Table Of content
Hastelloy C276 Instrumentation fittings are made of a wrought nickel-chromium-molybdenum alloy that is widely considered to be the most corrosion-resistant alloy on the market. Hastelloy C276 is suitable for most chemical process applications in the as-welded state because it resists the formation of grain boundary precipitates in the weld heat-affected zone. Pitting, stress-corrosion cracking, and oxidizing atmospheres up to 1900°F are all resistant to Hastelloy C276 Instrumentation fittings. Instrumentation fittings made of Hastelloy C-276 can tolerate a wide range of chemical conditions.
Hastelloy C-276 Instrumentation fittings are a nickel-chromium-molybdenum alloy with unrivaled corrosion resistance across the board. Ferric and cupric chlorides, hot contaminated mineral acids, solvents, chlorine and chlorine contaminated (both organic and inorganic), dry chlorine, formic and acetic acids, acetic anhydride, seawater, and brine solutions, and hypochlorite and chlorine dioxide solutions are all particularly resistant to it. Alloy C276 resists the formation of grain boundary precipitates in the weld heat-affected zone in the as-welded condition, making it appropriate for most chemical applications. It is resistant to pitting and stress corrosion cracking.
Hastelloy C276 Instrumentation fittings are used in various applications like Digesters and bleach plants in the paper industry, Components exposed to sour gas, Equipment for flue-gas desulfurization plants, Evaporators, heat exchangers, filters and mixers used in sulfuric acid environments, Sulfuric acid reactors, Organic chloride process equipment, Equipment for processes utilizing halide or acid catalysts.
