Products Description
Our Advantages
1. Standards and Certifications
Our 2.5 3 4 Titanium Exhaust Tubing is guaranteed to comply with ASTM B338 standards and is certified by ISO 9001, TUV, and MTC.
2. High-Temperature Strength
Our 2.5 3 4 Titanium Exhaust Tubing maintains excellent mechanical properties at temperatures up to 600°C (1110°F) without deformation or embrittlement, making it ideal for racing, aircraft, and turbocharged exhaust systems. Mechanical property test reports are available.
3. Welding Quality
Our tubing is produced using TIG welding and laser welding to ensure clean and high-quality welds. Post-weld pickling and passivation ensure corrosion resistance. Each welded tube undergoes rigorous quality testing to ensure weld quality.
4. Surface Treatment
The tubing undergoes a pickling and passivation treatment to form a passive film, enhancing chemical and environmental corrosion resistance. The inner surface of the steel tubing is mechanically polished to reduce friction and flow resistance, improving exhaust gas flow efficiency.
application areas
- Automotive and Motorsports: High-performance exhaust systems, lightweight roll cages and structural components, turbine downpipes, headers, and mid-pipes.
- Motorcycle Exhaust Systems: Custom exhaust pipe fabrication for racing and stunt motorcycles.
- Aerospace: Lightweight ducting for exhaust piping and auxiliary systems.
- Marine: Exhaust pipes for high-performance boats and yachts.
- Industrial and High-Temperature Systems: Heat exchangers, condensers, and process piping.

Mechanical Properties
| Grade | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Density (g/cm³) |
| Grade 2 | ≥ 345 | ≥ 275 | ≥ 20 | 4.51 |
| Grade 11 | ≥ 275 | ≥ 240 | ≥ 24 | 4.51 |
| Grade 16 | ≥ 345 | ≥ 275 | ≥ 20 | 4.51 |
Possible Alternative Grades
| Alternative Grades | Reasons |
| Grade 5 Titanium Alloy | Significantly stronger than commercially pure titanium alloys (Grades 2, 11, and 16). Recommended for high-performance construction requiring extreme strength and stiffness. |
| Grade 7 Titanium Alloy | A palladium-stabilized alloy with excellent corrosion resistance, ideal for marine or highly corrosive environments. |
| Inconel 625/718 | A high-performance nickel alloy suitable for very high-temperature applications (such as turbine manifolds), where extreme heat resistance is more important than weight reduction. |
