Typically made from a blend of high chromium, nickel, molybdenum, and nitrogen, Super Duplex Steel Tube Fittings offer remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking. The unique duplex microstructure, which combines both austenitic and ferritic phases, boosts tensile strength, fatigue resistance, and toughness. These fittings maintain their mechanical stability even under high-pressure and high-temperature conditions. With a high PREN value, they provide excellent corrosion protection in environments rich in chlorides. Their low thermal expansion, good weldability, and outstanding wear resistance ensure long-term mechanical integrity in demanding industrial applications.
