(UNS:N10002) A nickel-molybdenum-chromium alloy with tungsten added that results in excellent corrosion resistance in a wide range of severe environments including wet chlorine gas, hypochlorite, and chlorine dioxide solutions. The alloy is especially resistant to pitting and crevice corrosion and has good resistance to sulphuric, phosphoric, acetic, and nitric acids. Alloy C-276 is an improved version of alloy C in that it has vastly improved fabricability and resists the formation of grain-boundary carbide precipitates during welding. Alloy C-4 has outstanding high temperature stability, while for even better overall corrosion resistance, alloy C-22 excels in pitting resistance. |
