Commercially referred to as the "workforce" of the pure titanium industry due to its diverse availability and wide availability. It shares many of the same qualities as Grade 1 titanium, but is slightly stronger. Both are equally corrosion resistant. This grade has good weldability, strength, ductility and formability. Titanium Grade 2 material makes bar and sheet the primary choice for many application areas:
It is used in the fields of Aviation, Automotive, Chemical Processing and Chlorate Production, Desalination, Architecture, Hydro-Carbon Processing, Marine, Medical, Energy Generation.
