Factory-Delivery-DC04-DC05-ST12-ST13-ST14-Cold-Rolled-Steel-Coil-for-Automotive-Parts

Cold-rolled coils are metal coils that are further rolled at room temperature from hot-rolled coils. Compared with hot-rolled coils, cold-rolled coils have higher surface quality and dimensional accuracy.
Common cold-rolled coil materials include: low-carbon steel, stainless steel, aluminum alloy, copper alloy

Production Process:

7 Jan 2019

Hot rolling: Heat the steel billet and roll it into hot-rolled coils.
Pickling: Remove the oxide scale on the surface of the hot-rolled coils.
Cold rolling: Further roll at room temperature to achieve the required thickness and surface quality.
Annealing: Improve the mechanical properties of the material.
Finishing: Perform treatments such as flattening and cutting.
