Cold Rolled Coils

Cold rolled steel

Cold worked steels are typically harder and stronger than standard hot rolled steels.

CR coil sheet is essentially hot rolled steel that has been through further processing. Once hot rolled steel has cooled, it is then re-rolled at room temperature to achieve more exact dimensions and better surface qualities.

Cold "rolled" steel is often used to describe a range of finishing processes, though technically "cold rolled" applies only to sheets that undergo compression between rollers. Steel forms that are pulled, such as bars or tubes, are "drawn," not rolled. Other cold finishing processes include turning, grinding, and polishing-each of which is used to modify existing hot rolled stock into more refined products.

Cold rolled steel can often be identified by the following characteristics:

Better, more finished surfaces with closer tolerances

Smooth surfaces that are often oily to the touch

Bars are true and square, and often have well-defined edges and corners

Tubes have better concentric uniformity and straightness

1. High strength: 20% stronger than hot-rolled steel

2. High surface quality – smooth and easy to paint

3. Close tolerances

4. Good formability

5. Poor toughness and weldability

Mainly using low carbon steel, it requires good cold bending and welding properties, as well as certain stamping properties.

Cold-rolled steel coils are used in a wide range of applications, such as automobile manufacturing, electrical products, steel, aviation, precision instruments, canned foods, etc.
