Tungstate based corrosion inhibitors

A trace amount of a tungstate is disclosed for inhibiting corrosion by nitrogen fertilizer solution, in particular, an ammonium nitrate fertilizer solution, (UAN) in contact with ferrous metal storage tanks, piping, and equipment surfaces. Tungstate added with a dispersant polymer is also effective for inhibiting corrosion.
