According to the different needs of the production enterprises, the cold-rolled sheets are usually divided into: general cold-rolled sheets, stamping-grade cold-rolled sheets, deep-drawn, deep-deep and ultra-deep-stage cold-rolled sheets, which are generally delivered in coils and flat sheets. The thickness is expressed in millimeters, the width is generally 1000mm and 1250mm, and the length is generally 2000mm and 2500mm.
Commonly used grades are: Q195, Q215, Q235, 08AL, SPCC, SPCD, SPCE, SPCEN, ST12, ST13, ST14, ST15, ST16, DC01, DC03, DC04, DC05, DC06, etc.;
The difference between ST12 and SPCC: the mechanical properties of the two products are almost the same, but the return method is different. The tensile properties of ST12 material are relatively stronger than SPCC.
Japanese JIS standard material meaning SPCC---S is expressed as steel, P is represented as a plate, C is cold, C is commercial, and is a Japanese JIS standard.
For example, Anshan Steel produces ST12, 1*1250*2500/C, which is expressed as: ST12 ordinary cold plate, thickness 1mm, width 1250mm, length 2500mm or C coil. The appearance is tinplate fine packaging, the mechanical properties are the most common, the most basic steel number, can only be used for bending forming, can not be used for stamping. Used for mechanical biting, such as the outer casing of a refrigerator, a vehicle fuel tank, and the like.
