UNS R50400 Titanium Tubing Applications
- For environments up to 300℃, this commercially pure titanium grade offers the best balance of strength and corrosion resistance.
- For higher temperatures (315–400℃), Grade 5 Ti-6Al-4V is recommended.
Q: What is the difference between Grade 1, Grade 2, and Grade 3 titanium?
All three are commercially pure titanium grades. Grade 1 offers the best formability, Grade 2 provides the best balance of strength and corrosion resistance, while Grade 3 offers higher strength but lower formability. For most industrial applications, Grade 2 is the preferred choice.
Titanium reacts rapidly with oxygen, nitrogen, and hydrogen at elevated temperatures. Proper argon shielding is essential to prevent contamination and maintain weld quality, ductility, and corrosion resistance.
ERTi-2 filler wire is commonly used when welding commercially pure titanium. GTAW (TIG welding) is the preferred process for achieving high-quality welds.
