Cold rolled steel spcc coil specification (CR coil) is essentially hot-rolled steel that is cooled at room temperature and then annealed and temper rolled. This process will produce Cold rolled steel spcc coil specification with tighter dimensional tolerances and better surface finishes. Since the cold work hardening is caused by continuous cold deformation

The production process of Cold rolled steel spcc coil specification varies slightly according to the raw materials and the varieties and specifications of the products. Here is the making process of cold rolled steel.

Steel Grade	Chemical composition %
Steel Grade	C	Mn	P	S	Alta
SPCC	≤0.12	≤0.50	≤0.035	≤0.025	≥0.020

Raw Material- Pickling – Cold Rolling – Degreasing – Annealing – Rolling up – Packaging

Pickling. Hot-rolled coils pass through a pickling line to remove oxide scale on the surface by using hydrochloric acid solutions. Through the pickling process, there will be fewer surface flaws left.
Cold rolling. Pickled coils are rolled to a specified thickness in the cold-rolled mill.
Annealing. After removing the lubricant oil and contaminants by electrolytic cleaning, the coil will go through the continuous annealing process. It aims to make steel products with high tensile strength.
Rolling up into coils and then packaging for sale.

Purchasing sample of this type of steel is important for product development. By purchasing this material you can examine how this material can behave under the manipulative processes you will apply on it.
