Abstract

U.S.S. 18-8 Cb-Ta is an austenitic chromium-nickel type stainless steel with the carbon stabilized by columbium-tantalum for welding and elevated temperature service. This type is useful when the weldment is not annealed after welding. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness, creep, and fatigue. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: SS-42. Producer or source: United States Steel Corporation.
