Super Duplex BSP/NPT Fittings are crafted from Super Duplex stainless steel (UNS S32750/S32760), an alloy composed mainly of chromium, nickel, molybdenum, and nitrogen. This composition provides superior resistance to pitting, crevice corrosion, and stress corrosion cracking. Mechanically, these fittings exhibit high tensile strength, excellent toughness, and outstanding fatigue resistance even at elevated temperatures. With a balanced microstructure of austenite and ferrite, Super Duplex ensures enhanced hardness and weldability, making it ideal for critical piping systems exposed to aggressive environments and high-pressure applications.
