Alloy C22 N06022 overview
Hastelloy C-22 Alloy 22 (UNS N06022; W. Nr. 2.4602; NiCr21Mo14W) is a fully
austenitic advanced corrosion-resistant alloy that offers
resistance to both aqueous corrosion and attack at elevated
temperatures. This alloy provides exceptional resistance to general
corrosion, pitting, crevice corrosion, intergranular attack, and
stress corrosion cracking. Alloy 22 has found numerous applications
in the chemical/petrochemical processing, pollution control (flue
gas desulfurization), power, marine, pulp and paper processing, and
waste disposal industries.
Alloy 22 is nickel-base and typically contains 22% chromium, 14%
molybdenum, and 3% tungsten. Iron is normally limited to less than
3%. The alloy’s high content of chromium gives it good resistance
to wet corrosion by oxidizing media (e.g., nitric acid and ferric
and cupric salts). Its contents of molybdenum and tungsten give the
alloy resistance to wet reducing media (e.g., sulfuric and
hydrochloric acids). Alloy 22 exhibits excellent resistance to
corrosive attack by seawater under stagnant and flowing conditions.
