Duplex Steel Pipe Fittings are composed of a dual-phase microstructure of austenite and ferrite, typically containing 22-25% chromium, 4-7% nickel, and 2-4% molybdenum, with nitrogen for added strength and corrosion resistance. These fittings offer excellent mechanical properties, including a tensile strength of 620-850 MPa, yield strength of 450-600 MPa, and elongation of about 25%. They exhibit high resistance to pitting, crevice corrosion, and stress corrosion cracking, making them durable in harsh environments. Their superior weldability and toughness make them ideal for industrial and marine applications.
