Sự miêu tả
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, linh kiện xây dựng, and other precision-formed metal parts.
thép DX54D belongs to the DX series in EN 10346 tiêu chuẩn, which are optimized for excellent ductility and stable forming performance.
1. What Is DX54D Steel?
thép DX54D 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. Thành phần hóa học (Thép cơ bản)
The steel substrate is designed to ensure high ductility and stable performance:
| Yếu tố | Nội dung (%) | Chức năng |
|---|---|---|
| Cacbon (C) | ≤ 0.12 | Maintains ductility |
| Mangan (Mn) | ≤ 0.60 | Cải thiện độ dẻo dai |
| Silicon (Và) | ≤ 0.50 | Controls steel structure |
| Phốt pho (P) | ≤ 0.10 | Hạn chế tạp chất |
| lưu huỳnh (S) | ≤ 0.045 | Cải thiện kiểm soát khả năng gia công |
| Nhôm (Al) | ≥ 0.015 | Khử oxy và tinh chế hạt |
| Nitơ (N) | ≤ 0.012 | Ổn định cấu trúc vi mô |
👉 Low carbon content is the key factor enabling excellent formability.
3. Tính chất cơ học
thép DX54D provides superior forming performance:
| Tài sản | Giá trị |
|---|---|
| Sức mạnh năng suất | 120 – 220 MPA |
| Độ bền kéo | 260 – 350 MPA |
| Độ giãn dài | ≥ 34 – 36% |
| độ cứng | ~80 – 120 HB |
| Mô đun đàn hồi | ~210 GPa |
👉 Tính năng chính: độ giãn dài rất cao + low yield strength = excellent deep drawing ability
