C276
Overview
HASTELLOY C276 is a Nickel-chromium-molybdenum wrought alloy that is considered the most versatile corrosion resistant alloy available. This alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in an as welded condition. Alloy C-276 also has excellent resistance to pitting, stress-corrosion cracking and oxidizing atmospheres up to 1900°F. Alloy C-276 has exceptional resistance to a wide variety of chemical environments.
Characteristics
- HASTELLOY C276 is one of the few alloys resistant to wet chloride gas, hypochlorite and chlorine dioxide solutions.
- HASTELLOY C276 has exceptional resistance to strong solutions of oxidizing salts, such as ferric and cupric chlorides.
- HASTELLOY C276 is not prone to grain boundary precipitation in the as welded condition and therefore suitable for many chemical process applications
Applications
- Digesters and bleach plants in the paper industry.
- Components exposed to sour gas.
- Equipment for flue-gas desulfurisation 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.
Some typical applications of HASTELLOY C276 include equipment components in chemical and petrochemical organic chloride processes and processes utilizing halide or acid catalysts. Other industry applications are pulp and paper (digesters and bleach areas), scrubbers and ducting for flue gas desulfurization, pharmaceutical and food processing equipment.
HASTELLOY C-276 is a nickel-chromium-molybdenum alloy with universal corrosion resistance unmatched by any other alloy. It has outstanding resistance to a wide variety of chemical process environments including 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, sea water and brine solutions and hypochlorite and chlorine dioxide solutions. Alloy C276 also resists formation of grain boundary precipitates in the weld heat affected zone making it useful for most chemical processes in the as-welded condition. It has excellent resistance to pitting and stress corrosion cracking.
HASTELLOY C276 sheet 0.044" thick in the heat-treated condition at 2050°F, rapid quenched, has an average olsen cup depth of 0.48". Alloy C-276 can be successfully fabricated by many methods. The alloy tends to work harden but with the proper care, the alloy is readily hot and cold formed. Complete information on welding, machining and forming is available
