Has the following characteristics:

Monel400 is a corrosion-resistant alloy with high usage, wide applications, and excellent comprehensive performance. This alloy has excellent corrosion resistance in gas media and also has excellent corrosion resistance to hot concentrated alkaline solutions. It is also resistant to corrosion from neutral solutions, water, seawater, atmosphere, organic compounds, etc. An important characteristic of this alloy is that it generally does not produce stress corrosion cracking and has good cutting performance.

Metallographic structure of Monel 400:

The microstructure of Monel400 alloy is a high-strength single-phase solid solution.

Corrosion resistance of Monel 400:

Monel400 alloy has excellent corrosion resistance in fluorine gas, hydrochloric acid, sulfuric acid, and their derivatives. At the same time, it has better corrosion resistance than copper based alloys in seawater. Acid medium: Monel400 is corrosion-resistant in sulfuric acid with a concentration of less than 85%. Monel400 is one of the few important materials that can withstand acid. Water corrosion: Monel400 alloy not only has good corrosion resistance in most cases of water corrosion, but also rarely experiences pitting corrosion, stress corrosion, etc., with a corrosion rate of less than 0.025mm/a. High temperature corrosion: Monel400 operates continuously in air at high temperatures generally around 600 ℃, and in high-temperature steam, the corrosion rate is less than 0.026mm/a. Ammonia: Due to the high nickel content of Monel400 alloy, it can withstand corrosion under anhydrous ammonia and ammoniation conditions below 585 ℃.
