Manufacturing Process:
- Pickling (removes scale from hot-rolled steel)
- Cold rolling through rollers at ambient temperatures
- Annealing (optional) to improve ductility
- Skin pass for final surface texture
Key Properties:
- High dimensional accuracy
- Smooth and clean surface
- Greater tensile strength than hot-rolled steel
- Available in coils or sheets
Applications:
- Automotive body panels
- Home appliances (refrigerators, washing machines)
- Furniture and filing cabinets
- Electrical panels
- Precision tubing
Advantages:
- Better surface finish
- Higher strength-to-weight ratio
- Ideal for painting or plating
- Consistent thickness
Limitations:
- More expensive than hot-rolled steel
- Less ductile without annealing
