Short Description:

MONEL nickel-copper alloy 400 (UNS N04400) 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.

Characteristics of Monel 400

● Resistant to seawater and steam at high temperatures

● Excellent resistance to rapidly flowing brackish water or seawater

● Excellent resistance to stress corrosion cracking in most freshwaters

● Particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated

● Offers some resistance to hydrochloric and sulfuric acids at modest temperatures and concentrations, but is seldom the material of choice for these acids

● Excellent resistance to neutral and alkaline salt

● Resistance to chloride induced stress corrosion cracking

● Good mechanical properties from sub-zero temperatures up to 1020° F

● High resistance to alkalis

      Monel k-500 UNS N05500/ W.Nr. 2.4375

      MONEL alloy K-500 (UNS N05500) is a nickel-copper alloy which combines the excellent corrosion resistance of MONEL alloy 400 with the added advantages of greater strength and hardness. The increased properties are obtained by adding aluminum and titanium to the nickel-copper base, and by heating under controlled conditions so that submicroscopic particles of Ni3 (Ti, Al) are precipitated throughout the matrix. The thermal processing used to effect precipitation is commonly called age hardening or aging.
