EN 10346 Dx54D+AS120 Welded Pipe: European Standard Aluminized Steel Tube Overview
EN 10346 Dx54D+AS120 welded pipe is a European standard aluminized steel tube produced from deep-drawing grade low-carbon steel (Dx54D) with an aluminum-silicon alloy coating (AS120). It is designed for high corrosion resistance, excellent formability, and stable performance in thermal and automotive environments.
This welded pipe structure combines the cost efficiency of ERW welding with the protective benefits of aluminized coating, making it widely used in exhaust systems, heat exchangers, HVAC pipelines, and industrial fluid transfer systems.
1. What Is EN 10346 Dx54D+AS120 Welded Pipe?
| Item | Description |
|---|---|
| Standard | EN 10346 European standard |
| Base Material | Dx54D deep-drawing low carbon steel |
| Coating Type | Aluminum-Silicon alloy coating |
| Coating Weight | AS120 (approx. 120 g/m²) |
| Manufacturing Method | ERW welded pipe (electric resistance welded) |
| Main Feature | High corrosion resistance + excellent formability |
2. Performance Advantages
- Excellent corrosion resistance: Al-Si coating protects against oxidation and moisture
- High-temperature stability: Suitable for exhaust and heat exposure systems
- Good weldability: ERW structure ensures stable seam performance
- Strong formability: Dx54D steel supports bending, stamping, and deep drawing
According to EN 10346 aluminized steel specifications, Dx54D grade offers a yield strength of about 120–220 MPa and tensile strength of 260–350 MPa, making it suitable for deep-forming applications. :contentReference[oaicite:0]{index=0}
3. Common Applications
| Industry | Application |
|---|---|
| Automotive | Exhaust pipes, emission ducts, ventilation tubes |
| HVAC systems | Air distribution pipes and heat exchange tubes |
| Industrial equipment | Thermal pipelines and protective tubing |
| Construction | Light structural piping systems |
4. Why AS120 Coating Matters
The AS120 aluminum-silicon coating forms a dense protective layer that improves oxidation resistance and prevents surface scaling under high-temperature conditions. It is especially suitable for exhaust and thermal systems where conventional galvanized steel cannot perform well.
- Improves high-temperature oxidation resistance
- Reduces corrosion in humid environments
- Extends service life of welded pipe systems
- Enhances surface stability under thermal cycling
