Introduction

Cold rolled sheet is the abbreviation of ordinary carbon structural steel cold-rolled sheet, also called cold-rolled sheet, cold-rolled sheet is a hot-rolled strip of ordinary carbon structural steel, which is further cold-rolled into a steel plate with a thickness of less than 4mm. Because rolling at room temperature does not produce scale, the cold plate has good surface quality and high dimensional accuracy. Coupled with annealing treatment, its mechanical properties and process properties are better than hot-rolled thin steel plates. In many fields, especially In the field of home appliance manufacturing, it has gradually replaced hot-rolled steel sheets.
