The Geometry of Purity: Why Slab Form Matters
Pure iron slabs form the foundation of high-performance manufacturing. Our ISO 17025-certified slabs deliver:
| Property | Beilun Slabs | Industry Standard | Advantage |
|---|---|---|---|
| Thickness Tolerance | ±0.15mm (up to 300mm thick) | ±1.2mm | 8x Precision |
| Internal Porosity | ≤0.001% | 0.02-0.15% | 99% Reduction |
| Grain Orientation | Random ±3° (Isotropic) | ±15° | Uniform Machinability |
| Residual Stress | <15MPa (Laser-verified) | 50-120MPa | Warpage Immunity |
Proprietary Slab Production Technology
