Technical Data Sheet
Alloy 22 (UNS N06022) is the most versatile Nickel-Chromium-Molybdenum-Tungsten alloy with controlled Iron. Due to Alloy 22\’s content this alloy exhibits excellent resistance to both oxidising and reducing acid environments as well as those containing mixed acids. Alloy 22 is particularly useful for resistance to pitting and crevice corrosion in acid-halide environments. Alloy 22 is used in pickling chlorination, sulphonation plants, pollution control, chemical processing, marine and nuclear fuel reprocessing.
