13Cr-8Ni Austenitic Stainless (var. 3)

metal

13Cr-8Ni is a precipitation-hardening austenitic stainless steel that combines chromium and nickel for corrosion resistance with aluminum and molybdenum additions to enable age-hardening strengthening. This variant is engineered for applications requiring both high strength and corrosion resistance, positioning it between standard austenitic stainless steels (which rely on work-hardening) and martensitic precipitation-hardening grades. It is commonly used in aerospace fasteners, chemical processing equipment, and high-performance pump/compressor components where engineers need superior mechanical properties without sacrificing corrosion performance in moderately aggressive environments.

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.
