Description

Hastelloy® C-2000 alloy broadens the range of the nickel-chromium-molybdenum alloy family with the addition of copper which allows for resistance to an extensive range of corrosive chemicals including sulfuric, hydrochloric, and hydrofluoric acids over large temperature ranges. Molybdenum and copper provide excellent corrosion resistance to reducing media while the chromium content gives good oxidizing resistance.
