Alloy C2000 this alloy is designed to resist more corrosive chemicals, including sulfuric acid, hydrochloric acid, chlorofluoroic acid. Different from the previous optimized NI-CR-MO alloy, which can only resist oxidizing or reducing acids, C-2000 alloy has corrosion resistance in both environments. The combined action of molybdenum and copper (at 16% and 1.6% respectively) makes the alloy have excellent corrosion resistance in reducing medium, and the high chromium content (23% wt) ensures the corrosion resistance in oxidizing medium.
