A high performace nickel alloy for severe corrosion environments
Hastelloy C2000 flanges combine the outstanding resistance to oxidizing media of C276 with superior resistance to non-oxidizing environments, making it a unique alloy for protecting chemical process equipment across a wide range of conditions including streams contaminated with ferric ions. It was designed to offer greater versatility compared to the other Hastelloy alloys. This was accomplished by increasing the chromium and molybdenum content in addition to adding a small, but effective addition of copper (1.6%). The addition of copper provides C2000 flanges enhanced temperature capability in sulfuric acid, hydrofluoric acid, and dilute hydrochloric acid.

- Excellent resistance to all acids (especially hydrochloric, sulfuric, and hydrofluoric) over large temperature ranges
- Excellent protection from chlorides and other halide solutions, specifically pitting, crevice attack, and stress corrosion cracking
- Excellent resistance to stress corrosion cracking and superior resistance to localized corrosion compared to C-276
- Chemical process industry reactors, heat exchangers, columns, and piping
- Pharmaceutical industry reactors and dryers
- Flue gas desulfurization systems
C2000 alloy, UNS N06200, is a corrosion resistant nickel alloy with excellent resistance to uniform corrosion in oxidizing or re-ducing environments. Due to the addition of copper and the high content of chromium, it has enhanced corrosion resistance to sulfuric acid and process streams contaminated with ferric ions. In addition it has excellent resistance to stress corrosion cracking and superior resistance to localized corrosion as compared to C-276 alloy. This alloy has limited availability and can be made into sizes only 1/2" and greater is size for fasteners.
