Alloy C-22 is nickel-chromium-molybdenum-tungsten alloy with improved resistance to both uniform and localized corrosion as well to a wide variety of mixed industrial chemicals. Alloy C-22 alloy exhibits superior weldability and alloy C-22 weld fillers are used to join other corrosion resistant alloys such as Alloy C-276 and AL-6XN® alloy.
