Stainless steel 348H bars are a more carbon version of alloy 348, designed for increased creep resistance and superior thermal properties. It is generally used in applications that require exposure to high temperatures for extended periods of time. The composition of 348H contains 17-19% chromium, 9-13% nickel, columbium (niobium) and trace amounts of tantalum, which stabilizes the alloy and prevents carbide precipitation These properties make the alloy resistant to intergranular corrosion and oxidation face Stainless Steel 348H Generally Aerospace, Medical , used in inside nuclear reactors, where Its excellent mechanical properties and thermal resistance ensure reliable operation in harsh environments
