Stainless Steel 348H Flanges are primarily made up of chromium (18–20%), nickel (10–13%), and niobium, which acts as a stabilizing element, featuring a higher carbon content than 347H to boost high-temperature strength. This unique composition grants them outstanding resistance to intergranular corrosion, oxidation, and scaling, especially in high-temperature settings. On the mechanical side, 348H flanges provide impressive tensile strength, excellent creep resistance, and remarkable fatigue performance even under elevated temperatures. Their sturdy design guarantees structural integrity and durability, making them perfect for critical piping systems that face extreme heat and pressure.
