Duplex Steel Flanges 2205 are crafted from a unique dual-phase microstructure that combines austenitic and ferritic stainless steel, typically featuring 22% chromium, 5–6% nickel, 3% molybdenum, and a touch of nitrogen, all while keeping carbon content low. This special composition provides outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, these flanges offer impressive tensile strength (620–880 MPa), yield strength (450–550 MPa), along with superior toughness and ductility. The 2205 grade guarantees structural integrity and durability, making it perfect for high-pressure, high-temperature, and corrosive industrial applications.
