Introduction To Ordinary Cold Rolled Sheet Grade

Classification of the Use of Ordinary Cold Rolled Sheets

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.

The Grade of Ordinary Cold Rolled Sheet

Commonly used grades are: Q195, Q215, Q235, 08AL, SPCC, SPCD, SPCE, SPCEN, ST12, ST13, ST14, ST15, ST16, DC01, DC03, DC04, DC05, DC06, etc.;

• ST12: It is expressed as the most common steel number, which is basically the same as Q195, SPCC, DC01 grade materials;
• ST13/14: It is expressed as the steel grade of the stamping grade, which is basically the same as the 08AL, SPCD, DC03/04 grade material;
• ST15/16: Indicates the steel grade of the stamping grade, which is basically the same as the 08AL, SPCE, SPCEN, and DC05/06 grades.

Method for indicating the size of ordinary cold rolled sheet

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.
