Our Stainless Steel 348H Pipe Fittings are crafted from a niobium-stabilized austenitic stainless steel alloy, featuring a higher carbon content to enhance strength at elevated temperatures. The addition of niobium (or columbium) improves resistance to carbide precipitation during welding and exposure to high heat, which helps reduce the risk of intergranular corrosion. These fittings maintain excellent tensile and yield strength, along with oxidation and creep resistance at temperatures exceeding 800 °C, all while preserving ductility and toughness during thermal cycling.
