Stainless Steel Cold-Rolled Coil – Overview

Definition:
A stainless steel cold-rolled coil (CRC) is a flat stainless steel sheet rolled at room temperature into a coil. Cold rolling improves the surface finish, dimensional accuracy, and mechanical properties compared to hot-rolled steel.

Key Features of Cold-Rolled Stainless Steel:

• Smooth, high-quality surface finish (2B, BA, No.4, or mirror finishes)
• Tighter thickness tolerances than hot-rolled coils
• Better flatness and edge quality
• Higher yield strength due to work hardening

Common Grades:

• 201: Cost-effective, indoor use, moderate corrosion resistance
• 304: Standard grade, excellent corrosion resistance, widely used
• 316: High corrosion resistance, suitable for marine and chemical environments
• 430: Decorative, magnetic, less corrosion-resistant

Thickness Range:

• Typically 0.3 mm – 3 mm, depending on application
• Width: Standard 1000 mm – 1500 mm, or custom

Surface Finishes:

• 2B: Smooth, dull finish, standard industrial use
• BA (Bright Annealed): Shiny, reflective finish
• No.4 / Brushed: Satin finish for decorative purposes
• Mirror / Polished: Highly reflective finish

Applications of Cold-Rolled Stainless Steel Coil

1. Construction & Architecture:
   • Wall panels, ceilings, staircases, elevator doors
   • Decorative and structural components
2. Appliances & Kitchenware:
   • Refrigerators, sinks, ovens, cookware, and countertops
3. Industrial & Mechanical:
   • Machine parts, flanges, enclosures, ducting, tubing
4. Automotive & Transportation:
   • Decorative trims, protective panels, vehicle parts
5. Fabrication & Manufacturing:
   • Can be cut, bent, embossed, or formed into sheets, discs, or other shapes
