Hastelloy C22 Alloy

HASTELLOY® alloys are known throughout the world as the premier corrosion-resistant alloys. These alloys have been used in severe process environments such as those encountered in the chemical process industry, metal pickling facilities, flue gas desulfurization scrubbers, electronics manufacturing, nuclear fuel reprocessing, and in a wide variety of hazardous waste management technologies where high corrosion-resistance of critical equipment is required for reliability, safety, and cost effectiveness/reduced maintenance.


HASTELLOY® C-22® alloy has also been used successfully as scrubber components for hospital waste, municipal waste and spent solvent incineration as well as in a variety of industrial incinerators.

Other pollution control technologies which utilize C-22® alloy include critical fluid extraction process equipment, process piping and vessels for waste-water treatment ion exchange resin rejuvenation systems, flue gas desulfurization scrubbers at coal fired utilities (Figure 6), and spent acid reclamation vessels.
