Corrosion resistance and main use environment:

The alloy c-276 is a tungsten ni-chrome-molybdenum alloy with very low silicon carbon content and is considered to be a universal anti-corrosion alloy. The alloy has the following characteristics: it has excellent corrosion resistance to most corrosive media in the state of oxidation and reduction. Excellent corrosion resistance, crevice corrosion and stress corrosion. High molybdenum and chromium content enable the alloy to be resistant to chloride ion corrosion and tungsten elements further improve the corrosion resistance. At the same time, the C - 276 alloy is one of the several kinds of wet chlorine, hypochlorite and chlorine dioxide solution corrosion resistant materials, one of the high concentration of chlorate solution such as ferric chloride and copper chloride corrosion resistance significantly. It is suitable for various concentrations of sulfuric acid solution. It is one of the few materials that can be used in the solution of concentrated sulfuric acid.
