13Cr-8Ni Austenitic Stainless (var. 15)

metal

13Cr-8Ni is a precipitation-hardening austenitic stainless steel variant combining high chromium and nickel content with aluminum and molybdenum additions to develop exceptional strength through age-hardening. This material bridges conventional austenitic stainless steels and martensitic grades, offering corrosion resistance alongside elevated-temperature strength without sacrificing ductility. It is widely deployed in aerospace, oil & gas, and power generation where components must resist corrosive environments while maintaining structural integrity under thermal cycling or sustained loading—notably in landing gear, fasteners, valve bodies, and steam turbine components where both strength and environmental durability are critical.

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.
