Titanium 6AL-2SN - 4ZR-6MO
This is a heat treatable, alpha-beta alloy which was designed primarily for high temperature applications requiring higher strength than alloy 6-2-4-2 at similar temperatures. It combines good corrosion resistance and strength with weldability and fabricability. The alloy is generally available at the mill level in bar and billet form.

Market Applications
Generally selected over 6-2-4-2 for applications requiring strength at temperatures up to 454 C(850 F). Found in gas turbine discs and impellers and has been evaluated for use in deep sour well applications.
