Metal Roll Monel is metal roll made of Monel, it is kind of Nickel-Copper alloy metal, which is resistant to sea water and steam at high temperatures as well as to salt and caustic solutions.
Description:
Alloy 400 is a nickel-copper alloy with excellent corrosion resistance in a wide variety of media. The alloy is characterized by good general corrosion resistance, good weld ability and moderate to high strength. The alloy has been used in a variety of applications. It has excellent resistance to rapidly flowing brackish water or seawater. It is particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated. The alloy is slightly magnetic at room temperature. The alloy is widely used in the chemical, oil and marine industries.
Monel 400 alloy in the fluoride gas, hydrochloric acid, sulfuric acid, hydrofluoric acid and their derivatives have a very good corrosion resistance property, and possess better corrosion resistance more than the copper alloy in the sea water.
Acid medium: Monel 400 have corrosion resistance in less than 85% consistency of sulfuric acid.
Monel 400 is an important material that resistant to hydrofluoric acid. Water corrosion: Monel 400 alloy in most corrosion cases of water, not only excellent corrosion resistance, but also less pitting, stress corrosion, the corrosion rate less than 0.025mm / a.
High temperature corrosion: Monel 400 for the work of the highest temperature at about 600 °C in general in the air, in the high temperature steam, the corrosion rate less than 0.026mm / a.
Ammonia: Monel 400 can be resistant to an hydrous ammonia and aminate conditions corrosion below 585 °C due to the high nickel.
Applications:
Feed water and steam generator tubing.
Brine heaters, sea water scrubbers in tanker inert gas systems.
Sulfuric acid and hydrofluoric acid alkylation plants.
Pickling bat heating coils.
Heat exchangers in a variety of industries.
Transfer piping from oil refinery crude columns.
Plant for the refining of uranium and isotope separation in the production of nuclear fuel.
Pumps and valves used in the manufacture of perchlorethylene, chlorinated plastics.

Competitive Advantage:
Corrosion resistance in an extensive range of marine and chemical environments. From pure water to no oxidizing mineral acids, salts and alkalis. This alloy is more resistant to nickel under reducing conditions and more resistant than copper under oxidizing conditions, it does show however better resistance to reducing media than oxidizing. Good mechanical properties from subzero temperatures up to about 480C. Good resistance to sulfuric and hydrofluoric acids. Aeration however will result in increased corrosion rates. May be used to handle hydrochloric acid, but the presence of oxidizing salts will greatly accelerate corrosive attack. Resistance to neutral, alkaline and acid salts is shown, but poor resistance is found with oxidizing acid salts such as ferric chloride. Excellent resistance to chloride ion stress corrosion cracking.
