Hastelloy C22 alloy, UNS N06022, has better overall corrosion resistance in oxidizing corrosives than C-276 and Inconel 625 alloys due to the higher chromium content. More specifically, C22 fasteners provides better protection when used in certain saturated wet chlorine environments. In addition, its high chromium content provides C22 fasteners much better resistance to oxidizing media that C276. This provides it exceptional resistance to chloride-induced pitting although, in most cases because of its availability, C-276 fasteners are a more cost-effective option. Hastelloy C22 fasteners also offer outstanding resistance to pitting and crevice corrosion, as well as stress corrosion cracking. Use of C22 fasteners should be limited to temperatures below 1250° F. This alloy has limited availability and can be made into fastener in larger diameters only (1/2" and greater in size).
