Cor-Ten steel is a proprietary brand name for corrosion resistant steels that were developed by the United States Steel company many years ago. Nippon Steel is now licensed to produce this steel. The comparison of Cor-Ten to the ASTM grades is loosely stated as Cor-Ten A is equivalent to ASTM A242, and Cor-Ten B is equivalent to ASTM A588 Grade A. Both meet or exceed the requirements of ASTM A606 Type 4.
