Cold rolled carbon steel plate is a low carbon steel sheet processed by cold rolling. Its thickness is usually less than 4mm, with high surface finish and excellent dimensional accuracy. Its mechanical properties and process performance are significantly improved compared with hot rolled steel plate. During the cold rolling process, annealing treatment is used to eliminate internal stress and enhance the ductility of the material, making it particularly suitable for forming processes such as deep drawing and bending. At the same time, the corrosion resistance can be further improved through surface treatment such as galvanizing and coating. It is an indispensable basic material in modern industry.
