Hastelloy Fastener Overview

Hastelloy fasteners are ideally suited for a wide variety of medium to severe corrosive acid environments.  The most common grade for Hastelloy fasteners is Hastelloy C276 (2.4819), which is the one of the most versatile of the corrosion resistant nickel alloys – exceeding that of Inconel or Monel. Hastelloy fasteners are also available in other specialty grades that can address more niche corrosion issues. Hastelloy is often used for applications involving:

HASTELLOY B2 (2.4617)Hastelloy B3 alloy, UNS N10665, offers excellent resistance to hydrochloric acid in all temperatures and concentrations, yet has poor corrosion resistance to oxidizing chemicals and in the presence of ferric or cupric salts. In addition, Hastelloy B2 has excellent resistance to pitting, stress corrosion cracking, and to knife-line and heat-affected zone attack. However B2 has little chromium, and it should NOT be used with oxidizing media in the presence of salts.  Like other Hastelloy alloys, B2 fasteners can be used in the as-welded condition because they resist the formation of grain-boundary carbide precipitates in the weld heat-affected zone. It is recommended that B2 fasteners not be utilized between 1000° F and 1600° F because of a reduction in the ductility.

HASTELLOY C22 (2.4602)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).
