Hastelloy C-22
A most versatile nickel-chromium-molybdenum-tungsten alloy
available today with improved resistance to both uniform and localized
corrosion as well as to a variety of mixed industrial chemicals. The C-
22 alloy exhibits superior weldability and is used as overalloy filler wire
and weld overlay consumables to improve resistance to corrosion
HASTELLOY C-22 alloy is a versatile nickel-chromium- molybdenum-
tungsten alloy with better overall corrosion resistance than other Ni-Cr-
Mo alloys available today, including HASTELLOY C-276 and C-4 alloys
and alloy 625. C-22 alloy 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. Also, C-22
alloy offers optimum resistance to environments where reducing and
oxidizing conditions are encountered in process streams. Because of
such versatility it can be used where “upset” conditions are likely to
occur or in multi-purpose plants.
C-22 alloy 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. C-22 alloy 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.
Product Forms
C-22 alloy is available in most common product forms: plate, sheet,
strip, billet, bar, wire, covered electrodes, pipe, and tubing.
Specifications
UNS N06022
Plate, sheet, strip, bar, tubing, and pipe are covered by ASME
specifications SB-574, SB-575, SB-619, SB-622 and SB-626 and by
ASTM specifica-tions B-574, B-575, B-619, B-622, and B-626. DIN
specification is 17744 No. 2.4602 (all forms), TUV Werkstoffblatt 479
(all forms). NACE specification is MR-01-75. C-22 alloy falls within the
range of UNS number N06022 but has a more restricted composition
for improved performance. These improvements are of such
significance that it has been widely patented throughout the world.
