Duplex Steel Plates and Sheets are usually produced from UNS S32205 or S31803 grades with Chromium (Cr) 21–23%, Nickel (Ni) 4.5–6.5%, Molybdenum (Mo) 2.5–3.5%, Nitrogen (N) 0.14–0.2%, Manganese (Mn) ≤2%, and Carbon (C) ≤0.03%. These alloys possess remarkable mechanical properties with tensile strength of 620–880 MPa, yield strength of ≥450 MPa, and elongation of 25–30%. They have a density of approximately 7.8 g/cm³ and a melting point range of 1350–1450°C. Duplex steel is a combination of ferritic and austenitic steels’ strength, with excellent resistance to pitting, crevice corrosion, and stress corrosion cracking.

Duplex Steel Sheet and Plates are used in high–strength and corrosion-resistant requirement industries on a large scale. Typical uses are pressure vessels, heat exchangers, desalination plants, chemical tanks, marine equipment, and offshore structures. They are particularly well-suited to chlorides and aggressive chemicals environments and therefore find particular use in the oil & gas and petrochemical applications. Their better mechanical strength provides weight savings in structural applications, while their corrosion resistance prolongs service life in aggressive environments. They are also used in pulp and paper processing, bridges, and architectural elements where both strength and appearance are significant.
