Nickel matrix, can resistant corrosion in some medium, called the nickel-based corrosion resistant alloy.
The main alloying elements of nickel-based alloys are copper、 chromium and molybdenum. It has a good overall performance, resistance to various acid corrosion and stress corrosion. The first application (1905 US production) is a nickel-copper (Ni-Cu) alloy, also known as Monel (Monel alloy Ni70Cu30). There are also nickel-chromium (Ni-Cr) alloys (nickel-based heat-resistant alloy), nickel-molybdenum (Ni-Mo) alloys (mainly refers Hastelloy B series), nickel chromium-molybdenum (Ni-Cr-Mo) alloys (mainly refers Hastelloy C series) and the like. At the same time, pure nickel is a typical representative of nickel based corrosion resistant alloys. These nickel-based corrosion resistant alloy is mainly used in the manufacture of petroleum, chemical, power and other corrosion-resistant components of the environment.
