Super Duplex Steel Pipe Fittings are primarily made up of iron, featuring 24–26% chromium, 6–8% nickel, 3–5% molybdenum, along with trace amounts of nitrogen and manganese. This unique blend creates a balanced duplex microstructure of austenite and ferrite, giving these fittings impressive mechanical properties. They offer a tensile strength ranging from 850–1000 MPa, yield strength between 550–700 MPa, and an elongation of 25–30%. With superior hardness, toughness, and fatigue resistance, these fittings are perfectly suited for high-pressure, high-temperature, and highly corrosive environments, ensuring they maintain structural integrity and reliability over time.
