Super Duplex Steel Flanges typically contain Chromium (24–26%), Nickel (6–8%), Molybdenum (3–5%), Nitrogen (0.2–0.3%), and Copper (0.5–1.0%) with Iron as base and Carbon content ≤0.03%. These flanges have better mechanical properties with tensile strength of 750–800 MPa, yield strength of 550 MPa, and elongation of about 25%. Physically, they have a density of 7.8 g/cm³ and a melting point of about 1350°C. These properties render Super Duplex flanges very resistant to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride-containing and aggressive industrial environments.
