A500 Grades B and C Structural Tubing Steel description
ASTM A500 is a standard specification developed by the American Society for Testing and Materials (now known as ASTM International) for cold-formed welded and seamless carbon steel structural tubing. This standard stipulates a series of technical indicators including the size, shape, weight, chemical composition, mechanical properties, manufacturing method, and inspection requirements of the steel pipes. A500 Grades B and C are two different strength levels within this standard. A500 GRB and GRC welded pipes can be produced by bending carbon steel plates or strips into the desired shape through cold-forming processes followed by welding. During the manufacturing process, process parameters need to be strictly controlled to ensure the dimensional accuracy and internal quality of the steel pipes.
