High Performance Alloys stocks and
produces Monel 400 in this grade in the following forms: Bar, wire, sheet, plate, coil, fasteners and forgings.
Monel 400 is a Nickel-Copper alloy, resistant to sea water and steam at high temperatures as well as to salt and caustic solutions.
Monel 400 is a nickel-copper alloy with excellent corrosion resistance in a wide variety of media.
Monel 400 is characterized by good general corrosion resistance, good weldability and moderate to high strength.
The alloy has been used in a variety of applications. It has excellent resistance to rapidly flowing brackish water or seawater.
It is particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated. The alloy is slightly magnetic at room temperature.
Monel 400 is widely used in the chemical, oil and marine industries.
