Super Duplex Steel is an ultra-high alloyed stainless steel with a balanced microstructure of austenite and ferrite, providing high strength and corrosion resistance. Its composition is generally 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and trace levels of nitrogen and manganese. The alloy provides excellent mechanical properties such as tensile strength of about 750–850 MPa, yield strength of about 550 MPa, and elongation of 25%. Super Duplex Pipe Fittings provide excellent resistance to chloride-induced stress corrosion cracking, pitting, and general corrosion and are ideal for very corrosive and high-pressure conditions in all major industrial sectors.
