Monel is a group of nickel alloys, primarily composed of nickel (up to 67%) and copper, with small amounts of iron, manganese, carbon, and silicon. Stronger than pure nickel, Monel alloys are resistant to corrosion by many agents, including rapidly flowing seawater. They can be fabricated readily by hot- and cold-working, machining, and welding.

Monel was created by David H. Browne, chief metallurgist for International Nickel Co. Monel alloy 400 is binary alloy of the same proportions of nickel and copper as is found naturally in the nickel ore from the Sudbury (Ontario) mines and is therefore considered a puritan alloy. Monel was named after company president Ambrose Monell, and patented in 1906.One L was dropped, because family names were not allowed as trademarks at that time.The name is now a trademark of Special Metals Corporation.

Monel is an alloy (i.e. combination of two or more elements of which at least one is a metal, and where the resultant material has metallic properties). It is based on nickel (65-70%) and copper (20-29%) and also contains iron and manganese (5%) and other compounds. It is a very expensive alloy, with cost ranging from 5 to 10 times the cost of copper and nickel, hence its use is limited to those applications where it cannot be replaced with cheaper alternatives.

Middle East Suppliers supplies Monel 400, K-500. Most of these grades are available in the form of plate, sheet, pipe, tubing, fittings, bar, flanges, wire and rod.

 Monel 400

Monel 400 is a nickel-copper alloy (about 23% Cu–67% Ni ) that is resistant to sea water and steam at high temperatures as well as to salt and caustic solutions. Alloy 400 is a solid solution alloy that can only be hardened by cold working. This nickel alloy exhibits characteristics like good weldability, good corrosion resistance and high strength. A low corrosion rate in rapidly flowing brackish or seawater combined with excellent resistance to stress-corrosion cracking in most freshwaters, and its resistance to a variety of corrosive conditions led to its wide use in marine applications and other non-oxidizing chloride solutions. This nickel alloy is particularly resistant to hydrofluoric and hydrochloric acids when they are de-aerated. As would be expected from its high copper content, alloy 400 is rapidly attacked by nitric acid and ammonia systems white metals supplies monel 400 in the form of monel400 plate, monel400 sheet, monel400 strip, monel400 bar, monel400 wire, monel400 pipe, monel400 tubing, monel400 pipe fittings and monel400 flanges.

 

Monel 500

Monel K500 is a precipitation-hardenable nickel-copper alloy that combines the excellent corrosion resistance characteristic of Monel 400 with the added advantage of hardness and greater strength. These amplified properties, strength and hardness, are obtained by adding titanium and aluminum to the nickel-copper base and by a thermal processing used to effect precipitation, typically called age hardening or aging. When in the age-hardened condition, Monel K-500 has a greater tendency toward stress-corrosion cracking in some environments than Monel 400. Monel K-500 has approximately three times the yield strength and double the tensile strength when compared with Monel 400. Plus, it can be further strengthened by cold working prior to precipitation hardening. The strength of this nickel steel alloy is maintained to 1200° F but stays ductile and tough down to temperatures of 400° F. Its melting range is 2400-2460° F.

The corrosion resistance of monel K-500 is substantially equivalent to that of alloy 400 except that when in the age-hardened condition, nickel monel K-500 has a greater tendency toward stress-corrosion cracking in some environments. Monel K-500 has been found to be resistant to a sour-gas environment. The combination of very low corrosion rates in high-velocity sear water and high strength make monel K-500 particularly suitable for shafts of centrifugal pumps in marine service. In stagnant or slow-moving sea water, fouling may occur followed by pitting but this pitting slows down after a fairly rapid initial attack.

Middle East Suppliers supplies Monel K500 in the form of monel K500 plate, monel K500 sheet, monel K500 bar, monel K500 wire, monel K500 pipe, monel K500 tubing, monel K500 pipe fittings and monel K500 flanges.

Characteristics of Monel
  • Highly resistant to corrosion. Monel is well known as a corrosion strong, rust-resistant material. It is resistant to corrosion and acids, and some alloys can withstand a fire in pure oxygen.
  • Stronger than steel
  • Malleable
  • Low coefficient of thermal expansion
  • Highly resistant to alkalis
  • It can be welded, brazed and soldered

 

In what Applications are Monel alloys used?
  • Pump shafts,
  • oil-well tools, instruments,
  • doctor blades and scrapers
  • springs, valve trim, fasteners, marine propeller shafts
  • Marine components
  • Chemical and hydrocarbon processing equipment
  • Valves, pumps, shafts, fittings, heat exchangers
