It is a product obtained by processing hot-rolled metal sheets under cold pressure. Because it has undergone multiple passes of cold rolling, its process performance is better than that of hot-rolled metal sheets. After quenching and tempering, it can obtain excellent physical properties.
1. Classification of main uses of general cold-rolled plates
According to the different requirements of manufacturing enterprises, cold rolled plates are generally divided into:
Generally, cold rolled plates, stamping die grade cold rolled plates, deep drawing, extra deep drawing and over digging upgraded cold rolled plates are used.
Generally supplied as waterproof membrane and tablet, the thickness is indicated in mm.
The total width is generally: 100mm and 1250mm, and the length is generally 2000mm and 2500mm.
Indicates that it is a general steel model, which is basically the same material as Q195, SPCC, and DC01 models;
ST13/14：
Indicates that it is a stamping die grade steel model, which is basically consistent with the 08AL, SPCD, and DC03/04 model materials;
ST15/16：
Indicates that it is a stamping die grade steel model, which is basically consistent with the 08AL, SPCE, SPCEN, and DC05/06 model materials.
3. How to indicate the model specifications of general cold-rolled plates
For example, ST12 produced by Shougang, 1*1250*2500/C, is expressed as: Model ST12 is a general cold-rolled steel plate, the thickness is 1250 mm, the width is 1250 mm, and the length is 2500 mm or C waterproof membrane.
The appearance is galvanized iron and the physical properties are average. The basic steel model can only be used for sheet metal bending and cannot be used for stamping dies. It is used in the mouth of mechanical equipment, such as refrigerator casings, car fuel tanks, etc.
