ASTM B366 C276 Hastelloy Nickel Alloy Buttweld Pipe Fitting Elbow B16.9
Alloy C-276 (UNS N10276, W. Nr. 2.4819) is known for its corrosion resistance in various corrosive media. High molybdenum content provides resistance to localized corrosion (such as pitting). Low carbon minimizes the precipitation of carbides during the welding process to maintain resistance to intergranular corrosion in the heat affected zone of the welded joint. It is used for chemical processing, pollution control, pulp and paper production, industrial and municipal waste treatment, and the recovery of "acidic" natural gas. Applications in air pollution control include stacked linings, pipelines, dampers, scrubbers, flue gas reheaters, fans, and fan casings. In chemical treatment, this alloy is used for components including heat exchangers, reaction vessels, evaporators, and conveying pipelines.
Hastelloy C-276 alloy has excellent chemical corrosion resistance, including strong oxidizing agents such as iron trichloride and copper chloride, thermal polluting media (organic and inorganic), chlorine, acid and acid, anhydride, seawater and brine solutions. It is used in flue gas desulfurization systems because it has excellent resistance to Liu compounds and chloride ions in most scrubbers. C-276 alloy has excellent resistance to pitting corrosion and stress corrosion cracking. It is also one of the few materials that can withstand the corrosive effects of wet LV gas, hypochlorite, and chlorine dioxide.

Corrosion resistance:
Hastelloy C-276 is a tungsten-containing nickel-chromium-molybdenum alloy with very low silicon carbon content and is considered to be a good corrosion resistant alloy. The alloy has the following characteristics: ① Excellent corrosion resistance to most corrosive media in the oxidation and reduction atmosphere. Excellent resistance to pitting corrosion, crevice corrosion and stress corrosion. The high content of molybdenum and chromium make the alloy resistant to chloride ion corrosion, and the tungsten element further improves the corrosion resistance. At the same time, C-276 alloy is one of the only several materials resistant to the corrosion of humid chlorine gas, hypochlorite and chlorine dioxide solutions, and has significant corrosion resistance to high concentrations of chloride salt solutions such as ferric chloride and copper chloride. Suitable for sulfuric acid solutions of various concentrations, it is one of the few materials that can be applied to hot concentrated sulfuric acid solutions.
