ASTM B338 Alloy Gr7 Titanium Pipe
High-strength Gr 2 Gr 5 Gr 7 Titanium Plate
Products Description
Titanium Grade 7 is mechanically and physically equivalent to Titanium Grade 2, with the exception of additional interstitial palladium which makes this material alloy. Grade 7 demonstrates excellent weldability, fabricability, and is the most corrosion resistance of all titanium alloys. Because of these traits, this material is often used in chemical production processes and applications within the production equipment.
