As a leading steel manufacturer based in the heart of China's steel industry hub, Shanxi Jurun Technology leverages Taiyuan's rich metallurgical resources to deliver premium pure iron hot-rolled coils engineered specifically for automotive applications. Our coils provide unmatched material consistency crucial for high-precision stamping processes in body panel manufacturing. With over a decade of specialized production experience, we've perfected the balance between formability and structural integrity required for modern vehicle safety standards.
The Jurun Steel pure iron HR coils feature:
- Superior purity levels (≤0.008% carbon content) ensuring exceptional ductility
- Precisely controlled grain structure for consistent mechanical properties
- Optimal surface roughness (Ra 0.8-1.5μm) for enhanced coating adhesion
- Minimal thickness tolerance (±0.05mm) across entire coil length
- Customizable annealing options for specific hardness requirements
| Parameter | Standard Value | Testing Method |
|---|---|---|
| Yield Strength | 140-180 MPa | ASTM E8 |
| Tensile Strength | 270-310 MPa | ASTM E8 |
| Elongation | 38-42% | ASTM E8 |
| Hardness (HRB) | 45-55 | ASTM E18 |
Manufacturers benefit from our proprietary edge conditioning system that eliminates micro-cracking during blanking operations, reducing scrap rates by up to 15% compared to conventional HRC products. The material's homogeneous microstructure allows for:
- 25% deeper drawing capability for complex geometries
- Consistent springback predictability (±0.3° variance)
- Reduced die wear through uniform hardness distribution
- Enhanced spot welding performance with stable electrical resistance
Located just 120km from major iron ore sources, Shanxi Jurun maintains stringent quality control through vertically integrated production. Each batch undergoes seven-stage inspection including ultrasonic testing, laser dimensional scanning, and spectrochemical analysis. Our 150,000-ton annual production capacity ensures reliable JIT delivery to global Tier 1 automotive suppliers.
