Super Duplex Steel Bars generally consist of Chromium (24–26%), Nickel (6–8%), Molybdenum (3–5%), Nitrogen (0.2–0.3%), and Copper (0.5–1.0%), with Iron as the balance and Carbon content ≤0.03%. These bars possess excellent mechanical properties with tensile strength of 750–800 MPa, yield strength of 550 MPa, and elongation of about 25%. Their physical properties are a density of 7.8 g/cm³ and a melting point of about 1350°C. The alloy possesses excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in chloride-enriched environments, and thus it is applicable in heavy-duty, corrosive, and high-pressure applications.
