Hastelloy® C-22 (UNS N06022) is a nickel-chromium-molybdenum-tungsten alloy, offering exceptional corrosion resistance compared to all other Ni-Cr-Mo alloys. Hastelloy® C-22 powders are used in aggressive environments in the chemical processing and oil and gas sectors.
Key Benefits of Hastelloy® C22
With high chromium content, Hastelloy® C-22 offers superior resistance to oxidizing chemicals, surpassing the C-276 alloy. Its outstanding resistance to chloride-induced pitting and excellent performance in harsh environments—such as wet chlorine, formic and acetic acids, seawater, and various complex chemical solutions—make it highly versatile. Additionally, C-22 is ductile, weldable, and easily fabricated into industrial components.
Hastelloy® C22 Powder Applications
Our C-22 powders are used for industrial filters, thermal spray and cladding coatings, and to make sintered parts. Key properties include exceptional resistance to chloride pitting, crevice corrosion, stress corrosion cracking, and protection in both oxidizing and non-oxidizing conditions, making it well suited for extreme environments.
