When it comes to Composition and Mechanical Properties, Stainless Steel 347H is a high-carbon variant of 347, stabilized with niobium (columbium), which gives it remarkable resistance to intergranular corrosion. Its makeup features chromium (17–19%), nickel (9–13%), carbon (0.04–0.10%), and niobium, along with trace elements of manganese, silicon, phosphorus, and sulfur. The tensile strength of 347H round bars is about 515 MPa, with a yield strength of around 205 MPa, and they exhibit good resistance to creep and stress rupture. This alloy is particularly well-suited for high-temperature applications due to its enhanced mechanical properties, oxidation resistance, and structural stability when exposed to prolonged heat.
