Fabrication of Hastelloy C-22
Although ductile enough to be formed by cold working, intermediate annealing may be necessary due to work hardening. Forging should be performed between 1750-2050°F followed by rapid cooling. Annealing can be performed at a temperature range between 2020-2150°F followed by a rapid quench. Cooling at an accelerated rate avoids the formation of detrimental phases which form between 1400-1800°F. Welding can be done by gas tungsten-arc, gas metal-arc and shielded metal-arc processes.
