12Cr-8Ni Austenitic Stainless

metal

12Cr-8Ni is a precipitation-hardening austenitic stainless steel designed to achieve high strength while maintaining the corrosion resistance and toughness characteristic of austenitic stainless alloys. The addition of aluminum, tungsten, and titanium enables strengthening through age-hardening treatments, making this alloy suitable for applications requiring both corrosion resistance and elevated mechanical performance in moderately aggressive environments. This material bridges the gap between standard austenitic stainless steels (like 304/316) and martensitic precipitation-hardening grades, offering a balance of formability, toughness, and strength for aerospace, chemical processing, and fastener applications.

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.
