Grade 1. Pure Titanium, relatively low strength and high ductility. Grade 2. The pure titanium most used. The best combination of strength, ductility and weldability. Grade 3. High strength Titanium, used for Matrix-plates in shell and tube heat exchangers. Grade 5. The most manufactured titanium alloy. Exceedingly high strength. High heat resistance. Grade 7. Superior corrosion resistance in reducing and oxidizing environments. Grade 9. Very high strength and corrosion resistance.
