Stainless Steel 347/347H Sheets and Plates are stabilized austenitic stainless steels that include chromium, nickel, and columbium (niobium), with an extra boost of carbon in 347H for improved high-temperature strength. Typically, their composition features 17–19% chromium and 9–13% nickel, which ensures remarkable resistance to intergranular corrosion and oxidation. On the mechanical side, these sheets and plates boast high tensile strength, excellent creep resistance, and good toughness, even when the heat is on. The addition of niobium enhances stability, preventing carbide precipitation and keeping structural integrity intact under thermal stress.
