Dx53d Z100
DX53D Z100 is a high-formability galvanized steel combining:
- Low-carbon deep drawing steel (DX53D)
- Zinc coating protection (Z100 ~100 g/m²)
Its key advantages include:
- 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.
- Description
Description
DX53D Z100 is a hot-dip galvanized deep-drawing steel that combines a low-carbon steel substrate with a zinc coating of approximately 100 g/m² (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 galvanized steel 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 g/m² (both sides total coating weight system depending on standard)
- Base standard → EN 10346 hot-dip galvanized steel system
So, 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:
| Element | Content (%) | Function |
|---|---|---|
| Carbon (C) | ≤ 0.10–0.12 | Improves strength, keeps good ductility |
| Silicon (Si) | ≤ 0.50 | Controls oxidation behavior |
| Manganese (Mn) | ≤ 0.60 | Improves toughness |
| Phosphorus (P) | ≤ 0.10 | Limited impurity control |
| Sulfur (S) | ≤ 0.045 | Improves machinability control |
| Aluminum (Al) | ≥ 0.015 | Deoxidation and grain control |
| Nitrogen (N) | ≤ 0.012 | Stabilizes structure |
👉 This composition ensures high elongation and excellent deep drawing ability.
3. Zinc Coating Composition (Z100 Layer)
The Z100 coating refers to a hot-dip zinc layer:
| Component | Description |
|---|---|
| Zinc (Zn) | Main protective layer |
| Iron-Zinc intermetallic layer | Bonding layer between steel and coating |
| Coating mass | ~100 g/m² total |
The coating forms a metallurgical bond, not just a surface layer, which improves durability.
4. Mechanical Properties of DX53D Z100
DX53D steel provides excellent forming performance:
| Property | Value |
|---|---|
| Tensile Strength | 270 – 380 MPa |
| Yield Strength | 140 – 260 MPa |
| Elongation | ≥ 28 – 40% |
| Hardness | ~80 – 120 HB |
| Elastic Modulus | ~210 GPa |
👉 Key feature: very high elongation + low yield strength → excellent forming capability
5. Physical and Functional Properties
- Excellent deep drawing performance
- Good weldability (spot & arc welding)
- Strong corrosion resistance due to zinc coating
- Good surface quality for painting or coating
- Stable mechanical behavior during stamping
6. Role of Zinc Coating (Z100)
The Z100 coating provides:
Corrosion Protection
- Sacrificial protection (zinc corrodes first)
- Suitable for indoor and mild outdoor environments
Surface Barrier
- Blocks moisture and oxygen
- Extends service life of steel components
Formability Compatibility
- Coating remains stable during moderate forming operations
7. Common Applications of DX53D Z100
DX53D galvanized steel is widely used in:
- Automotive body panels
- Refrigerator and washing machine shells
- Electrical cabinets
- HVAC duct systems
- Light steel structures
- Appliance internal parts
- Formed metal housings
