INCONEL® ALLOY C-22 (1.0402)
UNS N06022
W.Nr.1.0402
Diameter 2 - 75 mm
INCONEL® 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.
● Resistant to pitting, crevice corrosion and stress corrosion cracking
● Outstanding resistance to both reducing and oxidizing media
● Excellent resistance to oxidizing aqueous media
● Exceptional resistance to a wide variety of chemical process environments including strong oxidizers such as ferric acids, acetic anhydride, and seawater and brine solutions
● Resists the formation of grain-boundary precipitates in the weld heat-affected zone
● Excellent weldability
