About Monel 400 Product 대한민국

1. The corrosion resistance of Monel is generally superior to that of nickel and copper. It is more resistant to corrosion from reducing media than pure nickel, and is more resistant to corrosion from oxidizing media than pure copper. It has excellent corrosion resistance to sulfuric acid, phosphoric acid and carbon. good. It is particularly resistant to hydrochloric acid corrosion and has excellent corrosion resistance to hot concentrated alkali. Monel400 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. Monel400 is a deformable nickel-copper nickel-based alloy. It has good resistance to seawater corrosion and chemical corrosion, and has strong resistance to chloride stress corrosion cracking. This alloy is one of the few that can be used in fluorides. It has good resistance to oxide stress cracking corrosion in hydrofluoric acid and fluorine gas media, such as seawater and salt water environments. Monel 400 also has very good corrosion resistance in moderately concentrated alkaline and salt solutions. In cooler alkaline environments, the alloy is used in weak acid environments such as sulfur and hydrogen fluoride.

2. 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 hydrofluoric acid.

3. Water corrosion: Monel400 alloy not only has excellent corrosion resistance under most water corrosion conditions, but also pitting corrosion, stress corrosion, etc. are rarely found, and the corrosion rate is less than 0.025mm/a.

4. High-temperature corrosion: The maximum temperature of Monel400's continuous operation in the 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 Monel400 alloy, it can withstand corrosion under anhydrous ammonia and ammoniation conditions below 585°C.
