USS COR-TEN A, the original COR-TEN Steel composition (see U.S.S. COR-TEN, Alloy Digest SA-17, April 1954), has 5 to 8 times the atmospheric corrosion resistance of structural carbon steel and a minimum yield point of 50,000 psi in sections through 1/2-inch thick. This datasheet provides information on composition, physical properties, elasticity, tensile properties, and compressive and shear strength as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SA-283. Producer or source: United States Steel Corporation.
