Understanding Steel Strip Specifications: Key Factors for Selection
Selecting the right steel strip hinges on precise specifications tailored to your application. TạiCông ty TNHH Công nghệ Vật liệu Quảng Châu Jiaxiao, Ltd. (Jiaxiao MTC), we offer a wide range of cold rolled, annealed, and hardened-tempered steel strips with customizable dimensions, chemistries, and tolerances. Below, we break down critical parameters and how they impact performance.
1. Độ dày & Chiều rộng: Precision for Diverse Needs
Steel strips are engineered for applications demanding ultra-thin profiles or robust thickness. Our production capabilities include:
- Phạm vi độ dày: 0.10mm đến 5,00mm (tolerance: ±0.015mm to ±0.070mm).
- Phạm vi chiều rộng: 2mm to 1250mm (tolerance: ±0.20mm to ±0.80mm).
Applications by Thickness:
- 0.1–0.5mm: Precision springs, shims, and electronic components.
- 1.0–3.0mm: Automotive clutch discs, cưa lưỡi, and construction tools.
- 3.0–5.0mm: Heavy-duty industrial springs and machinery parts.
2. Chemical Composition: Tailoring Strength and Durability
Material grade directly impacts hardness, corrosion resistance, and formability. Key steel grades we supply include:
| Grade | Equivalent Standards | Key Elements | Ứng dụng |
|---|---|---|---|
| C75s | AISI 1074, DIN CK75 | C: 0.72–0.80% | Shutter springs, high-stress flat springs. |
| 50CRV4 | EN 50CrV4, AISI 6150 | Cr: 0.80–1.10% | Automotive valve springs, cưa lưỡi. |
| 60Si2mn | GOST 60C2, AISI 9260 | Si: 1.50–2.00% | Heavy-duty coil springs, agricultural tools. |
3. Standard Tolerances vs. Custom Solutions
Standard Tolerances:
- Độ dày: ±0.015mm (for <0.25mm) to ±0.070mm (3.20–5.00mm).
- Chiều rộng: ±0.30mm (for <50mm width) to ±0.80mm (200–500mm width).
- Flatness: ≤0.1% cross camber (P4 class).
- Độ thẳng: ≤0.3mm deviation over 3m (R4 class).
Custom Solutions:
- Special Tolerances: Achieve P5 (ultra-tight flatness) or R9 (bespoke straightness) for niche applications.
- Edge Finishes: Khe hở, làm tròn, or square edges to prevent injury and ease assembly.
- Length Cutting: Cut-to-length sheets (1m–5m) for reduced waste and streamlined production.
