What are the characteristics of Hastelloy C276?

• 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

In what applications is Hastelloy C-276 used?

• 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
