Understanding Steel Strip Specifications: Key Factors for Selection
Selecting the right steel strip hinges on precise specifications tailored to your application. AtGuangzhou Jiaxiao Material Technology Co., Ltée. (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. Thickness & Width: Precision for Diverse Needs
Steel strips are engineered for applications demanding ultra-thin profiles or robust thickness. Our production capabilities include:
- Thickness Range: 0.10mm to 5.00mm (tolerance: ±0.015mm to ±0.070mm).
- Width Range: 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, saw blades, 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 | Applications |
|---|---|---|---|
| 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, saw blades. |
| 60Si2Mn | GOST 60C2, AISI 9260 | Si: 1.50–2.00% | Heavy-duty coil springs, agricultural tools. |
3. Standard Tolerances vs. Custom Solutions
Standard Tolerances:
- Thickness: ±0.015mm (for <0.25mm) to ±0.070mm (3.20–5.00mm).
- Width: ±0.30mm (for <50mm width) to ±0.80mm (200–500mm width).
- Flatness: ≤0.1% cross camber (P4 class).
- Straightness: ≤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: Slit, rounded, or square edges to prevent injury and ease assembly.
- Length Cutting: Cut-to-length sheets (1m–5m) for reduced waste and streamlined production.
