COLD ROLLED STEEL
Cold rolled steel is essentially hot rolled steel that has been further processed by being allowed to cool at room temperature and annealed or temper rolled. Cold rolling produces steel with closer dimensional tolerances and a wider range of surface finishes than hot rolling. It is also up to 20% stronger than hot rolled through the use of strength hardening.
When making more precise shapes, the process involves:
- Breakdown
- Semi-Finishing
- Sizing
- Semi-Roughing
- Roughing
- Finishing
ADVANTAGES OF COLD ROLLED STEEL
Cold rolled steel typically results in a product with a better, more finished surface with closer tolerances. It also yields smoother surfaces that are oily to the touch. Other advantages include:
- Can be used in precise applications
- Harder and stronger than hot rolled steels
- Increased hardness, resistance against tension breaking, and resistance against deformation due to work hardening
- Aesthetically pleasing finish with a wider range of surface finishes
APPLICATIONS OF COLD ROLLED STEEL
Cold rolled steel is used in applications where tolerances, surface conditions, concentricity, and straightness are factors. It also offers a more aesthetic and visually appealing surface. Other applications include:
- Home Appliances
- Metal Furniture
- Aerospace Structural Components
- Automotive Parts
