DX53D Z100
DX53D Z100 is a high-formability galvanized steel combining:
- Low-carbon deep drawing steel (DX53D)
- Zinc coating protection (Z100 ~100 g/m²)
其主要优点包括:
- Excellent ductility and stamping performance
- Reliable corrosion resistance
- Stable mechanical strength
- Suitable for complex forming applications
Because of this balance, DX53D Z100 is one of the most widely used galvanized steels for precision forming and industrial manufacturing.
- 描述
描述
DX53D Z100 is a hot-dip galvanized deep-drawing steel that combines a low-carbon steel substrate with a zinc coating of approximately 100 克/平方米 (Z100 coating class). It is widely used in automotive panels, construction components, and household appliance parts due to its excellent formability and corrosion resistance.
DX53D镀锌钢 is designed for complex forming operations, where high elongation and stable mechanical properties are required.
1. What Does “DX53D Z100” Mean?
- DX53D → Deep drawing quality cold-rolled steel (very good formability grade)
- Z100 → Zinc coating mass ≈ 100 克/平方米 (both sides total coating weight system depending on standard)
- Base standard → EN 10346 hot-dip galvanized steel system
所以, DX53D Z100 = deep drawing steel + medium zinc protection coating
2. Chemical Composition of DX53D Steel Base Material
The steel substrate is a low-carbon steel optimized for forming performance:
| 元素 | 内容 (%) | 功能 |
|---|---|---|
| 碳 (C) | ≤ 0.10–0.12 | Improves strength, keeps good ductility |
| 硅 (和) | ≤ 0.50 | Controls oxidation behavior |
| 锰 (锰) | ≤ 0.60 | 提高韧性 |
| 磷 (磷) | ≤ 0.10 | Limited impurity control |
| 硫 (S) | ≤ 0.045 | 改善机械加工性控制 |
| 铝 (铝) | ≥ 0.015 | Deoxidation and grain control |
| 氮 (氮) | ≤ 0.012 | 稳定结构 |
👉 这种成分确保 high elongation and excellent deep drawing ability.
3. 镀锌层组合物 (Z100 Layer)
这 Z100 coating refers to a hot-dip zinc layer:
| 成分 | 描述 |
|---|---|
| 锌 (Zn) | 主保护层 |
| Iron-Zinc intermetallic layer | Bonding layer between steel and coating |
| 镀层质量 | ~100 g/m² total |
The coating forms a metallurgical bond, 不仅仅是表面层, which improves durability.
4. Mechanical Properties of DX53D Z100
DX53D steel provides excellent forming performance:
| 财产 | 价值 |
|---|---|
| 抗拉强度 | 270 – 380 MPA |
| 屈服强度 | 140 – 260 MPA |
| 伸长 | ≥ 28 – 40% |
| 硬度 | 〜80 – 120 HB |
| 弹性模量 | 〜210 GPa |
👉 主要特点: 非常高的伸长率 + low yield strength → excellent forming capability
