Описание
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, строительные компоненты, and other precision-formed metal parts.
Сталь DX54D belongs to the DX series in EN 10346 стандарты, which are optimized for excellent ductility and stable forming performance.
1. What Is DX54D Steel?
Сталь 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. Химический состав (Базовая сталь)
The steel substrate is designed to ensure high ductility and stable performance:
| Элемент | Содержание (%) | Функция |
|---|---|---|
| Углерод (С) | ≤ 0.12 | Сохраняет пластичность |
| Марганец (Мин.) | ≤ 0.60 | Улучшает прочность |
| Кремний (И) | ≤ 0.50 | Управляет стальной конструкцией |
| Фосфор (П) | ≤ 0.10 | Ограничивает примеси |
| сера (С) | ≤ 0.045 | Улучшает контроль обрабатываемости |
| Алюминий (Ал) | ≥ 0.015 | Раскисление и измельчение зерна |
| Азот (Н) | ≤ 0.012 | Стабилизирует микроструктуру |
👉 Low carbon content is the key factor enabling excellent formability.
3. Механические свойства
Сталь DX54D provides superior forming performance:
| Свойство | Ценить |
|---|---|
| Предел текучести | 120 – 220 МПа |
| Предел прочности | 260 – 350 МПа |
| Удлинение | ≥ 34 – 36% |
| Твердость | ~80 – 120 полупансион |
| Модуль упругости | ~210 ГПа |
👉 Ключевая особенность: очень высокое удлинение + low yield strength = excellent deep drawing ability
