WIRE - Hastelloy^® C-22

Hastelloy® C-22® Wire Alloy (UNS N06022)

If you need wire to work in highly corrosive or extreme temperature situations, consider utilizing HASTELLOY® C-22® wire for the job. The Nickel-Chromium-Molybdenum-Tungsten alloy is one of the most corrosion resistant alloys on the market and can withstand almost any extreme circumstance it is needed to perform in. Furthermore, besides general corrosion, it is also resistant to pitting and stress corrosion cracking. It can withstand very high temperatures such as when sulfur is present in a coal power production plant, and can withstand corrosion where solid waste might be found such as a boiler or containment unit.

HASTELLOY® C-22® wire alloy is very weldable and easily formed. It does not matter if you are using a gas tungsten arc, a shielded metal, or gas metal arc, this alloy can adapt to any method. This is because it naturally prevents the development of grain boundary precipitates. This is not always the case with other alloys, which makes C-22® very versatile, and the ideal wire for situations where an irregularly shaped device must be used in an area that would be too corrosive for normal wiring.The practical uses for HASTELLOY® C-22® alloy include areas where nitric, formic and ferric acids are present. Also areas that may have wet or cupric chlorides which will normally destroy other alloys in a relatively short period of time. This is why industries such as chemical processing, sea water industrial equipment, and nuclear fuel processing use HASTELLOY® C-22® for many of their wiring needs. These industries cannot afford to have wiring fail due to the extreme nature of the environment which is extremely hazardous for humans to do maintenance in.

However, with C-22®, these concerns go out the window.The element that sets C-22® apart from other alloys is the trace amounts of Vanadium in the wire itself. Vanadium is often used to enhance the properties that most metals already show. Therefore, one you are dealing with one of the 12 corrosion-resistant alloys under the Hastelloy^® brand, all of which show enhanced levels of corrosion resistance, the Vanadium combines with the Nickel, Chromium, Molybdenum, and Tungsten to make an alloy that takes this characteristic to extreme levels.
