Heat Resistant Dx54D+AS80 Tubing: Economical High-Temperature Aluminized Steel Pipe Overview
Heat resistant Dx54D+AS80 tubing is a cost-efficient aluminized steel pipe made from Dx54D deep-drawing low-carbon steel with an aluminum-silicon alloy coating (AS80). It is designed for applications requiring moderate heat resistance, oxidation protection, and reliable durability under thermal exposure.
Compared with higher coating grades such as AS120, AS80 offers a more economical solution while still maintaining stable performance in general heat-resistant industrial environments.
1. What Is Heat Resistant Dx54D+AS80 Tubing?
| Item | Description |
|---|---|
| Base Material | Dx54D deep-drawing low carbon steel |
| Coating Type | Aluminum-Silicon (Al-Si) alloy coating |
| Coating Grade | AS80 (approx. 80 g/m² total coating weight) |
| Key Feature | Heat resistance + cost efficiency |
| Product Form | Welded or formed steel tubing |
2. Heat Resistance Performance Characteristics
The AS80 aluminized coating provides a protective aluminum-rich layer that helps reduce oxidation and surface scaling when exposed to elevated temperatures.
- Reduces oxidation in moderate heat environments
- Improves thermal stability of steel surface
- Delays scaling and surface degradation
- Maintains structural integrity under thermal exposure
3. AS80 vs Higher Coating Grades
| Coating Type | Heat Resistance | Corrosion Resistance | Cost Level |
|---|---|---|---|
| AS80 | Moderate | Good | Economical |
| AS120 | High | Excellent | Higher |
| Galvanized Steel | Low | Medium | Low |
4. Key Advantages of Dx54D Base Steel
Dx54D steel provides excellent formability and ductility, making it suitable for tubing that requires bending, forming, or shaping during installation and manufacturing.
