Quick Detail

Inconel® C-276 or Hastelloy® C-276 and is an improved wrought version of alloy C in that it usually doesn't need to be solution heat-treated after welding and has vastly improved fabricability. This alloy is resistant to the formation of grain boundary precipitates, specifically in the weld-heat affected zone. This attribute makes Alloy C-276 suitable for use in the as-welded condition.

Alloy C-276 has excellent resistance to both localized corrosion and oxidizing or reducing media. Because of its versatility, alloy C-276 can be used where corrosive conditions are likely to occur or in multipurpose plants. Alloy C-276's native corrosion resistant properties extend to a wide variety of chemical process environments, including strong oxidizers such as ferric and cupric chlorides, hot contaminated media (organic and inorganic), chlorine, formic and acetic acids, acetic anhydride, and seawater and brine solutions. It is used in flue gas desulfurization systems because of its excellent resistance to sulfur compounds and chloride ions encountered in most scrubbers. Alloy C-276 has excellent resistance to pitting, stress-corrosion cracking, and oxidizing atmospheres up to 1900 °F (1038 °C). It is also one of the few materials that withstands the corrosive effects of wet chlorine gas, hypochlorite and chlorine dioxide.

Uses and Applications

Some typical applications 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.

Alloy C-276 sheet 0.044" thick in the heat-treated condition at 2050 °F, rapid quenched, has an average olsen cup depth of 0.48". 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.

Digesters and bleach plants in the paper industry.

Components exposed to sour gas.

Equipment for flue-gas desulphurisation plants.

Evaporators, heat exchangers, filters and mixers used in sulphuric acid environments.

Sulphuric acid reactors.

Organic chloride process equipment.

Equipment for processes utilising halide or acid catalysts.
