Iron, chromium (17–20%), nickel (8–11%), and columbium (niobium), which stabilises the alloy against carbide precipitation, make up stainless steel 348 flanges. They might also have trace amounts of silicon, manganese, and carbon. Particularly after welding, this alloy provides good resistance to intergranular corrosion. Tensile strength of roughly 515 MPa, yield strength of roughly 205 MPa, and elongation of roughly 35% are examples of mechanical properties. Stainless Steel 348 is appropriate for high-stress, high-heat applications because it maintains exceptional mechanical stability and oxidation resistance at high temperatures.
