CRC

CRC in the context of steel and manufacturing stands for Cold-Rolled Coil or Cold-Rolled Steel.

Process and Properties

CRC is produced by taking hot-rolled steel (HRC)—which is thicker and has a rough surface finish—and processing it further in a cold reduction mill. This process involves rolling the steel strip below its recrystallization temperature (at ambient temperature) to reduce its thickness.

This cold working fundamentally alters the material's properties

1. Dimensional Precision: CRC exhibits highly accurate dimensional tolerances, particularly in thickness, making it ideal for processes requiring tight fitments.
2. Surface Finish: It possesses a significantly smoother and cleaner surface finish than HRC, which is essential for applications requiring plating, painting, or decorative finishes.
3. Mechanical Strength: The cold working increases the material's hardness and tensile strength.

CRC is majorly used for applications like automotive parts, appliances, furniture, and any type of high-precision tubing where dimensional accuracy and surface quality are prioritized.
