Duplex Steel Forged Fittings are made from a combination of austenitic and ferritic stainless steels, typically containing 22-25% chromium, 4.5-6.5% nickel, 3-5% molybdenum, along with small amounts of nitrogen, manganese, and silicon. This unique composition provides superior corrosion resistance, particularly in chloride-rich environments, and enhances strength. Mechanically, these fittings offer a tensile strength of 620-750 MPa, yield strength of 450 MPa, and approximately 25% elongation. They also exhibit excellent fatigue resistance and high toughness, making them ideal for high-pressure and corrosive applications in various industries.
