Cold rolled sheet knowledge

Cold-rolled sheet refers to ordinary carbon structural steel cold-rolled sheet. The cold plate 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. Due to rolling at room temperature, no iron oxide scale is produced. Therefore, the cold plate has good surface quality and high dimensional accuracy. With the addition of annealing treatment, its mechanical properties and process properties are superior to hot-rolled thin steel plates. In many fields, especially In the field of home appliance manufacturing, it has gradually replaced hot-rolled steel sheets.

Application fields: Cold-rolled strips are widely used, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, food cans, etc.

Cold-rolled ordinary thin steel plate: cold-rolled from ordinary carbon structural steel or low-alloy structural steel. The surface quality of cold rolled sheet is better. Has good stamping properties. It is required to ensure that the cold bending and cup tests are qualified, and it is often used in industries such as automobiles and raw materials for coated plates.

Cold-rolled high-quality thin steel plate: mainly includes various high-quality steel cold-rolled thin plates, the most commonly used is carbon structural steel plate, especially cold-rolled thin steel plate for deep drawing, which is cold-rolled thin plate made of low-carbon high-quality steel 08AI, widely used Auto tractor industry.

Cold-rolled steel plate, smooth surface, excellent processing, used in home appliances such as automobiles, refrigerators, washing machines, industrial equipment, and various building materials. With the development of economy, cold-rolled steel plate has been called the necessary material of modern society. Classification of cold-rolled products: hot-rolled pickling, hard-rolled coil, ordinary cold-rolled, galvanized steel coil, electro-tinned, color-coated, electrical steel (silicon steel sheet), etc. .
