Typical use
C- 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 C- 22 is particularly useful for resistance to pitting and crevice corrosion in acid-halide environments. Alloy C-22 is used in pickling chlorination, sulphonation plants, pollution control, chemical processing, marine and nuclear fuel reprocessing.
