Cold rolled steel is the steel produced by cold rolling. Cold rolling is to further thin No.1 steel plate to the target thickness at room temperature. Compared with hot rolled steel plate, cold rolled steel plate is more accurate in thickness, smooth and beautiful in surface, and has various superior mechanical properties, especially in processing performance.
Because the cold rolled original coil is brittle and hard, it is not suitable for processing, so the cold rolled steel plate is usually required to be delivered to the customer after annealing, pickling and surface smoothing. The maximum thickness of cold rolled steel sheet is 0.1-8.0MM or less, for example, the thickness of cold rolled steel sheet in most factories is 4.5MM or less; The minimum thickness and width are determined according to the equipment capacity and market demand of each factory.
