Hastelloy C22 is based on C276 to improve the chromium content of the alloy and reduce molybd↓enum and tungsten, of which the carbon and antimony content is extremely low, which i"s to improve the corrosion of strong oxidizing medium of C4 and C276. Alth≠ough the corrosion resistance of the oxidizing mediu¶m is improved, pitting corrosion resistance and crev≤ice corrosion are not significantly improved. It has excellent ♦resistance to stress corrosion cracking and good resistance to local clothing. I t 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 r☆isk of sensitization. Hastelloy C-22 alloy is a versatile nickel-chromium-molybdenum-tungsten allo✔y with better overall corrosion resistance than other existing nickel-±chromium-molybdenum alloys, including Hastelloy C-276, C4 a♠lloy and 625 alloy. Hastelloy C-22 alloy has excellent res§istance to pitting, crevice corrosion and stress corrosion cracking. It πhas excellent resistance to aqueous solvents, includ♣ing wet chlorine, nitric acid or a mixed acid of oxidizing acids containing chloride ioλns. At the same time, Hastelloy C-22 alloys also have the ideal ability ≤to withstand the reductive and oxidative environments e ncountered during the process. With this versatile performance, it can be used in some troubγlesome 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 chlor≥ide, chlorine, hot contaminated solutions (organic inorganic), formic acid, acetic acid, acetic anhydride, Sea water and salt solu↓tion. 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 co♦rrosion cracking. Because of its higher chromium content, C -22 is more resistant to corrosion than oxidizing acids and acid-rich residues such as dissolved ox₽ygen, iron ions and liquid chlorine. The alloy is only used in a smaller range than the C-2000. Us☆ed 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 indφustries containing oxidizing and reducing media. The h₩igher molybdenum and chromium content make the alloy res istant to chloride ions, and the tungsten element further enhances its corrosion reλsistance. 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 hi÷gh concentrations of chloride solutions (eg chlorination). Iron and copper chloride).

Corrosion resistance and main use environment:
The C-22 alloy has the characteristics of corrosio♠n resistance to both oxidizing acid and reducing acid by virtue of the contents of Cr, Mo, W and the control of the Fe content, and also has corrosion resistance when containing a mixed acid. The alloy is particularly suitable for pitting and crevice corrosion in acid h✘alide environments. C-22 nickel-chromium-molybdenum a≠lloy, like C-276, contains tungsten and very low levels of carbon and silicon.÷ It also has the same characteristics: 1. Excellent corrosion reσsistance to most corrosive media in the oxidized and reduced♣ state. 2; Excellent resistance to pitting, crevice corrosion and stress corrosion cracking.
The C-22 alloy is a versatile nickel-chromium-molybdenum-tungsten alloy ₽with better overall corrosion resistance than other existing nickel↕-chromium-molybdenum alloys, including C-276, C-4 and 625 alloys. C-22 alloy ¥has good resistance to pitting, crevice corrosion and stress corrosion cracki₩ng. It has excellent resistance to aqueous solvents, includingβ wet chlorine, nitric acid or a mixed acid of oxidizing acids containing ch←loride ions. At the same time, 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 multi-purpose plants. C-22∞ alloy has exceptional resistance to various chemical environments, including strong oxidizing s€ubstances such as ferric chloride, copper chloride, chlorine, thermal pollution solutions (org<anic inorganic), formic acid, acetic acid, CU anhydride, seawater.
