Alloy C-276 is a wrought nickel-chromium-molybdenum-tungsten alloy which displays a remarkable corrosion resistance in a very wide range of processing environments. It displays excellent resistance to pitting and crevice corrosion, stress corrosion cracking and oxidising atmospheres up to 1040°C.
The high molybdenum content of C-276 provides the alloy with its excellent resistance to pitting and crevice corrosion. Since the alloy's low carbon content means C-276 is resistant to the formation of grain boundary precipitates in the heat-affected zone, C-276 can maintain its unique corrosion resistance in the as-welded condition.
Alloy C-276 is selected for resistance to wet chlorine gas, hypo-chlorites and many other aggressive chemicals. It also offers exceptional resistance to strong solutions of oxidising salts such as ferric and cupric chlorides.
