Typically, Duplex Steel Pipe Fittings consist of 22–25% chromium, 4–6% nickel, 3–5% molybdenum, and trace amounts of nitrogen, manganese, silicon, and carbon. This specific blend ensures exceptional corrosion resistance in environments rich in chlorides and oxidizing agents while preserving mechanical strength and toughness. The dual-phase structure enhances ductility, weldability, and thermal stability, enabling these fittings to perform reliably under high-pressure, high-temperature, and chemically aggressive conditions.
