Inconel 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. Inconel alloy 22 provides exceptional resistance to general corrosion, pitting, crevice corrosion, intergranular attack, and stress corrosion cracking. Inconel 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. Inconel 22 is nickel-base and typically contains 22% chromium, 14% molybdenum, and 3% tungsten. Iron is normally limited to less than 3%.
Inconel 22 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). Inconel Alloy 22 exhibits excellent resistance to corrosive attack by seawater under stagnant and flowing conditions. At elevated temperatures, the high chromium level of Inconel alloy 22 helps it resist oxidation, carburization, and sulfidation. Since it is nickel-base, Inconel alloy 22 resists high temperature attack by halides (e.g., chlorides and fluorides). With these attributes, Inconel alloy 22 is widely used to protect steel tubes and other components in coal-fired an waste-to-energy boilers.
