13Cr-8Ni Austenitic Stainless (var. 17)
metal13Cr-8Ni is a precipitation-hardening austenitic stainless steel combining moderate chromium content (13.3%) with nickel and significant aluminum (2.11%) to enable age-hardening strengthening. This variant is engineered for applications demanding both corrosion resistance and high strength-to-weight performance, positioning it between conventional austenitic stainless steels and martensitic precipitation-hardeners; the aluminum addition enables precipitation hardening while maintaining austenitic stability, making it suitable for demanding aerospace and industrial component applications where thermal stability and fatigue resistance under cyclic loading are critical.
