So, what exactly is Stainless Steel 348? It’s an austenitic stainless steel alloy that typically contains around 18% chromium, 8–11% nickel, along with small amounts of niobium (columbium) and tantalum. The addition of niobium helps stabilize the alloy against carbide precipitation, which boosts its resistance to intergranular corrosion, especially when exposed to high temperatures for extended periods. On the mechanical side, Stainless Steel 348 boasts a tensile strength ranging from about 515 to 620 MPa and a yield strength close to 205 MPa, along with excellent creep and oxidation resistance up to 900°C.
