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.

The Duplex Steel Pipe Fittings are crafted from a unique dual-phase stainless steel alloy that merges austenitic and ferritic microstructures. This typically includes about 22% chromium, 5-6% nickel, and 3% molybdenum. This special blend gives them outstanding resistance to issues like chloride-induced stress corrosion cracking, pitting, and crevice corrosion, all while maintaining excellent mechanical properties. Generally, duplex stainless steel fittings showcase tensile strengths around 620 MPa and improved toughness, making them perfect for high-pressure and corrosive situations.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
