ASTM B575 is a specification for HASTELLOY C276 & C22 Sheet
Hastelloy C276 (UNS N10276) is an austenitic nickel-molybdenumchromium alloy with a small addition of tungsten. It is one of the premier corrosion resistant materials available for process industries. Hastelloy C276 has excellent corrosion resistance in both oxidizing and reducing environments.
Hastelloy C22 (UNS N06022) is the most versatile Nickel-Chromium-Molybdenum-Tungsten alloy with controlled Iron. Hastelloy C22 contents exhibit excellent resistance to both oxidising and reducing acid environments as well as those containing mixed acids. Hastelloy C22 is particularly useful for resistance to pitting and crevice corrosion in acid-halide environments. Hastelloy C22 is used in pickling chlorination, sulphonation plants, pollution control, chemical processing, marine and nuclear fuel reprocessing.
Hastelloy C276 and C22 per ASTM B575 sheet Thicknesses range from 0.002″ to .150″ Thick.
