In what applications is Hastelloy C22 used?

• Pharmaceutical industries use alloy C-22 fittings and tubing to avoid contamination caused by corrosion related failures

• Cellophane manufacturing

• Chlorination systems

• Pesticide production

• Incineration scrubber systems

• Chemical process industry in equipment like flue gas scrubbers, chlorination systems, sulfur dioxide scrubbers, pulp and paper bleach plants, pickling systems, and nuclear fuel reprocessing

• Waste water processing

 

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.
