12Cr-9Ni Austenitic Stainless (var. 3)

metal

12Cr-9Ni austenitic stainless steel is a chromium-nickel ferritic-austenitic variant engineered for enhanced strength and corrosion resistance through molybdenum and titanium additions. It bridges standard austenitic stainless grades (like 304/316) and duplex stainless steels, offering improved mechanical performance while maintaining workability. Select this material when you need better strength-to-weight performance than commodity austenitic grades in corrosive environments, particularly where chloride pitting resistance and thermal fatigue matter—such as chemical processing equipment, high-pressure piping, or heat exchanger tubing in aggressive media.

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.
