Supply Wholesale China hot rolled cold rolled steel pipe
The main differences between hot rolled steel pipe and cold rolled steel pipe are:
1, Cold rolled steel pipe allow local buckling of the section, so that the bearing capacity of the member after buckling can be fully used; hot-rolled steel pipes do not allow local buckling of the section.
2.The causes of residual stress in hot rolled steel tube and cold rolled steel tube are different, so the distribution on the cross-section is also very different. The residual stress distribution is thin film type.
3.The free torsional stiffness of hot rolled steel pipes is higher than that of cold rolled steel pipes, so the torsion resistance of hot rolled steel pipe is better than cold-rolled steel pipe.
