Monel 400 features

Monel400 is the corrosion-resistant alloy with the largest amount, the most versatile and excellent comprehensive performance. The alloy has excellent corrosion resistance in hydrofluoric acid and fluorine gas media, and excellent corrosion resistance to hot concentrated alkali liquor. It is also resistant to corrosion by neutral solutions, water, sea water, atmosphere, organic compounds, etc. An important feature of this alloy is that stress corrosion cracking is generally not produced and the cutting performance is good.

Metallographic structure of Monel 400

The structure of the Monel 400 alloy is a high strength single phase solid solution.

Corrosion resistance of Monel 400

Monel 400 alloys have excellent corrosion resistance in fluorine, hydrochloric acid, sulfuric acid, hydrofluoric acid and their derivatives. At the same time, it is more resistant to corrosion in seawater than copper-based alloys. Acid medium: Monel 400 is corrosion resistant in sulfuric acid with a concentration of less than 85%. Monel400 is one of the few materials that are resistant to hydrofluoric acid. Water corrosion: Monel400 alloy has excellent corrosion resistance in most water corrosion conditions, and pitting corrosion and stress corrosion are rarely found. The corrosion rate is less than 0.025mm/a. High temperature corrosion: The maximum temperature of Monel400 working continuously in air is generally around 600 °C. In high temperature steam, the corrosion rate is less than 0.026 mm/a. Ammonia: Due to its high nickel content, Monel400 alloy can withstand corrosion under anhydrous ammonia and ammoniating conditions below 585 °C.
