Hastelloy® C-22
·UNS Number N06022
·Other common names: Alloy C22
Hastelloy C22, also known as alloy C22, is a versatile austenitic nickel-chromium-molybdenum-tungsten alloy with enhanced resistance to pitting, crevice corrosion and stress corrosion cracking. The high chromium content provides good resistance to oxidizing media while the molybdenum and tungsten content give good resistance to reducing media. This nickel steel alloy also has excellent resistance to oxidizing aqueous media including wet chlorine and mixtures containing nitric acid or oxidizing acids with chlorine ions.
What are the characteristics of Hastelloy C22?
·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

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.
