cold rolled steel information

Cold-rolled steel sheet is the abbreviation of ordinary carbon structural steel cold-rolled sheet, commonly known as cold plate. It is made of ordinary carbon structural steel hot-rolled steel strip, which is further cold-rolled into a steel sheet with a thickness of less than 4 mm. Since it is rolled at normal temperature and does not produce iron oxide skin, the surface quality of the cold plate is good, the dimensional accuracy is high, and the annealing process is superior to the hot-rolled steel sheet in mechanical properties and process performance, in many fields, especially In the field of home appliance manufacturing, it has gradually replaced hot-rolled steel sheets.

 

Since no heating is carried out during the production process, there are no defects such as pitting and iron oxide which are often caused by hot rolling, and the surface quality is good and the finish is high. Moreover, the dimensional accuracy of the cold rolled product is high, and the performance and organization of the product can meet some special use requirements, such as electromagnetic performance, deep drawing performance and the like.

 

Thickness: 0.15-2mm, width 600-2 000mm.

 

Grade: Q195A-Q235A, Q195AF-Q235AF, Q295A(B)-Q345 A(B); SPCC, SPCD, SPCE, ST12-15; DC01-06

 

Cold rolled strips are used in a wide variety of applications, such as automotive manufacturing, electrical products, rolling stock, aviation, precision instruments, and food cans.
