UNS N06022 is a nickel-chromium-molybdenum-tungsten alloy that is known by its trade name "Hastelloy C-22." It is a corrosion-resistant alloy that exhibits excellent resistance to a wide range of corrosive environments, including oxidizing and reducing conditions.
Hastelloy C22 is often used in applications involving harsh chemical environments, such as chemical processing, pollution control, pulp and paper production, waste treatment, and more. Alloy C22 composition provides it with exceptional resistance to both pitting and crevice corrosion, making it suitable for use in chloride-containing environments.
The specific composition can vary slightly based on the manufacturer and the specific requirements of the application. The combination of these elements gives Hastelloy C-22 its impressive corrosion resistance properties.
The composition of UNS N06022 (Hastelloy C-22) typically includes the following elements:
- Nickel (Ni): Approximately 56%
- Chromium (Cr): Approximately 22%
- Molybdenum (Mo): Approximately 13%
- Tungsten (W): Approximately 3%
- Iron (Fe): Maximum of 3%
- Cobalt (Co): Maximum of 2.5%
- Other trace elements
