Description
Hastelloy C22 is a nickel-chromium-molybdenum solid solution strengthened super-alloy with a nominal chemical composition of 56% nickel, 22% chromium, and 13% molybdenum, with additions of iron, tungsten, and cobalt. It is commonly referred to by the tradename Hastelloy® C22 and the universal designation UNS N06022. C22 has excellent corrosion and oxidation resistance, great mechanical properties over a wide range of temperatures, and good fabrication properties.
CHARACTERISTICS:
CORROSION RESISTANCE
Hastelloy C22 is one of the most corrosion-resistant alloys available, even outperforming C276 and 625. It is resistant to almost all reducing and oxidizing environments, including strong oxidizers, seawater, and organic acids. In addition, C22 has excellent resistance to chloride-induced localized corrosion, including pitting, crevice corrosion, and stress corrosion cracking.
OXIDATION RESISTANCE
Hastelloy C22 has excellent resistance to oxidation, carburization, and sulfidation at elevated temperatures. However, C22 should not be used at temperatures above 1250°F due to the possible formation of embrittling phases.
MECHANICAL PROPERTIES
Hastelloy C22 is typically provided in the annealed condition with a minimum yield strength of 45 ksi. However, C22 can be cold worked to higher strength levels.
HEAT TREATMENT
Hastelloy C22 is typically annealed at 2050°F (1121°C), followed by rapid cooling.
WORKABILITY
Hastelloy C22 can be hot worked or cold worked. However, C22 work-hardens rapidly. Therefore, cold working must often be performed in stages with intervening anneals. Parts should be annealed after cold working.
