Cold Roll Strip Hastelloy C276 Corrosion Resistant Alloy
Hastelloy C276 alloy is one of the most well known corrosion resistant alloys, and that was appeared 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.
Like other nickel alloys, it is ductile, easy to form and weld, and possesses exceptional resistance to stress corrosion cracking in chloride-bearing solutions (a form of degradation to which the austenitic stainless steels are prone). With its high chromium and molybdenum contents, it is able to withstand both oxidizing and non-oxidizing acids, and exhibits outstanding resistance to pitting and crevice attack in the presence of chlorides and other halides. Furthermore, it is very resistant to sulfide stress cracking and stress corrosion cracking in sour, oilfield environments.
Chemical composition is (%)
Advantages 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
Applications of Hastelloy C276
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
Pharmaceutical and food processing equipment
