Lanco Pipes & Fittings Co. is one of the leading exporter and supplier of Monel.Most of the companies which is belongs to marine, oil, and chemical processing industries use a great deal of Monel in their machinery products. Monel is a nickel alloy, prized for its strength and ability to resist corrosion. Its applications include crude gasoline, petroleum stills and marine fixtures, fresh water tanks, fasteners, and chemical processing equipment. At All Metals & Forge, clients can order Monel in several forms, including Monel 400 and Monel K500.

As resistant to corrosive forces as nickel but less expensive and easier to work with, Monel is widely used in situations where seawater, petroleum, or de-aerated acids come into contact with machinery. When a piece of equipment needs to stand up to exterior or interior corrosives, Monel is the fail-safe solution. It also has higher maximum working temperatures than nickel, making it the preferred metal for boiler feed water heaters and other heat exchangers. Regent Steel supplies Monel 400 and Monel k500 in the form of plate, sheet, strip, bar, wire, pipe, tubing, pipe fittings and flanges.

 

Monel 400

Monel 400 ® , Nickelvac ® 400, Nicorros® 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.

Monel 400® is a nickel-copper alloy that is hardened by cold working only. Monel 400® has low corrosion rate in flowing seawater, therefore it is widely used in marine applications. Monel 400® also has excellent resistance to stress corrosion cracking in most freshwaters. Monel 400® can be used in temperatures up to 1000 º F. The alloy has great mechanical properties at subzero temperatures.

Monel 500

Monel K500 ® UNS N05500

 

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.

Monel K-500® is a nickel-copper alloy with the same corrosion resistance and characteristics as the Monel 400®. The Monel K-500® has a greater strength and hardness then the 400, as a result of added aluminum and titanium. In age-hardened condition, it has greater tendency toward stress- corrosion cracking in some environments.
