Description
Hastelloy C-22 is a versatile nickel-chromium-molybdenum alloy with
better overall corrosion resistance than other Ni-Cr-Mo alloys
available today, including hastelloy C-276, C-4, and A625. Alloy
C-22 has outstanding resistance to pitting, crevice corrosion and
stress-corrosion cracking. It has excellent resistance to oxidizing
aqueous media including acids with oxidizing agents, wet chlorine
and mixtures containing nitric acid or oxidizing acids with
chlorine ions. Hastelloy C-22 has outstanding resistance to both
reducing and oxidizing media, and because of its versatility can be
used where "upset" conditions are likely to occur or in
multipurpose plants.
Workability
Hastelloy C-22 can be fabricated using the same techniques as are
used for alloys C-276 or C-4. It can be welded, forged, hot-upset
and impact extruded. Alloy C-22 can also be successfully
deep-drawn, spun, press formed or punched, although the alloy tends
to work-harden.
Parts which have been hot formed or severely cold formed should be
heat treated at 2050 °F and rapid quenched prior to final
fabrication or installation.
Application
Some of the area of present or potential use for Hastelloy C-22
are: Acetic acid/Acetic Anhydride, cellophane manufacturing,
chlorine spargers, chlorination systems, circuit board etching
equipment, complex acid/chemical mixtures, fans and blowers,
galvanizing line equipment, gas scrubber systems, geothermal wells,
HF furnaces, incineration systems, nuclear fuel reprocessing,
pesticide production, phosphoric acid applications, pickling system
components, plate heat exchangers, selective leaching systems,
sulfur oxide cooling towers, sulfonation systems, and tubular heat
exchangers.
