Shanghai Metal Corporation is a professional manufacturer and supplier of Hastelloy C22 products with high quality and reasonable price.
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 C-276, Hastelloy C-4 and Inconel 625. Hastelloy C-22 has outstanding resistance to pitting, crevice corrosion and stress corrosion cracking. It has excellent resistance to oxidizing aqueous media including wet chlorine and mixtures containing nitric acid or oxidizing acids with chloride ions.
If you want to know more about price of Hastelloy C22 products, please feel free to contact us, we will reply you within 24 hours.
Hastelloy C-22 has exceptional resistance to a wide variety of chemical process environments, including strong oxidizers such as ferric and cupric chlorides, chlorine, formic and acetic acids, acetic anhydride 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.
Chemical processing involving acetic acid, acetic anhydride and complex acid mixture; HF furnace scrubbers; incineration scrubbers; nuclear fuel reprocessing; pesticide production; phosphoric acid production; heat exchangers; selective leaching systems; sulfur dioxide cooling towers; sulphonation systems; and weld overlay.
