What is a GR12 titanium tube?
Titanium Alloy Grade 12 has outstanding corrosion resistance and a combination of high strength and low density, with good ductility. Small additions of nickel and molybdenum have been made to this alloy resulting increase in corrosion resistance and high strength. It is particularly suitable for use in mildly reducing conditions, or where conditions vary from oxidising to reducing. It is particularly resistant to crevice corrosion in hot brines.
Typical Applications
Many of the applications of grade 12 titanium alloy are in the chemical industries. The common uses are in chemical processing, where titanium alloy grade 12 is used for reactor autoclaves, piping and fittings, valves, heat exchanges and condensers.

Corrosion Resistance of Titanium Alloy
Titanium alloys are usually used in Australia for their excellent corrosion resistance, especially to chloride solutions. The small additions of nickel and molybdenum to grade 12 titanium give a more corrosion resistant metal than the commercial purity grade 2 alloy, with a marked increase in strength. The overall corrosion resistance of this grade is not as good as the palladium alloyed lean grade 7, except for resistance to crevice corrosion in hot chloride solutions. Titanium has excellent resistance to general corrosion, with loss rates of less than 0.04mm/year being typical.
