The difference between cold-rolled and hot rolled stainless steel angel bar

What is the difference between cold rolling stainless steel angel bar and hot rolled stainless steel angel bar? Cold-rolled stainless steel angel bar and hot rolled stainless steel angel bar is respectively using two different rolling cold rolled and hot rolled and rolled stainless steel angel bar. The difference between the two is: 1, the stainless steel cold rolling forming angel bar to allow local buckling section, which can make full use of the angel bar buckling bearing capacity after; The hot rolled stainless steel local buckling angel bar are not allowed to cross section. 2, hot rolled stainless steel angel bar free torsional rigidity is higher than cold-rolled stainless steel angel bar, so hot rolled stainless steel angel bar of torsion performance is superior to cold rolled stainless steel angel bar.
