ASTM B622 Hastelloy C22 Nickel Alloy Tube Round UNS N06022 Seamless Nickel Tubing
Description:
Hastelloy C-22 is extremely resistant to corrosion inoxidizing and reducing environments. C-22 has shownan outstanding resistance to a wide range ofchemicals, including chlorides, organic and inorganicsolutions.
Alloy 22 is nickel-base and typically contains 22% chromium, 14% molybdenum, and 3% tungsten. Iron is normally limited to less than 3%. 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.
Advantages:
1. Better overall corrosion resistance than Alloy C-276
2. Outstanding resistance to chloride pitting, crevice corrosion and stress corrosion cracking
3. Excellent resistance to oxidizing aqueous environments (wet chlorine and mixtures containing nitric acid and chloride ions)
Fabrications:
Although ductile enough to be formed by cold working, intermediate annealing may be necessary due to work hardening. Forging should be performed between 1750-2050° F followed by rapid cooling. Annealing can be performed at a temperature range between 2020-2150° F followed by a rapid quench. Cooling at an accelerated rate avoids the formation of detrimental phases which form between 1400-1800° F. Welding can be done by gas tungsten-arc, gas metal-arc and shielded metal-arc processes.
1. Pharmaceutical industries use alloy C-22 fittings and tubing to avoid contamination caused by corrosion related failures
2. Cellophane manufacturing
3. Chlorination systems
4. Pesticide production
5. Incineration scrubber systems
6. 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
7. Waste water processing
