Butt Welded Fittings ASTM B366 Hastelloy C276, UNS N10276 Nickel Alloy 90Deg LR Elbow
Hastelloy C276 is a nickel-molybdenum-Chromium superalloy with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments. The high nickel and molybdenum contents make the nickel steel alloy especially resistant to pitting and crevice corrosion in reducing environments while chromium conveys resistance to oxidizing media. The low carbon content minimizes carbide precipitation during welding to maintain corrosion resistance in as-welded structures. This nickel alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process
application in an as welded condition. Although there are several variations of the Hastelloy nickel alloy, Hastelloy C-276 is by far the most widely used. Alloy C-276 is widely used in the most severe environments such as chemical processing, pollution control, pulp and paper production, industrial and municipal waste treatment, and recovery of sour natural gas.
In what forms is Hastelloy C276 Available at YUHONG HOLDING GROUP?
Corrosion Resistant Hastelloy C276
Considered one of the most versatile corrosion resistant alloys available, Hastelloy C-276 exhibits excellent resistance in a wide variety of chemical process environments including those with ferric and cupric chlorides, hot contaminated organic and inorganic media, chlorine, formic and acetic acids, acetic anhydride, seawater, brine and hypochlorite and chlorine dioxide solutions. In addition, alloy C-276 resists formation of grain boundary precipitates in the weld heat affected zone making it useful for most chemical processes in the as-welded condition. This alloy has excellent resistance to pitting and stress corrosion cracking.
What are the characteristics of Hastelloy C276?
Excellent corrosion resistance in reducing environments
Exceptional resistance to strong solutions of oxidizing salts, such as ferric and cupric chlorides

Fabrication with Hastelloy C-276
Hastelloy C-276 alloy can be forged, hot-upset and impact extruded. Although the alloy tends to work-harden, you can have it successfully spun, deep-drawn, press formed or punched. All of the common methods of welding can be used, although the oxyacetylene and submerged arc processes are not recommended when the fabricated item is for use in corrosion service. Hastelloy C-276 Welding Material Alloy C276 welding products are used as matching composition filler material for welding C276 alloy wrought and cast products, for dissimilar welding applications including other nickel-chromium-molybdenum alloys and stainless steels, and for weld overlay or cladding of steels.
