Nickel Base Castings and Nickel Alloy Castings

Nickel Base castings are used principally for their heat and corrosion resistance. The more common nickel base materials include Monel, Inconel, and the family of Hastelloy grades. Monel also includes a significant amount of copper, whereas Inconel is a Nickel-Chromium-Molybdenum alloy.

Monel Castings, Inconel Castings, and Hastelloy Castings are all examples of nickel alloy castings that are typically reserved for extreme conditions where their properties cannot be otherwise replicated due to their increased costs compared to stainless steels. Inconel alloys, for example, are oxidation and corrosion-resistant and are well suited for service in extreme environments subjected to high pressure and kinetic energy. Inconel Castings retain their strength over a wide temperature range, which makes them attractive for high-temperature applications where aluminum and steel would succumb to creep as a result of thermally induced crystal vacancies.

Similarly, Monel Castings’ high corrosion resistance makes them particularly well suited for applications requiring nickel base castings such as piping systems, seawater valves, and straining equipment. Certain monel alloys are completely non-magnetic and are used for anchor cable aboard minesweepers and as housings for magnetic-field measurement equipment. In recreational boating, Monel wire is used to seize shackles for anchor ropes as well as for water and fuel tanks, and for other underwater applications. Monel Castings are also used in propeller and impeller applications.
