Product Description
Hastelloy C276 Nickel Alloy Welded Super Duplex Round Bars
Hastelloy C-276 alloy is a nickel-chromium-molybdenum alloy containing tungsten. Because of its extremely low silicon-carbon content, it is considered a universal anti-corrosion alloy. It is mainly resistant to wet chlorine, various oxidizing chlorides, chloride salt solutions, sulfuric acid and oxidizing salts, and has good corrosion resistance in low temperature and medium temperature hydrochloric acid. Therefore, in the past 30 years, in harsh corrosive environments, such as chemical industry, petrochemical industry, flue gas desulfurization, pulp and paper, environmental protection and other industrial fields, it has been widely used.
The solution heat treatment of Hastelloy C-276 alloy material includes two processes: (1) heating at 1040°C~1150°C; (2) quickly cooling to a black state (about 400°C) within two minutes, and the processed material Has good corrosion resistance. Therefore, it is not effective to perform stress relief heat treatment on Hastelloy C-276 alloy only. Before heat treatment, it is necessary to clean up all the dirt on the alloy surface, such as oil stains, that may produce carbon elements during the heat treatment process.
The surface of Hastelloy C-276 alloy will produce oxides during welding or heat treatment, which will reduce the Cr content in the alloy and affect the corrosion resistance, so the surface must be cleaned. You can use a stainless steel wire brush or a grinding wheel, and then immerse it in a mixture of nitric acid and hydrofluoric acid in an appropriate proportion for pickling, and finally rinse it off with clean water.
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.
Characteristics
  • Excellent corrosion resistance in reducing environments
  • Exceptional resistance to strong solutions of oxidizing salts, such as ferric and cupric chlorides
  • High nickel and molybdenum contents providing good corrosion resistance in reducing environments
  • Low carbon content which minimizes grain-boundary carbide precipitation during welding to maintain resistance to corrosion in heat-affected zones of welded joints
  • Resistance to localized corrosion such as pitting and stress-corrosion cracking
  • One of few materials to withstand the corrosive effects of wet chlorine gas, hypochlorite and chlorine dioxide

  • Waste treatment
  • Pharmaceutical and food processing equipment
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.
