Hastelloy C22 /UNS N06022/ 2.4602 Material Summary

Nickel Alloy C22 pipe is a fully austenitic nickel-based superalloy that's cost-effective for clients seeking ease of forming combined with superior corrosion resistance. Also known as Inconel 22 and Hastelloy C22, this material is highly ductile, making cold forming easier. Inconel 22 features resistance to an array of attacks from corrosion, pitting, crevice corrosion, intergranular, and stress corrosion cracking. Both cost effective and versatile; Inconel 22 is used by a wide variety of industries.

Nickel Alloy C-22 is a versatile Ni-Cr-Mo-W alloy with better comprehensive corrosion resistance performance than other Ni-Cr-Mo alloys, including Alloy C-276, Alloy C-4 and Alloy 625. Alloy 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. It also offers optimum resistance to environments where reducing and oxidizing conditions are encountered in process streams.
