Hastelloy C2000 is a new type of Ni-Cr-Mo alloy. Based on C4 alloy, the content of chromium is improved, and the addition of copper greatly improves the oxidation resistance and the corrosion ability of reducing medium of the alloy. Hastelloy C2000 is currently a series of alloys with good corrosion resistance of H2SO4, but the intercrystalline corrosion resistance is not as good as C4 alloy

Corrosion resistance including sulfuric acid hydrochloric hydrofluoric acid phosphate organic chlorine alkali metal crevice corrosion pitting,stress corrosion cracking.
C-2000 alloy shows better resistance to pitting and crevice corrosion than C-276 alloy the industrial standard.
Welding and machining formability of Hastelloy C-2000 which are similar to C276,solve the dilemma on the alloy design.
Excellent corrosion resistance to reduction environment without sacrificing stability of metallurgy in combination with high chromium and contents of molybdenum and copper.
