Stainless Steel 348 is composed primarily of chromium (17–20%), nickel (8–11%), and niobium (columbium), which stabilizes the steel against chromium carbide formation. It offers a tensile strength of approximately 550–600 MPa and yield strength of around 240–290 MPa, with good ductility and excellent weldability. The alloy is resistant to intergranular corrosion and maintains mechanical integrity in high-temperature environments. These properties make SS 348 pipe fittings suitable for prolonged exposure to elevated temperatures and aggressive media, ensuring structural stability and corrosion resistance in various industrial piping systems
