Carbon steel square tubes are more widely used. The main requirement of the chemical composition of carbon steel square tube is the content of carbon. Carbon steel square tube characteristics and scope of application: C20C (1.0411) high-quality carbon structural steel is slightly higher in strength than No. 15 steel. C20C (1.0411) has high cold deformation plasticity, and machinability is better in cold drawn or normalized state than in annealed state.

The square tube material is generally plain carbon steel square tube. Common carbon steel is divided into: Q195, Q215, Q235, SS400, 20# steel, 45# steel, etc.; most carbon steel square tubes are unpacked, flattened, crimped, welded to form round tubes, and then rolled into square tubes The tube is then cut to the desired length.
