High-Performance Stainless Steel Strip | Cold-Rolled & Custom Solutions
Product Overview
Our stainless steel strip products are engineered for industries demanding precision, durability, and corrosion resistance. Available in grades 304, 316L, and SUS430, these strips are cold-rolled to achieve ultra-thin profiles (0.05–3.0mm) with exceptional surface finishes. Ideal for automotive, aerospace, and architectural applications, our stainless steel metal strips and stainless steel trim strips combine versatility with industrial-grade performance.
Technical Specifications

Performance Characteristics
1. Tensile & Bend Strength
- Tensile Strength:
- 304L: 485–620 MPa | 316L: 520–690 MPa | SUS430: 450–600 MPa.
- These values ensure reliability in high-stress environments like aerospace structural panels and automotive exhaust systems.
- Bend Strength:
- Cold-rolled stainless steel strips maintain ductility even at subzero temperatures (-50°C), making them suitable for Arctic pipeline components.
2. Weight Calculation
Use the formula:
Weight (kg) = Width (mm) × Thickness (mm) × Length (m) × Density (7.93 g/cm³)
Example: For a 500mm-wide, 1.5mm-thick, 100m-long strip:
500 × 1.5 × 100 × 7.93 = 5,947.5 kg
3. Rust Prevention
While stainless steel strips inherently resist oxidation due to their chromium content (10.5–30%), prolonged exposure to chlorides (e.g., coastal saltwater) or acidic environments can cause pitting. Our strips undergo passivation treatments to enhance chromium oxide layer formation, reducing corrosion risks by 60%.
4. Identification & Marking
- Laser-etched labels include: Grade (e.g., 316L), Batch Number, Thickness/Width, and Compliance Standard (ASTM/EN).
- Color-coded edges: Blue for 304L, Yellow for 316L, Red for SUS430.
Manufacturing Process
| Stage | Description |
|---|---|
| Cold Rolling | Precision thickness reduction (tolerance ±0.01mm) for uniform grain structure. |
| Annealing | Heat treatment at 1010–1120°C to restore ductility and corrosion resistance. |
| Pickling | Hydrochloric acid bath to remove oxide layers and impurities. |
| Surface Finishing | Custom textures (e.g., brushed for stainless steel trim strips) via grinding or polishing. |
| Slitting | High-speed cutting to produce narrow stainless steel metal strips for electronics and medical devices. |
