Stainless Steel 348 is a niobium-stabilized austenitic stainless steel alloy, typically composed of 17–20% chromium, 9–13% nickel, and trace amounts of niobium (columbium). While it shares similarities with 347, it’s specifically engineered for better weldability and enhanced resistance to intergranular corrosion. This alloy boasts a tensile strength of about 515 MPa and a yield strength of roughly 205 MPa. It also maintains impressive mechanical properties at elevated temperatures, offering excellent resistance to creep and stress rupture, along with superior oxidation and scaling resistance when exposed to heat.
