Duplex stainless steel has the advantages of both ferritic stainless steel and austenitic stainless steel: austenitic stainless steel reduces the brittleness, maintains excellent toughness and weldability; ferritic stainless steel improves the yield strength, intergranular corrosion resistance and chloride stress corrosion resistance.
The lower nickel and molybdenum content of the Duplex Stainless Steels as compared to the austenitic grades with similar corrosion resistance, gives the Duplex grades a lower cost.
