Stainless Steel 347H Rectangular Bars are mainly made up of iron, with 17–19% chromium, 9–13% nickel, and trace amounts of niobium and carbon. The increased carbon content compared to standard 347 steel boosts its strength at high temperatures, while niobium helps stabilize the structure, preventing intergranular corrosion. In terms of mechanical properties, 347H bars showcase outstanding tensile strength, hardness, ductility, and toughness. They retain their characteristics even under high thermal stress, making them perfect for welded structures and high-temperature applications. These features ensure consistent performance in challenging industrial settings.
