Features: Hastelloy C-22 is a versatile Ni-Cr-Mo-W alloy with better
comprehensive corrosion resistance performance than other Ni-Cr-Mo
alloys, including Hastelloy C-276, Hastelloy C-4 and Inconel 625.
Hastelloy C-22 has outstanding resistance to pitting, crevice
corrosion and stress corrosion cracking. It has excellent
resistance to oxidizing aqueous media including wet chlorine and
mixtures containing nitric acid or oxidizing acids with chloride
ions. It also offers optimum resistance to environments where
reducing and oxidizing conditions are encountered in process
streams. So it can be used where “upset” conditions are likely to
occur or in multi-purpose plants. Hastelloy C-22 has exceptional
resistance to a wide variety of chemical process environments,
including strong oxidizers such as ferric and cupric chlorides,
chlorine, hot contaminated solutions (organic and inorganic),
formic and acetic acids, acetic anhydride, and seawater and brine
solutions. It resists the formation of grain boundary precipitates
in the weld heat-affected zone, thus making it suitable for most
chemical process applications in the as-welded condition.
Applications: Chemical processing involving acetic acid, acetic
anhydride and complex acid mixture; pickling operations; cellophane
manufacture; chlorination systems; electro-galvanizing rolls,
expansion bellows; flue gas scrubber systems; geothermal wells; HF
furnace scrubbers; incineration scrubbers; nuclear fuel
reprocessing; pesticide production; phosphoric acid production;
heat exchangers; selective leaching systems; sulfur dioxide cooling
towers; sulphonation systems; and weld overlay.
