Product details

The main difference between hot rolled stainless steel pipe and cold rolled stainless steel pipe

1. The cold-rolled stainless steel pipe allows local buckling of the section, so that the bearing capacity of the rod after buckling can be fully used, but the hot-rolled stainless steel pipe does not allow local buckling of the section.

2. The causes of residual stress in hot-rolled steel and cold-rolled steel are different, so the distribution on the cross section is also very different. The residual stress distribution on the section of cold-formed thin-wall steel is curved, while the residual stress distribution on the section of hot-tied or welded steel is thin film.

3, the free torsional rigidity of hot-rolled steel is higher than that of cold-rolled steel, so the torsional resistance of hot-rolled stainless steel pipe is better than that of cold-rolled steel.
