Differences between Monel and Hastelloy:
Monel and Hastelloy are two different types of nickel-copper alloys. Monel is more corrosion resistant, but it is less heat-conductive. It also has a lower melting point. This makes it perfect for high-temperature uses such as stove tops and gas pipes. But if you want a material with a higher melting point, you would be better off choosing Hastelloy because it can withstand very high temperatures without losing any strength or corrosion resistance. Monel is a nickel-copper alloy that resists corrosion in acidic environments. It can be used in piping, valves, and other fluid transfer components.
Monel parts are also good for use in high-temperature applications. Hastelloy is an alloy of nickel, chromium, and molybdenum. It provides the right mix of both tensile strength and corrosion resistance for most industrial applications. Monel is a family of iron-nickel alloys containing nickel and copper, called cupronickel. Monel metal is nonmagnetic and resistant to corrosion in seawater. Hastelloy is a family of nickel-based superalloys, with a percentage of cobalt, titanium, iron, and molybdenum making up the composition. Hastelloy has a much higher nickel content than Monel. Monel is a nickel-copper alloy, and Hastelloy is a series of alloys containing nickel and several other metals. Monel has a low voltage coefficient and is resistant to most corrosive environments. Whereas Hastelloy is designed for applications in high-temperature, oxidizing environments.
