13Cr-8Ni Austenitic Stainless (var. 8)
metal13Cr-8Ni is a precipitation-hardening austenitic stainless steel combining moderate chromium content (13.4%) with nickel (7.91%) and significant aluminum (2.11%) to enable age-hardening strengthening. This variant bridges martensitic and austenitic stainless families, offering corrosion resistance alongside hardening capacity—making it suitable for applications demanding both environmental durability and high strength without requiring full austenitic softness. It is commonly selected for aerospace fasteners, turbine components, and corrosive-wear environments where conventional austenitic grades would be too soft or where martensitic brittleness is undesirable.
