Duplex Steel Forgings (usually UNS S31803 / S32205) have about Cr 21–23%, Ni 4.5–6.5%, Mo 2.5–3.5%, Mn <2%, Si <1%, N 0.14–0.2%, C <0.03%, Fe balance. They provide tensile strength of 620–880 MPa, yield strength ≥450 MPa, and elongation 25–30%, providing great mechanical longevity. The density is around 7.8 g/cm³, and melting point ~1350–1400°C. Duplex steel provides better resistance against stress corrosion cracking, pitting, and crevice corrosion. It also possesses good weldability and high thermal conductivity, thus applicable for use in highly corrosive and structurally stressful conditions.

Duplex Steel Forgings have widespread application in the oil and gas sector, especially in subsea and offshore platforms where the need for high strength and corrosion resistance is paramount. They are utilized in heat exchangers, valves, flanges, and pump parts in the petrochemical and chemical industries. Their corrosion resistance against chloride makes them perfect for marine use. In power generation, they perform well under conditions of high temperature and high pressure. They are also employed in construction materials, paper and pulp treatment, and building structures in constructions that need to be durable and resistant to adverse conditions. Their equilibrated properties qualify them for sophisticated engineering problems.
