Cold rolled steel sheet

Cold rolled steel sheet is steel produced by cold rolling. Cold rolling is the further thinning of the hot rolled coil to the desired thickness of steel plate at room temperature. Compared with hot-rolled steel plate, cold-rolled steel plate thickness is more accurate, and the surface is smooth and beautiful, but also has a variety of superior mechanical properties, especially in terms of processing properties. Cold rolled steel requires large rolling power, low rolling efficiency, and intermediate annealing in order to eliminate work hardening during the rolling process, so the cost is also high, but the surface of cold rolled steel is bright, good quality, and can be directly used to process finished products, so cold rolled steel sheet is widely used. Widely used in construction, electrical appliances, transportation, agriculture, animal husbandry, automobile, hardware, furniture and other industries.
