13Cr-1Ni Duplex Stainless

metal

13Cr-1Ni duplex stainless steel is a lean duplex stainless steel combining a ferritic-austenitic microstructure with 13% chromium, moderate nickel, and molybdenum additions for corrosion resistance and strength. This alloy family is widely used in oil and gas production, desalination plants, and chemical processing where chloride environments would attack conventional austenitic stainless steels, offering superior pitting resistance and stress corrosion cracking performance at a lower cost than super-duplex grades. Engineers select duplex stainless steels when they need the strength advantages of ferrite with the toughness of austenite, plus resistance to seawater and industrial corrosion—making them ideal for pressure vessels, piping, and subsea components where both mechanical performance and environmental durability are critical.

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.
