Super Duplex Steel Flanges are crafted from high-alloy stainless steel that boasts elevated levels of chromium, nickel, molybdenum, and nitrogen, resulting in a well-balanced austenitic and ferritic microstructure. This unique composition grants them remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, these flanges showcase exceptional yield and tensile strength, outstanding fatigue resistance, and good ductility. They also provide superior impact toughness, a high load-bearing capacity, and reliable performance even in extreme temperatures, pressures, and aggressive chloride-rich environments.
