Stainless Steel 347 is an austenitic stainless steel alloy that contains about 17–19% chromium and 9–13% nickel, with niobium (columbium) added to prevent carbide precipitation. This clever stabilization boosts resistance to intergranular corrosion, particularly after welding or extended heat exposure. The alloy showcases a tensile strength ranging from 515 to 620 MPa and a yield strength close to 205 MPa, along with excellent oxidation resistance up to 900°C and solid mechanical stability.
