Cold-rolled steel Coil is low-carbon hot-rolled steel that has been rolled at room temperature, below its recrystallization temperature. The steel is then cleaned of oxide scale and finished in a specific series of rolling to just over the desired thickness, heating to controlled temperatures, and final rolling to the desired thickness. This produces steel with a close thickness tolerance (+/-.0015” or better) and a wide range of controlled surface finishes. The process of cold rolling increasing the steel’s strength and hardness, while decreasing its ductility. Not only can you achieve improved mechanical properties, cold rolling provides more control over the shape and final dimensions of the product.

Use cold-rolled steel where thickness tolerances and surface conditions have a narrow window for success in your application. As a cold rolled steel coil supplier, we will be glad to help you select the exact grade for your specific needs.

Commonly Used Steel Codes:

DC01 (tensile strength 270 – 410 MPa)– This grade can be used for simple forming work such as using bending, embossing, crimping, and stretching.

DC02/DC03 – These grades are suitable for forming requirements such as deep drawing and difficult profiles.

DC04 – This quality can meet high deformation requirements.

DC05/06/07 – These deep drawing quality grades are suitable for higher forming and deformation requirements. Below are their mechanical properties.
