Understanding Steel Strip Specifications: Key Factors for Selection
Selecting the right steel strip hinges on precise specifications tailored to your application. ВGuangzhou Jiaxiao Material Technology Co., ООО. (Цзясяо МТС), we offer a wide range of cold rolled, отожженный, and hardened-tempered steel strips with customizable dimensions, chemistries, and tolerances. Below, we break down critical parameters and how they impact performance.
1. Толщина & Ширина: Precision for Diverse Needs
Steel strips are engineered for applications demanding ultra-thin profiles or robust thickness. Our production capabilities include:
- Диапазон толщины: 0.10mm to 5.00mm (толерантность: ±0.015mm to ±0.070mm).
- Диапазон ширины: 2mm to 1250mm (толерантность: ±0.20mm to ±0.80mm).
Applications by Thickness:
- 0.1–0.5mm: Precision springs, прокладки, and electronic components.
- 1.0–3.0mm: Automotive clutch discs, лезвия пилы, and construction tools.
- 3.0–5.0mm: Heavy-duty industrial springs and machinery parts.
2. Химический состав: Tailoring Strength and Durability
Material grade directly impacts hardness, устойчивость к коррозии, and formability. Key steel grades we supply include:
| Оценка | Equivalent Standards | Key Elements | Приложения |
|---|---|---|---|
| C75S | АИСИ 1074, DIN CK75 | С: 0.72–0.80% | Shutter springs, high-stress flat springs. |
| 50КрВ4 | EN 50CrV4, АИСИ 6150 | Кр: 0.80–1.10% | Automotive valve springs, лезвия пилы. |
| 60Si2Mn | GOST 60C2, АИСИ 9260 | И: 1.50–2.00% | Heavy-duty coil springs, agricultural tools. |
3. Standard Tolerances vs. Custom Solutions
Standard Tolerances:
- Толщина: ±0.015mm (for <0.25мм) to ±0.070mm (3.20–5.00mm).
- Ширина: ±0.30mm (for <50mm width) to ±0.80mm (200–500mm width).
- Flatness: ≤0.1% cross camber (P4 class).
- Прямолинейность: ≤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: щель, округлый, or square edges to prevent injury and ease assembly.
- Length Cutting: Cut-to-length sheets (1m–5m) for reduced waste and streamlined production.
