Hastelloy C-22 Wire

Hastelloy C22 wire is the 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 hastelloy C-22 alloy wire exhibits superior weldability and is used as overalloy filler wireand weld overlay consumables to improve resistance to corrosion

Hastelloy C-22 alloy wire has better overall corrosion resistance than other Ni-Cr-Mo alloys available today, including Hastelloy C-276, C-4 alloys, and alloy 625. Hastelloy C-22 wire 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 tooccur 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.

C-22 alloy is available in most common product forms: plate, sheet, strip, billet, bar, wire, covered electrodes, pipe, and tubing.
