Cold rolled steel sheet are mainly used in automobile, printed metal pail, building, building materials, and bicycle, etc. Additionally, it is the best material to manufacture organic coated strip.
Standard:JIS, ASTM, EN10130
Grade: SPCC, SPCD, ST12, ST13, ST14/16, DC01, DC02, DC03, DC04, DC05, DC06, Q195, Q195L,SAE1008,SAE1006
Szie: Thickness: 0.2-2.0mm
(1) when the strip steel is rolled in a cold state, because of the work hardening of the strip steel, it must be softened again by intermediate annealing, and its plasticity should be restored in order to continue rolling;
(2) Before rolling, the surface scale of strip steel must be removed, thus ensuring the surface smoothness of strip steel and reducing the wear of rolls;
(3) Tension rolling is adopted, which ensures the good shape of strip steel, controls the thickness deviation of strip steel, reduces the rolling pressure, and is beneficial to rolling thin gauge products.
(4) Process cooling and lubrication are adopted, which is convenient to control the temperature of the roll and strip steel, reduce the friction between the roll and strip steel and reduce the rolling pressure, which is beneficial to the shape control and prevents the strip steel from sticking to the roll.
Cold rolled steel strip is widely used in cutting-edge technical fields, such as automobile, instrumentation, radio, national defense and aerospace industry, etc.
Cold rolled steel according DIN EN 10130, 10209 and DIN 1623
Cold rolled steel is also part of our product portfolio. Cold rolled steel is excellent for cold forming. This product group assigned the grades DC01 to DC07, DC01EK to DC06EK, DC03ED to DC06ED and S215G to S325G.
The grades are classified according to the maximum permissible yield strength and can be subdivided as follows.
DC01 – This grade can be used for simple forming work, for example Bending, embossing, beading and pulling are used.
DC03 – This grade is suitable for forming requirements such as Deep drawing and difficult profiles suitable.
DC04 – This quality is suitable for high deformation requirements.
DC05 – This thermoforming grade is suitable for higher forming requirements.
DC06 – This special deep drawing quality is suitable for the highest deformation requirements.
DC07 – This super deep drawing quality is suitable for extreme deformation requirements.
The steel grades DC01EK, DC04EK and DC06EK are suitable for conventional single-layer or double-layer enamelling.
The steel grades DC06ED, DE04ED and DC06ED are suitable for direct enamelling as well as for enamelling according to the two-layer / one-firing method and for special applications of two-layer enamelling for low-distortion enamelling.
Mistakes such as pores, small grooves, small warts, slight scratches and a slight discoloration that does not affect the ability to reshape and adhere to surface coatings are permitted.
The better side must be free from defects so that the homogeneous appearance of a quality finish or an electrolytically applied coating is not impaired. The other side must at least meet the requirements of surface type A.
The surface finish may be particularly smooth, dull or rough. If no details are given when ordering, the surface finish will be delivered in a matt finish. The four surface finishes listed correspond to the center roughness values in the following table and must be tested in accordance with EN 10049.
