This alloy was developed to broaden the application range of one alloy. With the addition of Copper to the Nickel-Chromium-Molybdenum system, Hastelloy C-2000 is resistant to an extensive range of corrosive chemicals, including sulphuric, hydrochloric and hydrofluoric acids. The combination of Molybdenum and Copper provide excellent corrosion resistance to reducing media, while the high Chromium content gives good oxidising resistance.
