Stainless Steel 348 and 348H are columbium-stabilized austenitic stainless steel grades that offer remarkable resistance to intergranular corrosion, especially after welding and during prolonged exposure to high temperatures. These alloys boast excellent oxidation resistance, tensile strength, and creep resistance. The 348H variant, which has a higher carbon content, provides enhanced mechanical strength and stability at elevated temperatures. Both grades are known for their excellent weldability, ductility, and toughness, ensuring they maintain structural integrity and resist corrosion even in harsh environments and high-stress applications.
