13Cr-2Ni Duplex Stainless
metal13Cr-2Ni is a lean duplex stainless steel combining ferritic and austenitic phases to balance strength, corrosion resistance, and cost compared to standard austenitic grades. It is widely used in oil and gas pipelines, chemical processing equipment, and marine applications where moderate corrosion resistance and superior strength-to-weight ratio are required without the cost premium of higher-alloy duplex or super-duplex stainless steels. Engineers select this material when operating pressures and temperatures exceed what standard austenitic stainless steels (like 304/316) can safely handle, yet full-strength duplex (like 2205) is economically unjustified.

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.
