Cold Rolled Stainless Steel Coil
Product Overview
Cold Rolled Stainless Steel Coil is produced through multi-pass cold reduction of hot rolled stainless steel, followed by controlled annealing, pickling, and precision finishing.
It provides:
- Stable dimensional accuracy
- Consistent surface quality
- Reliable mechanical performance for industrial forming
It is widely used in:
home appliances, kitchen equipment, architectural systems, automotive components, and precision stamping applications.
Manufacturing System (Audit-Ready Production Structure)
Our production system integrates a fully controlled stainless steel processing line:
- 6-high precision cold rolling mills (AGC/AFC system)
- Continuous annealing & pickling line (CAPL)
- Precision slitting lines (10 mm minimum width capability)
- Online thickness, width, and surface inspection systems
Annual production capacity: 180,000+ metric tons (auditable internal capacity range)
Export regions: Southeast Asia, Middle East, South America, Europe
Full Traceability System
Each coil is assigned a unique Heat Number, enabling traceability from raw material melting to final shipment.
Production and inspection records can be provided for:
Customer audit
Quality verification
Long-term supply agreements
Key Advantages
Controlled cold rolling ensures consistent thickness and flatness.
Thickness tolerance: ±0.01 – 0.05 mm (depending on specification)
Stable flatness suitable for stamping and forming lines
Engineering principle:
Controlled deformation below recrystallization temperature improves dimensional precision through dislocation strengthening and rolling tension regulation.
Surface is processed through annealing, pickling, and finishing.
- Clean, oxide-free surface condition
- Controlled surface roughness for industrial and decorative use
Available finishes:
- 2B (standard industrial finish)
- BA (bright annealed finish)
- No.4 / HL (decorative finish)
Typical properties (Grade 304 reference):
Tensile Strength: 520–720 MPa
Yield Strength: ≥ 205 MPa
Elongation: ≥ 40%
Material behavior explanation:
Cold working increases strength through work hardening, while annealing restores ductility by refining grain structure.
- Suitable for stamping, bending, deep drawing, and stretching
- Uniform microstructure improves forming stability
- Compatible with automated production systems
