Monel 400 (UNS N04400, NCu30) The structure of Monel 400 alloy is a high-strength single-phase solid solution. It is a corrosion-resistant alloy with the largest amount, the widest application and excellent comprehensive performance. This alloy has excellent corrosion resistance in hydrofluoric acid and fluorine gas medium, and also has excellent corrosion resistance to hot concentrated lye. At the same time, it is also resistant to corrosion by neutral solutions, water, sea water, 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 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. â?² Acid medium: M400 is corrosion-resistant in sulfuric acid with a concentration of less than 85%. M400 is one of the very few important materials in durable hydrofluoric acid. â?² Water corrosion: M400 alloy not only has excellent corrosion resistance under most water corrosion conditions, but also pitting corrosion and stress corrosion are rarely found, and the corrosion rate is less than 0.25mm/a. â?² High temperature corrosion: The maximum temperature of M400 continuous work in the air is generally around 600�°C, and in high temperature steam, the corrosion rate is less than 0.026mm/a. â?² Ammonia: Due to the high nickel content of Monel 400 alloy, it can resist corrosion under anhydrous ammonia and ammoniation conditions below 585�°C.
