The difference between hot rolled and cold rolled stainless steel angle bar?

Many people don’t know what is the difference between hot-rolled and cold-rolled. As a professional stainless steel angle bar manufacturer, the staff will come to reveal this doubt for everyone.

The main difference between hot rolled stainless steel angle bar and cold rolled stainless steel angle bar are: 　

　1. The cold-rolled steel allows local buckling of the section, so that the bearing capacity of the bar after buckling can be fully utilized; while the hot-rolled steel does not allow local buckling of the section. 　

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

　3. The free torsional stiffness of hot-rolled steel is higher than that of cold-rolled steel, so the torsion resistance of hot-rolled steel is better than that of cold-rolled steel. 　　

 

Before purchasing stainless steel angle bar, it is necessary to hand over the basic product performance, model and price range, so as to prevent everyone from being deceived.
