English 
Hastelloy C22 provides resistance to general corrosion, pitting, crevice corrosion, intergranular attack, and stress corrosion cracking. Hastelloy C22 contains chromium, molybdenum, tungsten, and iron which makes the alloy resistant to corrosion in stagnant or flowing seawater. The alloy is formed by gas tungsten-arc, gas metal-arc, and shielded metal-arc processes.

CORROSION RESISTANCE
Alloy 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
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
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
C22 is typically annealed at 2050°F (1121°C), followed by rapid cooling.
WORKABILITY
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.
