Hastelloy C-22 (UNS No. N06022)
Hastelloy C-22 also known as Alloy C-22, is a versatile nickel-chromium-molybdenum alloy with better overall corrosion resistance than other Ni-Cr-Mo alloys available today. Alloy C-22 has outstanding resistance to pitting, crevice corrosion and stress corrosion cracking. It has excellent resistance to oxidizing aqueous media including acids with oxidizing agents, wet chlorine and mixtures containing nitric acid or oxidizing acids with chlorine ions. Hastelloy C-22 has outstanding resistance to both reducing and oxidizing media, and because of its versatility it can be used multipurpose plants where "upset" conditions occur frequently. 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), oxidizing acid chlorides, wet chlorine, formic and acetic acids, ferric and cupric chlorides, acetic anhydride, sea water and brine and many mixed or contaminated chemical solutions, both organic and inorganic.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. Hastelloy C-22 is approved for construction of pressure vessels and components under ASME Boiler and Pressure Vessel Code for service up to 1250° F. Nano-Mag Technologies offer various products made from Hastelloy C-22 material including High Pressure Autoclave, Reactor, Hydrogenators, Magnetic Drives, Catalyst Filters etc. as per the requirement.
We also supply all types of Corrosion coupons in various size, custom made size, surface finish, stamped with serial number.
