12Cr-9Ni Austenitic Stainless

metal

12Cr-9Ni is a modified austenitic stainless steel that combines chromium and nickel additions with tungsten, aluminum, and vanadium to enhance strength and wear resistance beyond conventional 300-series stainless grades. This composition positions it for demanding applications requiring both corrosion resistance and elevated hardness—typical of specialized tooling, high-stress fasteners, or components operating in mildly corrosive environments where conventional austenitic grades would be insufficient. The alloy represents an engineered middle ground between standard austenitic stainless steels and martensitic hardened variants, making it relevant where engineers need austenite stability without sacrificing load-bearing capacity.

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.
