Nickel alloy has excellent corrosion resistance and heat resistance, can adapt to a variety of harsh corrosive environment. Nickel itself is a kind of multi-function corrosion resistant material, strength, high hardness, good ductility and malleability, good compatibility, and other metal elements is a kind of ideal of alloying elements, in the chemical, alkali, oil, metallurgical and other industries are widely used, the corrosion resistance of nickel and nickel alloy, to further improve the corrosion resistance of nickel base alloy is critical.
