Cold Rolled Steel Sheets

Product Description

Cold Rolled Steel (CRS) Sheets are flat-rolled steel products produced through a cold rolling process, offering enhanced surface finish, dimensional accuracy, and mechanical properties. These sheets are widely used in applications requiring precision, strength, and a smooth surface finish.

Manufacturing Process

1. Hot Rolled Steel Preparation:
   • Sheets are first produced as hot rolled steel and then cooled.
2. Cold Rolling:
   • The cooled sheets are passed through rollers at room temperature to reduce thickness and enhance surface finish.
3. Annealing:
   • For better ductility and stress relief, sheets may undergo annealing.
4. Surface Finishing:
   • Sheets are polished or coated for specific applications.

Key Features

1. Dimensional Accuracy:
   • Uniform thickness and flatness.
2. Superior Surface Finish:
   • Smooth and shiny surface, ideal for applications requiring aesthetic appeal.
3. Enhanced Mechanical Properties:
   • Improved tensile strength and hardness.
4. Corrosion Resistance:
   • Often provided with coatings for better rust prevention.
5. Weldability and Formability:
   • Excellent for intricate designs and applications requiring shaping or joining.

Common Grades

• SPCC: For general use.
• SPCD: For deep drawing applications.
• SPCE: For extra-deep drawing purposes.
• IS 513 D: Indian standard for cold-rolled steel sheets.
• ASTM A1008: Standard specification for cold-rolled carbon steel.

Thickness Range

• Typically ranges from 0.3 mm to 3.2 mm, depending on the application and specifications.
