Super Duplex Steel Forged Fittings are made up of 24–26% chromium, 6–8% nickel, 3–5% molybdenum, along with tungsten, nitrogen, and low carbon content. This carefully balanced composition provides excellent resistance to pitting, crevice corrosion, and stress corrosion cracking caused by chlorides. On the mechanical side, they boast a tensile strength of about 750–800 MPa and a yield strength of roughly 550 MPa, along with impressive impact toughness even in freezing conditions. Their unique duplex microstructure, which combines austenite and ferrite, enhances fatigue strength, weldability, and long-lasting durability, making them incredibly reliable for critical applications under high pressure and corrosive conditions.
