Hastelloy C-276 is a wrought corrosion-resistant alloy. A prime advantage of this alloy is that it generally does not require solution heat treatment after welding. It resists the formation of grain boundary precipitates that would degrade corrosion resistance.
Hastelloy Couplings is well known for Good machinability, although the alloy work hardens as is true of the nickel base alloys in general.Can be cold worked by all conventional methods.Weldable by all common methods except that excessive heat input should be avoided. Can be used in the “as-welded” condition without further heat treatment for most corrosive applications.The alloy can be forged or hot-upset by conventional means.Can be hot formed or extruded. Should be solution heat treated following hot forming.
Some of the area of present or potential use for alloy Hastelloy C276 are: Acetic acid/Acetic Anhydride, cellophane manufacturing, chlorine spargers, chlorination systems, circuit board etching equipment, complex acid/chemical mixtures, fans and blowers, galvanizing line equipment, gas scrubber systems, geothermal wells, HF furnaces, incineration systems, nuclear fuel reprocessing, pesticide production, phosphoric acid applications, pickling system components, plate heat exchangers, selective leaching systems, sulfur oxide cooling towers, sulfonation systems, and tubular heat exchangers
Like other nickel alloys, it is ductile, easy to form and weld, and possesses exceptional resistance to stress corrosion cracking in chloride-bearing solutions (a form of degradation to which the austenitic stainless steels are prone). With its high chromium and molybdenum contents, it is able to withstand both oxidizing and non-oxidizing acids, and exhibits outstanding resistance to pitting and crevice attack in the presence of chlorides and other halides. Furthermore, it is very resistant to sulfide stress cracking and stress corrosion cracking in sour, oilfield environments
