Hastelloy C-22
Common Trade Names: Hastelloy C22, Inconel 22, Nickel 22, Alloy 22, Nicrofer 5621
Hastelloy C-22 Alloy 22 designated as UNS N06022; Werkstoff No. 2.4602, NiCr21Mo14W is a fully austenitic advanced corrosion-resistant alloy that offers resistance to both aqueous corrosion and attack at elevated temperatures. This alloy provides exceptional resistance to general corrosion, pitting, crevice corrosion, intergranular attack, and stress corrosion cracking.
Properties:
- The alloy's high content of chromium gives it good resistance to wet corrosion by oxidizing media (e.g., nitric acid and ferric and cupric salts)
- Its contents of molybdenum and tungsten give the alloy resistance to wet reducing media (e.g., sulfuric and hydrochloric acids)
- Alloy 22 exhibits excellent resistance to corrosive attack by seawater under stagnant and flowing conditions.
- At elevated temperatures, the high chromium level of Hastelloy C-22 Alloy helps it resist oxidation, carburization, and sulfidation
- alloy 22 resists high temperature attack by halides (e.g., chlorides and fluorides)
Typical Applications:
- the alloy is widely used to protect steel tubes and other components in coal-fired and waste-to-energy boilers.
- Pharmaceutical industries use alloy C-22 fittings and tubing to avoid contamination caused by corrosion related failures
- Cellophane manufacturing
- Chlorination systems
- Pesticide production
- Incineration scrubber systems
- Chemical process industry in equipment like flue gas scrubbers, chlorination systems, sulfur dioxide scrubbers, pulp and paper bleach plants, pickling systems, and nuclear fuel reprocessing
- Waste water processing
Product Forms:
- Sheets, Strips, Plates
- Round Bars, Flat Bars, Hexagon
- Pipes, tubes, fittings and flanges
- Wires
