Hastelloy C-22 Chemical Composition:
Chromium (Cr): C-22 contains 22% chromium, a key element enhancing corrosion resistance by reacting with oxygen to form a thin, stable chromium oxide protective layer.
Nickel (Ni): 56% , Nickel increases the alloy's ductility, weldability, and formability while improving resistance to reducing acids, caustic solutions, and stress corrosion cracking.
Molybdenum (Mo): C-22 contains 13% Mo.
Molybdenum provides additional corrosion resistance in non-oxidizing conditions (e.g., hydrochloric and sulfuric acids), but typically leads to higher corrosion rates in oxidizing environments.
Tungsten (Tungsten): C-22 contains 4% tungsten. Tungsten primarily enhances the alloy's resistance to oxidation, nitriding, carburizing, halogenation, and stress corrosion cracking at elevated temperatures.
Hastelloy C-22: Due to its higher chromium content, C-22 offers broader corrosion resistance in both oxidizing and reducing environments, particularly in chloride-containing atmospheres, with superior resistance to localized corrosion such as pitting and crevice corrosion.
