UNS Number R50400

Titanium Grade 2 is unalloyed Titanium with standard Oxygen. It is called the “workhorse” of the commercially pure titanium industry, thanks to its varied usability and wide availability. It possesses good weldability, strength, ductility and formability.

Machining and Fabrication with Titanium Grade 2:

Titanium Grade 2 has good ductility, which allows for cold formability. The minimum bend radius for material under 0.070″ thick should be 2T while 2.5T
should be used for material over 0.070″. The material can also be easily machined, hot worked
and welded. Hot working should be performed between 400°F
and 600°F. Stress relieving should be performed by heating to a temperature between 900°F and 1100°F followed by either forced air or slow cooling.
Welding of Grade 2 titanium can be done using various methods such as MIG and TIG. Inert gas shielding is crucial to prevent oxygen pickup and embrittlement of the weld area. A mixture of argon and helium is typically preferred but should be proven before accepting a procedure. Preheat or post heat treatments are not required.
