描述
DX54D steel specification refers to a high-formability cold-rolled steel grade designed for deep drawing and complex stamping applications. It is commonly used in automotive panels, appliance housings, construction components, and other precision-formed metal parts.
DX54D钢 belongs to the DX series in EN 10346 标准, which are optimized for excellent ductility and stable forming performance.
1. What Is DX54D Steel?
DX54D钢 is a low-carbon steel specifically developed for:
- Deep drawing operations
- Complex stamping processes
- High deformation forming
- Stable surface quality after processing
The “54” in DX54D indicates a higher forming quality level compared to lower DX grades such as DX51D or DX52D.
2. 化学成分 (基础钢)
The steel substrate is designed to ensure high ductility and stable performance:
| 元素 | 内容 (%) | 功能 |
|---|---|---|
| 碳 (C) | ≤ 0.12 | 保持延展性 |
| 锰 (锰) | ≤ 0.60 | 提高韧性 |
| 硅 (和) | ≤ 0.50 | 控制钢结构 |
| 磷 (磷) | ≤ 0.10 | 限制杂质 |
| 硫 (S) | ≤ 0.045 | 改善机械加工性控制 |
| 铝 (铝) | ≥ 0.015 | 脱氧和晶粒细化 |
| 氮 (氮) | ≤ 0.012 | 稳定微观结构 |
👉 Low carbon content is the key factor enabling excellent formability.
3. 机械性能
DX54D钢 provides superior forming performance:
| 财产 | 价值 |
|---|---|
| 屈服强度 | 120 – 220 MPA |
| 抗拉强度 | 260 – 350 MPA |
| 伸长 | ≥ 34 – 36% |
| 硬度 | 〜80 – 120 HB |
| 弹性模量 | 〜210 GPa |
