SS 316/316L includes about 16-18% chromium, 10-14% nickel, 2-3% molybdenum, with 316L containing ≤0.03% carbon. This lowers carbide precipitation during welding. SS 316 welded pipes have a tensile strength of about 515 MPa, yield strength of around 205 MPa, and an elongation of 35%. 316L has slightly lower strength but better weldability. These pipes have excellent resistance to chlorides, acids, and brine. Their ductility, impact strength, and resistance to pitting make them suitable for high-pressure and temperature services in corrosive environments, providing reliable performance throughout their operational life.
