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
- Dimensional Precision: CRC exhibits highly accurate dimensional tolerances, particularly in thickness, making it ideal for processes requiring tight fitments.
- Surface Finish: It possesses a significantly smoother and cleaner surface finish than HRC, which is essential for applications requiring plating, painting, or decorative finishes.
- 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.
