Galvanized Steel Sheet Coil HX180BD
Hot dipped galvanized steel coil HX180BD is a grade under the European EN 10346 standard, designed for automotive parts, high-end home appliances, electrical cabinets and other scenes with strict requirements on material strength, formability and corrosion resistance.
As a high-strength steel with deep zinc-iron alloy coating (GA), it perfectly balances the 180MPa grade yield strength and excellent deep drawing performance, and is 40% stronger than the traditional DX51D material, while reducing the overall manufacturing cost by 15%.
HX180BD hot dipped galvanized steel coil and sheet, as a representative of the new generation of high-performance composite materials, is gradually showing its potential in industrial applications. This material not only inherits the high strength and durability of traditional materials, but also achieves a qualitative leap in light weight and environmental protection.
| Parameter category | HX180BD | Compared with conventional grades (DX54D) | Industry advantages |
|---|---|---|---|
| Substrate strength | Yield strength ≥180MPa (HX grade high strength) | 120-160MPa | Deformation resistance +25% |
| Coating type | Zinc-iron alloy (GA) / pure zinc (GI) | Pure zinc (Z) | Improved weldability by 30% |
| Coating weight | Z60-Z180 (double-sided g/m²) | Z60-Z120 | Corrosion resistance life 2X |
Applications
| Industry | Typical Components | Customer Pain Points | HX180BD Solution |
|---|---|---|---|
| New energy vehicles | Battery tray/motor end cover | Welding porosity, salt spray corrosion | GA coating + zero-defect weld |
| White appliances | Refrigerator door panel/washing machine inner drum | Bending cracks, surface scratches | 34% elongation + fingerprint-resistant coating |
| Building curtain wall | Hidden fasteners/decorative lines | Stress corrosion cracking (SCC) | 180MPa high strength + anti-hydrogen embrittlement treatment |
