Hastelloy C-276 has excellent resistance to localized corrosion, stress corrosion cracking, and to both oxidizing and reducing media, thus making it suitable for a wide variety of chemical process environments, including ferric and cupric chlorides, hot contaminated media (organic and inorganic), formic and acetic acids, seawater and brine solutions. It is one of the few materials that withstands the corrosive effects of wet chlorine gas, hypochlorite and chlorine dioxide.

3. Physical properties

Characters:

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.

Application:

Pollution control stack liners, ducts, dampers, scrubbers, stack-gas reheaters, fans and fan housings.

Flue gas desulfurization systems.

Chemical processing components like heat exchangers,  reaction vessels, evaporators, and transfer piping.

Sour gas wells.

Pulp and paper production.

Waste treatment.

Pharmaceutical and food processing equipment.
