Grades Of Cold-rolled Steel Plates


Brief introduction of COLD-ROLLED steel plate

It is produced from hot rolled sheet through cold pressure processing. The surface quality is better than that of hot rolled sheet, after heat treatment, Cold-rolled Steel Plates good mechanical properties can be obtained.

1, the use of cold-rolled steel plate classification

According to the different needs of the production enterprises, cold-rolled plate is usually divided into:

Cold rolled sheet, punching grade cold rolling plate, deep drawing, Cold-rolled Steel Plates deep drawing and ultra deep drawing cold rolling plate are generally used,

Generally delivered in rolls and plates, in millimeters,

The width is generally: 1000mm and 1250mm, the length is generally 2000mm and 2500mm.

2, cold-rolled steel plate grades

Commonly used brands:

Q195, Q215, Q235, 08AL, SPCC, SPCD, Spce, Spcen, ST12, ST13, ST14, ST15, ST16, DC01, DC03, DC04, DC05, DC06, etc.;


Expressed as the most common steel number, and Q195, SPCC, Cold-rolled Steel Plates DC01 brand materials are basically the same;


The steel number of the stamping grade is basically the same as that of 08AL, SPCD and dc03/04.


For the stamping grade of the steel, and 08AL, Spce, Spcen, dc05/06 grade material is basically the same.

3. Designation of plate size for cold-rolled steel plates

For example, Angang production ST12, 1*1250*2500/C, expressed as: Brand ST12 ordinary cold plate, thickness of 1mm, width of 1250mm, the length of 2500mm or C coil.

The appearance of tin fine packaging, mechanical properties of the most common, the most basic steel, can only be used for bending molding, can not be used for stamping. Cold-rolled Steel Plates Used in mechanical bites

such as the shell of the refrigerator, vehicle fuel tank.

ST13 above products, used in the need for deep industry, such as automobile manufacturing, diesel engine fuel tank, and so on, specifically, which one to see the requirements of the deep drawing.

The difference between ST12 and SPCC is that the mechanical properties of the two products are similar, but the product of the ST12 material is more tensile than SPCC.
