductility superior to fully martensitic alternatives.
