Alloy 22 is a Nickel-Chromium-Molybdenum alloy otherwise known as Inconel®. It 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 exhibits excellent resistance to corrosive attack by seawater under stagnant and flowing conditions.
When Inconel® is heat treated it creates a thick, stable layer of oxide around itself meaning it can be used in high temperature environments because of its heat resistance. Inconel® also has a high resistance to corrosion and pressure which makes it a perfect candidate for most aerospace, marine and chemical industries. Inconel® has many applications in the chemical/petrochemical processing, pollution control (flue gas desulfurisation), power, marine, pulp and paper processing and waste disposal industries.
