Hastelloy C22 is based on C276 to improve the chromium content of the alloy and reduce molybdenum and tungsten, of which the carbon and antimony content is extremely low, which is to improve the corrosion of strong oxidizing medium of C4 and C276. Although the corrosion resistance of the oxidizing medium is improved, pitting corrosion resistance and crevice corrosion are not significantly improved. It has excellent resistance to stress corrosion cracking and good resistance to local clothing. It has satisfactory corrosion resistance in many chemical process media. Because of its extremely low carbon and niobium, it is very suitable for corrosion-resistant welding in the chemical industry. Equipment, containers, pipelines without the risk of sensitization. Hastelloy C-22 alloy is a versatile nickel-chromium-molybdenum-tungsten alloy with better overall corrosion resistance than other existing nickel-chromium-molybdenum alloys, including Hastelloy C-276, C4 alloy and 625 alloy. Hastelloy C-22 alloy has excellent resistance to pitting, crevice corrosion and stress corrosion cracking. It has excellent resistance to aqueous solvents, including wet chlorine, nitric acid or a mixed acid of oxidizing acids containing chloride ions. At the same time, Hastelloy C-22 alloys also have the ideal ability to withstand the reductive and oxidative environments encountered during the process. With this versatile performance, it can be used in some troublesome environments or in a variety of production plants. Hastelloy C-22 alloy has exceptional resistance to a variety of chemical environments, including strong oxidizing substances such as ferric chloride, copper chloride, chlorine, hot contaminated solutions (organic inorganic), formic acid, acetic acid, acetic anhydride, Sea water and salt solution. Hastelloy C-22 alloy has the ability to resist the formation of grain boundary precipitates in the heat affected zone of the weld, so that it can be adapted to many chemical processes in the welded state.

Hastelloy C-22 Material Description:
C-22 alloys have outstanding resistance to pitting, seam corrosion and stress corrosion cracking. Because of its higher chromium content, C-22 is more resistant to corrosion than oxidizing acids and acid-rich residues such as dissolved oxygen, iron ions and liquid chlorine. The alloy is only used in a smaller range than the C-2000. Used in most corrosive environments and most complex pharmaceutical reactors for flue gas desulfurization systems.
Hastelloy C-22 corrosion resistance:
The alloy is suitable for use in a variety of chemical process industries containing oxidizing and reducing media. The higher molybdenum and chromium content make the alloy resistant to chloride ions, and the tungsten element further enhances its corrosion resistance. Hastelloy C-22 is one of only a few materials that are resistant to the corrosion of moist chlorine, hypochlorite and chlorine dioxide solutions. The alloy has significant corrosion resistance to high concentrations of chloride solutions (eg chlorination). Iron and copper chloride).
