SPCC Cold rolled steel coil DC01 DC02 CRC

SPCC Cold rolled steel coil DC01 DC02 CRC

Cold rolled steel coil is made from hot-rolled steel coil as raw material, which is subjected to acid washing to remove oxide skin and then subjected to cold continuous rolling. The finished product is rolled hard coil. Due to the cold work hardening caused by continuous cold deformation, the strength and hardness of the rolled hard coil increase, and the toughness and plasticity index decrease. Deep processing requires annealing treatment.

Product Description

Due to the lack of heating during the production process of cold rolled steel coils, there are no defects such as pits and oxide scales that often occur during hot rolling. The surface quality is good and the smoothness is high. Moreover, the dimensional accuracy of cold rolled steel coils is high, and the performance and structure of the products can meet some special usage requirements, such as electromagnetic performance, deep drawing performance, etc.
