High-Tensile Stainless Steel Coil | Customized for Industrial Use
Product Overview
Our stainless steel coil solutions are engineered for demanding industrial environments, combining exceptional tensile strength, corrosion resistance, and versatility. Designed for applications in automotive, construction, aerospace, and machinery manufacturing, these coils are available in grades like 304, 316L, and SUS430. The stainless steel coil tubing variant is ideal for hydraulic systems and heat exchangers, while stainless steel coil nails provide unmatched durability for structural fastening.

Performance Characteristics
1. Tensile & Bend Strength
- Tensile Strength:
- 304L: 485–620 MPa | 316L: 520–690 MPa | SUS430: 450–600 MPa.
- These values exceed standard mild steel by 30–50%, making our coils suitable for high-stress components like automotive chassis and crane booms.
- Bend Strength:
- Cold-rolled stainless steel coil retains ductility even at subzero temperatures (-50°C), while hot-rolled variants withstand repeated thermal cycling without cracking.
2. Weight Calculation
Use the formula:
Weight (kg) = Width (mm) × Thickness (mm) × Length (m) × Density (7.93 g/cm³)
Example: For a 1000mm-wide, 2mm-thick, 50m-long coil:
1000 × 2 × 50 × 7.93 = 793 kg
3. Rust Prevention
While stainless steel coil inherently resists oxidation, prolonged exposure to chlorides (e.g., coastal environments) or mechanical abrasion can cause localized pitting. Our coils undergo passivation treatments to enhance chromium oxide layer formation, reducing corrosion risks by 60%.
4. Identification & Marking
- Laser-etched labels include: Grade (e.g., 304L), Batch Number, Thickness/Width, and Compliance Standard (ASTM/JIS).
- Color-coded edges: Green for 304L, Red for 316L, Blue for SUS430.
Manufacturing Process
| Stage | Description |
|---|---|
| Cold Rolling | Precision reduction of thickness (±0.02mm tolerance) for uniform grain structure. |
| Annealing | Heat treatment at 1010–1120°C to restore corrosion resistance and ductility. |
| Pickling | Acid bath removal of oxide layers for a clean, smooth surface. |
| Surface Finishing | Custom textures (e.g., HL for architectural use) via grinding or brushing. |
| Slitting | High-speed cutting to customer-specified widths (e.g., for stainless steel coil nails). |
