TITANIUM GRADE 2
MATERIAL DESCRIPTION
Titanium Grade 2 is a pure alpha titanium. With moderate strength and excellent corrosion resistance and formability, Grade 2 titanium represents the most widely used form of titanium. Compared to the other grades of commercially pure titanium, Grade 2 titanium is slightly weaker than Grade 3, but stronger than Grade 1 and equally resistant to corrosion.
Titanium grade 2 is non-magnetic. These properties account for Grade 2 titanium’s versatility in regard to its applications.
Applications
This alloy 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.
Grade 2 titanium 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.
