Cold Rolled Black Annealed Steel Pipe 19mm 20mm

Short Description:

Cold Rolled Steel Pipes have square hollow section and circular section (round hollow section). The material is cold rolled carbon steel strap with wall thickness 0.6mm to 2.0mm. When cold-rolled steel strap is heated to the annealing temperature, the surface color will turn black due to high temperature contact with air, which is called black stripping. The physical properties become soft, which is convenient for further welding to make steel pipes. The common hardness is 57HRB, and it can also be reduced to different hardness as needed.
