This high-carbon variant of 347 stainless steel is known for its improved creep resistance, strength, and oxidation stability when exposed to elevated temperatures. Victor guarantees that each sheet and plate adheres to international quality standards, ensuring precise dimensions, a smooth finish, and remarkable durability. Thanks to their excellent thermal stability and resistance to intergranular corrosion, Stainless Steel 347H Sheets and Plates find extensive use in chemical processing, petroleum refining, power generation, and heat exchanger applications.
Stainless Steel 347H is an austenitic chromium-nickel steel that’s stabilized with niobium (columbium) and features a higher carbon content (0.04–0.10%) compared to 347. It generally contains 17–19% chromium, 9–13% nickel, and small amounts of niobium for carbide stabilization. This alloy boasts a tensile strength ranging from 515–700 MPa, a yield strength of about 205 MPa, and an elongation of 40%. 347H is known for its excellent creep and stress rupture resistance, outstanding oxidation resistance up to 870°C (1600°F), and good weldability, making it perfect for high-pressure and high-temperature structural and mechanical applications.
