12Cr-10Ni Austenitic Stainless

metal

12Cr-10Ni is a precipitation-hardened austenitic stainless steel strengthened by intermetallic phases (notably aluminum and cobalt compounds), designed to deliver high strength while retaining the corrosion resistance of the austenitic family. It is used in demanding aerospace, power generation, and oil & gas applications where elevated-temperature strength and resistance to corrosion or oxidation are required simultaneously—environments where conventional 300-series austenitic stainless steels would be too soft, but martensitic or ferritic stainless steels lack adequate toughness or corrosion performance. The addition of refractory elements (titanium, molybdenum) and precipitation hardeners (cobalt, aluminum) makes this alloy a bridge between commodity austenitic grades and superalloy territory, offering a practical middle ground for intermediate-temperature service.

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.
