Monel alloy wire mesh is also known as monel wire mesh, monel screen, monel filter mesh, monel square hole mesh, monel crimped mesh, and monel woven mesh.
Monel, also known as copper-nickel alloy, is a kind of alloy with nickel as the base and copper, iron, manganese, etc.
Monel alloy is an alloy made of other elements. Monel alloy has good corrosion resistance, is silvery white, and is suitable for edge wire material.
The main products are: MONEL alloy 400; MONEL alloy 401; MONEL alloy 404; MONEL alloy R-405; MONEL alloy K-500;
Monel 400 alloy (UNSN04400 or MCu-28-1.5-1.8 or Ni68Cu28Fe) for monel wire mesh demister is a nickel-based alloy material with good corrosion resistance in seawater, chemical solvents, ammonia, sulfur, chlorine, chloride ions, various acidic media such as organic acids, alkaline media, salts and molten salts.
Monel 400 wire mesh: The structure of Monel 400 alloy is a high-strength single-phase solid solution. It is a corrosion-resistant alloy with the largest dosage, the widest application, and excellent comprehensive performance. This alloy has excellent corrosion resistance in fluorine and gas media, and also has excellent corrosion resistance to hot concentrated alkali solution. At the same time, it is also resistant to corrosion by neutral solutions, water, seawater, steam, organic compounds, etc. An important feature of this alloy is that it generally does not produce stress corrosion cracks and has good cutting performance.
Chemical composition of monel wire mesh:
Ni: balance; Cu:28-34; Si:＜0.5; Mn:＜2.0; C: ＜0.30; Fe: ＜2.0
Corrosion resistance of Monel wire mesh:
The alloy has excellent corrosion resistance in fluorine gas and its derivatives, and is more corrosion resistant than copper-based alloys in seawater.
Acid medium: M400 is corrosion resistant in medium with concentration less than 85%. M400 is one of the few important materials that can withstand high temperatures.
Water corrosion: In most water corrosion conditions, M400 alloy not only has excellent corrosion resistance, but also rarely suffers from pitting corrosion and stress corrosion. The corrosion rate is less than 0.25mm/
a. High temperature corrosion: The highest temperature of M400 in continuous operation in air is generally around 600°C. In high temperature steam, the corrosion rate is less than 0.026mm/
a. Ammonia: Due to the high nickel content of Monel 400 alloy, it can resist corrosion under ammonia and ammoniated conditions below 585°C.
Product features of Monel Alloy Wire Mesh: Monel 400 is a corrosion-resistant alloy with large dosage, wide application and excellent comprehensive performance.

It is also resistant to corrosion by neutral solutions, water, seawater, atmosphere, organic compounds, etc. An important feature of this alloy is that it generally does not produce stress corrosion cracks and has good cutting performance. The structure of Monel 400 alloy is a high-strength single-phase solid solution.
Corrosion resistance
Product corrosion resistance: Monel 400 alloy has excellent corrosion resistance in fluorine gas, hydrochloric acid, sulfuric acid, hydrofluoric acid and their derivatives. At the same time, it is more corrosion-resistant than copper-based alloys in seawater. Acid medium: Monel 400 is corrosion-resistant in sulfuric acid with a concentration of less than 85%. Monel 400 is one of the very few important materials that can resist hydrofluoric acid. Water corrosion: Monel 400 alloy not only has excellent corrosion resistance in most water corrosion conditions, but also rarely suffers from pitting corrosion and stress corrosion, and the corrosion rate is less than 0.025mm/a. High temperature corrosion: The highest temperature of Monel 400 in continuous operation in air is generally around 600℃, and the corrosion rate in high-temperature steam is less than 0.026mm/a. Ammonia: Due to the high nickel content of Monel 400 alloy, it can resist corrosion under anhydrous ammonia and ammoniation conditions below 585℃.
