Carbon Steel Rolled Coil B550L Is Used for Automotive

Cold-rolled steel is steel produced by cold rolling. Cold rolling is a steel plate obtained by further rolling the No. 1 steel plate to a target thickness at room temperature. Compared with hot-rolled steel sheets, cold-rolled steel sheets have more accurate thickness, smooth and beautiful surface, and also have various superior  mechanical properties, especially in terms of processing performance. Because cold-rolled raw coils are relatively brittle and hard, they are not suitable for processing, so usually cold-rolled steel sheets are required to be annealed, pickled and surface-leveled before being delivered to customers. The maximum thickness of cold rolling is below 0.1--8.0MM. For example, the thickness of cold-rolled steel sheets in most factories is below 4.5MM; the minimum thickness and width are determined according to the equipment capacity of each factory and market demand.
The difference between cold-rolled steel and hot-rolled steel is not in the smelting process, but in the rolling temperature, or the termination temperature of rolling. The finish rolling temperature lower than the recrystallization temperature of the steel becomes cold rolled steel. Hot-rolled steel is easy to roll and has high rolling efficiency, but the steel is oxidized under hot-rolled conditions, and the surface of the product is black and gray. Cold-rolled steel requires high mill power and low rolling efficiency, and intermediate annealing is required to eliminate work hardening during the rolling process, so the cost is also high, but cold-rolled steel has a bright surface and good quality, and can be directly used for processing Finished products, so cold-rolled steel sheets are widely used.
