59Ni-23cr-16mo-1.6cu-0.08si-0.01c is the most comprehensive corrosion-resistant alloy with excellent uniform corrosion resistance in both oxidation and reduction environments. Compared with C-276 alloy, it has excellent stress corrosion cracking resistance and better local corrosion resistance.
Hastelloy C-2000 is a patented product of Haines Company 1995.
Nickel-chromium-molybdenum alloy is a medium with high resistance to chromium oxidation and molybdenum-tungsten reduction. However, due to the limitation of metallurgy, it is impossible to improve the oxidation resistance and reduction resistance by increasing the contents of Cr, Mo and W.
Hastelloy C-2000 is designed to solve this problem. The biggest difference between Hastelloy C-2000 and other Ni-Cr-Mo alloys lies in the innovative addition of 1.6% Cu, which greatly improves the corrosion resistance of the alloy in reducing medium. However, the addition of copper leads to the decrease of local corrosion resistance and the thermal stability is not as good as that of 59 alloy. The corrosion resistance of this alloy is better than that of C-276, and its forming, welding and machining characteristics are similar to those of C-276.

The development of Hastelloy C-2000 expands the application range of single alloy. Hastelloy C-2000 is an alloy that can resist a series of corrosive chemicals (including sulfuric acid, hydrochloric acid and hydrofluoric acid) by adding copper to Ni-Cr-Mo system. The combination of molybdenum and copper provides excellent corrosion resistance for the reducing medium, and the high chromium content makes it have good oxidation resistance.
