Monel 400 Round Bar By Mafatlal Rajeshkumar & Co

MONEL nickel alloy is a solid solution alloy that can be hardened by the process of cold working.

MONEL is a trademark of Special Metals Corporation under which a series of nickel-copper alloys are grouped. Commercially there are many types of MONEL available, such as alloy 400, alloy 401, alloy R-405, Alloy K-500 and Monel 404.

The Monel 400 alloy is also known as super alloy monel. This alloy is available in some standard shapes such as hexagon, round, tube, pipe, plate, strip, sheet and wire.

The proportions of copper and nickel used to make monel are the same as that found in the nickel ore found in Ontario mines. This alloy exhibits good corrosion resistance. This datasheet will look into the chemical composition, properties and applications of MONEL 400 alloy.

The MONEL 400 alloy is used in the following applications:-

Marine fixtures, pumps, valves and piping systems for sea water applications
Chemical plant equipment
Frames for eyeglasses
Aerospace applications
Musical instruments.

Machinability
The machinability of MONEL 400 is difficult as it work-hardens during machining. The conventional machining techniques used on iron alloys may be used for this alloy.

Welding
Welding methods including gas-arc welding, metal-arc welding, gas-metal-arc welding and submerged-arc welding are recommended on this alloy.

Forging
Forging of this alloy is to be done by controlled procedures.

Hot working
Hot working on this alloy needs to be done by choosing proper temperatures. Typical temperatures for hot working range between 648-1176A C (1200-2150A F).

Cold working
Cold working may be done using soft die materials for better finishing.

Annealing
MONEL 400 alloy may be annealed at 926A C (1700A F).
