Hastelloy C276 Corrosion Resistant Nickel-based Alloy

Hastelloy C276 alloy is one of the most well known corrosion resistant alloys, and that was introduced in 1965,after 1970 using off-furnace refining (AOD,VOD) production to obtain ultra-low carbon and high purity. In order to reduce the disadvantages of consolidation heat treatment after welding or thermoforming, except for reducing carbon content, also the silicon content in the alloy reducing to 0.08%. Reducing the carbon content can reduce the amount of the carbon out quantity in the alloys, reducing the silicon content could reduce the amount of precipitation between metals in alloys, so that can achieve the purpose of increasing intercorrosion resistance of alloy. At the same time, the plasticity, toughness and processing properties of the alloy were improved.

Characters of the 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

Applications of Alloy 276

• 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
