Product parameters

1020 is a high-quality carbon structural steel, toughness, plasticity, weldability are good, rarely quenched, no temper brittleness. Cold deformation plastic high, generally for bending, calendering, bending and hammer arch and other processing.
SAE1045/1045 Properties and applications: high strength medium carbon tempered steel, with certain plasticity and toughness, high strength, good machinability, the use of tempered treatment can obtain good comprehensive mechanical properties

Hot rolled seamless steel pipe production process:

Tube blank → heating → perforation → three-high skew rolling and continuous rolling → Stripping → sizing → Cooling → straightening → hydraulic test → marking → lever effect seamless steel pipe in storage will be detected.

Cold-drawn seamless steel pipe production process:

Tube blank → heating → perforating → heading → annealing → pickling → oiling → multi-pass cold drawing → Tube blank → Heat treatment → straightening → hydraulic test → marking → storage. The wall thickness of cold-drawn seamless steel pipe is better than that of hot-rolled seamless steel pipe, and the surface roughness is also some.
