Monel Wire

Monel wire Include two kinds: Monel 400 Wire and Monel K500 Wire

1: Monel 400 Wire:

Monel 400 Wire is corrosion resisting, such as resistant to sea water and steam at high temperatures, resistant to salt and caustic solutions. Meanwhile, it exhibits characteristic like high strength. Monel 400 Wire has low corrosion rate in flowing brackish or seawater while performing excellent resistance to stress-corrosion cracking in most freshwaters. This Wire's good resistance to a variety of corrosive conditions contributes to the wide application in marine and other non-oxidizing chloride solutions.

Monel 400 Wire is particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated. However, its high copper content, make alloy 400 can be rapidly attacked by nitric acid and ammonia systems.Monel 400 Wire also has good Adaptability to wide range of application temperature. It maintains good mechanical properties at subzero temperatures, as well as in temperatures up to 1000° F, The melting point is 2370-2460° F.

Monel 400 Wire is immune to chloride ion stress corrosion cracking in typical environments. Besides, it is good corrosion resistant in reducing environments, but poor in oxidizing conditions. It is not useful in oxidizing acids, such as nitric acid and nitrous. Monel 400 Wire would be attacked in sulfur-bearing gases above approximately 700° F and molten sulfur attacks the alloy at temperatures over approximately 500° F. However, it is resistant to most alkalis, salts, waters, food products, organic substances and atmospheric conditions at normal and elevated temperatures.

Monel 400 Wire offers about the same corrosion resistance as nickel but with higher maximum working pressures and temperatures and at a lower cost due to its superior ability to be machined.

2: Monel K-500 Wire

Monel K500 Wire is one kind of the nickel-copper alloy Wire. Monel K500 Wire combines the excellent corrosion resistance of Monel 400 Wire with the added advantage of greater strength and hardness. Alloy K-500 Wire has approximately three times the yield strength and double the tensile strength when compared with alloy 400. When in the age-hardened condition.

Monel K-500 Wire has a greater tendency toward stress-corrosion cracking in some conditions than Monel 400 alloy Wire. The strength of this nickel Copper alloy is maintained to 1200° F but stays ductile and tough down to temperatures of 400° F. Its melting range is 2400-2460° F. Nickel alloy K-500 Wire has a greater tendency toward stress-corrosion cracking in some environments.

Monel K-500 Wire is resistant to a sour-gas environment. The combined Characteristics of very low corrosion rates in high-velocity sear water and high strength make alloy K-500 Wire particularly suitable for 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.

This nickel alloy is spark resistant and non-magnetic to -200° F. However, it is possible to develop a magnetic layer on the surface of the material during processing. Aluminum and copper may be selectively oxidized during heating, leaving a magnetic nickel rich film on the outside. Pickling or bright dipping in acid can remove this magnetic film and restore the non-magnetic properties.
