Haynes Hastelloy® C-22® alloy, 6.4-19.1 mm thick plate, solution heat treated

HASTELLOY® C-22® alloy is a nickel-chromium-molybdenum-tungsten alloy with excellent overall corrosion resistance compared to other Ni-Cr-Mo alloys, 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. 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.Applications: Acetic Acid/Acetic Anhydride Acid Etching Cellophane Manufacturing Chlorination Systems Complex Acid Mixtures Electro-Galvanizing Rolls Expansion Bellows Flue Gas Scrubber Systems Geothermal Wells HF Furnace Scrubbers Incineration Scrubber Systems Nuclear Fuel Reprocessing Pesticide Production Phosphoric Acid Production Pickling Systems Plate Heat Exchangers Selective Leaching Systems SO2 Cooling Towers Sulfonation Systems Tubular Heat Exchangers Weld Overlay-Valves Data provided by the manufacturer, Haynes International, Inc.
