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

metal

13Cr-8Ni is a precipitation-hardening austenitic stainless steel combining moderate chromium content (13.3%) with nickel and significant aluminum (2.18%) to enable age-hardening strengthening. This material is engineered for high-strength applications requiring corrosion resistance and dimensional stability, sitting in the intermediate performance band between standard austenitic grades (like 304) and premium super-austenitic or duplex stainless steels. It is used in aerospace fasteners, high-pressure hydraulic components, and chemical processing equipment where both corrosion resistance and elevated mechanical properties are needed without sacrificing ductility.

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.
