Shanxi Jurun Technology Co., Ltd., based in Taiyuan, China, specializes in manufacturing premium SPHC grade pure iron hot-rolled coils with 2B surface finish. Our products deliver exceptional flatness and uniform surface quality essential for precision industrial applications. With strict control over chemical composition and rolling parameters, we ensure consistent mechanical properties across every coil. The optimized production process allows for cost-effective solutions without compromising material integrity.
This hot-rolled coil features a unique combination of pure iron composition and specialized 2B finish, providing superior corrosion resistance compared to standard hot-rolled products. The carefully controlled annealing process enhances formability while maintaining structural strength. Available in customized dimensions, our coils undergo rigorous non-destructive testing to guarantee defect-free surfaces suitable for high-visibility applications.
| Parameter | Specification | Testing Method |
|---|---|---|
| Yield Strength | 170-320 MPa | ASTM E8/E8M |
| Surface Roughness | Ra ≤ 0.8 μm | ISO 4287 |
| Carbon Content | ≤ 0.12% | Spark OES |
Key technical advantages include:
- Enhanced Formability: Uniform grain structure allows for deep drawing operations without surface cracking
- Consistent Thickness Tolerance: Maintains ±0.05mm precision across full coil length
- Oxidation Resistance: 2B finish provides passive protection layer reducing rust formation
- Weldability: Low carbon equivalent enables seamless welding operations
Ideal for manufacturing processes requiring both structural integrity and aesthetic surface quality, this material significantly reduces secondary processing costs. The optimized metallurgical properties ensure consistent performance in temperature variations from -20°C to 150°C. Our production facility utilizes continuous annealing lines with closed-loop temperature control to achieve homogeneous material characteristics.
FAQ Section
Q: What distinguishes 2B finish from other surface treatments?
A: 2B finish undergoes light cold-rolling after annealing, producing smoother, more reflective surfaces than standard hot-rolled products while maintaining better corrosion resistance than BA finishes.
Q: Can you provide material test certificates?
A: Mill test certificates including chemical composition and mechanical properties are available with each shipment.
Q: What packaging options are available?
A: Standard packaging includes waterproof paper wrapping and steel strap reinforcement. Custom packaging solutions can be arranged.
Q: How does SPHC grade differ from commercial grade steel?
A: SPHC (Steel Plate Hot Commercial) follows JIS G 3131 standards with tighter controls on carbon content and impurity levels for improved formability.
Q: What's the minimum order quantity?
A: MOQ starts at 20 tons, with smaller trial orders negotiable.
Q: How is dimensional accuracy maintained?
A: Our four-high rolling mills with automatic gauge control systems ensure thickness consistency within ±0.03mm of target specifications.
