15Cr-1Ni Duplex Stainless is a ferrite-austenite two-phase stainless steel combining moderate chromium content with low nickel addition, designed for corrosion resistance and structural strength in moderately aggressive environments. This material balances cost efficiency against full austenitic stainless steels by reducing nickel demand while maintaining duplex phase benefits, making it suitable for applications requiring good corrosion resistance without premium alloying costs. Its composition suggests use in industrial equipment, piping systems, and equipment exposed to mildly corrosive media where standard ferritic stainless steels would be insufficient but full duplex or austenitic grades are economically unjustified.
