Stainless Steel 348 Pipes are a stabilized austenitic stainless steel, primarily composed of 18–20% chromium, 9–13% nickel, and small additions of niobium to prevent carbide precipitation. This composition enhances resistance to intergranular corrosion and maintains mechanical strength at high temperatures. They offer a tensile strength of 515–750 MPa and a yield strength of 205–450 MPa, with a density of approximately 8.0 g/cm³. Stainless Steel 348 Pipes resist scaling, oxidation, and stress corrosion, making them ideal for applications where both high-temperature stability and corrosion resistance are critical.
