How to control quality of SA573 Gr.58 cold rolled technique

Cold-rolled strips are widely used, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, food cans. Cold rolled steel sheet is the abbreviation of ordinary carbon structural steel cold rolled plate, SA573 Gr.58 cold rolled technique, also called cold rolled plate. The cold-rolled 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.

The cold rolled sheet does not produce scale because it is rolled at room temperature. Therefore, the surface quality of cold plate is good and the dimension precision is high. In addition, the mechanical and technological properties of cold rolled coil are better than that of hot-rolled steel sheet. In many fields, especially in the field of home appliance manufacturing, it has gradually replaced hot-rolled steel sheet, SA573 Gr.58 cold rolled technique.

SA573 Gr.58 cold rolled technique Weldability refers to the performance of the weld joint with the expected quality requirements obtained by common welding methods under specific structure and process conditions. Weldability is generally judged by the crack sensitivity and the change of mechanical properties of weld zone. The ability of steel materials to withstand bending without cracking at room temperature is called cold bending. The greater the bending capacity before crack, the better the cold bending performance of the steel material.
