Stainless Steel 348H is a columbium/tantalum-stabilized austenitic stainless steel, closely related to grade 347 but with a higher carbon content for better creep resistance at high temperatures. Its typical composition includes 17-19% chromium, 9-13% nickel, less than 0.10% carbon, plus columbium/tantalum for stabilization. This alloy resists intergranular corrosion and carbide precipitation during welding and thermal cycling. Its mechanical properties include tensile strength of about 515 MPa, yield strength of approximately 205 MPa, elongation of at least 40%, and excellent stress-rupture and creep resistance. These qualities make 348H suitable for long-term high-temperature service in aggressive environments.
