Patinax 355P is a weathering steel that due to its chemical composition, when utilized unprotected, exhibits resistance to atmospheric corrosion over unalloyed steels. Patinax 355P has increased phosphorus content for improved weather resistance compared with Patinax 355 (Alloy Digest SA-803, October 2017). This datasheet provides information on composition and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, machining, and joining. Filing Code: SA-805. Producer or source: ThyssenKrupp Steel Europe AG.

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.
