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

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