Overview Hot rolling is rolling above the recrystallization temperature, contrary to cold rolling which is rolling below the recrystallization temperature. To put it simply, hot rolling is a process in which the steel billet is subjected to several rounds of rolling after heating, and then trimmed and corrected into steel sheet. It can significantly reduce energy consumption and reduce costs. That is, since the metal features high plasticity and low deformation resistance during hot rolling, it...
Overview The application of stainless steel materials in automobiles began with veneering materials for decoration but has recently extended to the exhaust systems.
