Titanium Properties
Grade 2 is the most frequently used unalloyed titanium grade. It provides moderate strength (typical yield strength 352 MPa) combined with good ductility and formability and excellent weldability. Grade 2 titanium has a density of 4.51 g/cc - less than 60% that of steel.

Suitable For
Grade 2 is primarily use for corrosion resistance and is the most widely used specification in all product forms. Grade 2 titanium proves useful in chemical processes, since it is highly resistant to chemical environments including oxidizing media, alkaline media, organic acids and compounds, aqueous salt solutions and hot gases. Its corrosion resistance holds up in liquid metals, nitric acid, mildly reducing acids and wet chlorine or bromine gas.
Remarks
Titanium Grade 2 is also used to manufacture heat exchangers and cryogenic vessels. In seawater, Grade 2 is fully resistant to corrosion at temperatures up to 300°C.
