Duplex steel fittings, including BSP and NPT types, typically contain about 22% chromium, 5% nickel, and 3% molybdenum for improved corrosion resistance and strength Mechanical properties include high tensile strength (up to 550 MPa), good ductility, and good fatigue resistance. These fittings are advantageous due to their ability to withstand harsh environments, making them ideal for oil and gas, chemical and marine applications Their high resistance to pitting and stress corrosion cracking ensures a long and capable life reliability, ultimately reducing maintenance costs and improving system performance.
