  • Features

Hastelloy C-22 is a versatile Ni-Cr-Mo-W alloy with better comprehensive corrosion resistance performance than other Ni-Cr-Mo alloys, including Hastelloy C276, Hastelloy C4 and Inconel 625. Hastelloy C-22 has a outstanding resistance to pitting, crevice corrosion and stress corrosion cracking. It has a excellent resistance to oxidizing aqueous media including wet chlorine , mixtures containing nitric acid or oxidizing acids with chloride ions. Hastelloy C22 also offers optimum resistance to environments oxidiic conditions. With these feature, Hastelloy C22 can be used in hostile conditions. Hastelloy C-22 also has exceptional resistance to a wide variety of chemical process environments, such as ferric and cupric chlorides, chlorine, hot contaminated solutions (organic and inorganic), formic and acetic acids, acetic anhydride, and seawater and brine solutions. It 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.
