Description
Common Trade Names: Monel 400, Alloy 400; Nickel 400; Nickelvac 400; Nicorros 400.
Monel® Alloy nickel-copper alloy 400 (UNS N04400; W.Nr. 2.4360 and 2.4361) is a solid-solution alloy that can be hardened only by cold working. It has high strength and toughness over a wide temperature range and excellent resistance to many corrosive environments.
Alloy 400 is widely used in many fields, especially marine and chemical processing. Typical applications are valves and pumps; pump and propeller shafts; marine fixtures and fasteners; electrical and electronic components; springs; chemical processing equipment; gasoline and fresh water tanks; crude petroleum stills, process vessels and piping; boiler feed water heaters and other heat exchangers; and deaerating heaters.
Available Product Forms:
Pipe, tube, sheet, strip, plate, round bar, flat bar, forging stock, hexagon, wire
