U.S.S. COR-TEN is a corrosion resistant high-strength steel of low alloy content, intended primarily for weight reduction, or longer life, by means of greater strength and enhanced atmospheric corrosion resistance in applications involving fabrication by forming and welding. This datasheet provides information on composition, physical properties, elasticity, tensile properties, and compressive and shear strength as well as fracture toughness and fatigue. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SA-17. Producer or source: United States Steel Corporation.
