Dx54D+AS120 Automotive Exhaust Tube: High-Performance Aluminized Steel Pipe for Exhaust Systems
Dx54D+AS120 automotive exhaust tube is a high-performance aluminized steel pipe designed specifically for vehicle exhaust systems. It is manufactured from Dx54D deep-drawing low-carbon steel and coated with an aluminum-silicon (Al-Si) alloy layer (AS120), providing excellent heat resistance, oxidation protection, and long service life under harsh engine conditions.
This material is widely used in passenger cars, commercial vehicles, motorcycles, and industrial exhaust assemblies where high-temperature stability and corrosion resistance are critical.
1. What Is Dx54D+AS120 Automotive Exhaust Tube?
| Item | Description |
|---|---|
| Base Material | Dx54D deep-drawing low carbon steel |
| Coating Type | Aluminum-Silicon (Al-Si) alloy coating |
| Coating Grade | AS120 (approx. 120 g/m² total coating weight) |
| Key Feature | High heat resistance and corrosion protection |
| Application Focus | Automotive exhaust systems |
2. Why It Is Ideal for Exhaust Systems
- High-temperature resistance: Performs under continuous exhaust heat exposure
