1. Cold-rolled steel allows partial buckling of the section so that the bearing capacity of the bar after buckling can be fully utilized and the hot-rolled steel does not allow local buckling of the section. 2. The causes of residual stresses in hot-rolled and cold-rolled steels are different so the distribution on the cross-section is also
