HASTELLOY C22
Hastelloy C-22 has exceptional resistance to a wide variety of chemical process environments, including strong oxidizers such as ferric and cupric chlorides, hot contaminated media (organic and inorganic), chlorine, formic and acetic acids, acetic anhydride, and seawater amd brine solutions.
Hastelloy C-22 resists the formation of grain boundary precipitates in the weld heat affected zone, thus making it suitable for most chemical process applications in the as-welded condition.
