wholesales low price nickel alloy monel 400 plate
Corrosion resistance:
Monel's corrosion resistance is generally better than nickel-copper. It is more resistant to corrosion by reducing media than pure nickel, resistant to corrosion by oxidizing media than pure copper, and has very good corrosion resistance to sulfuric acid, phosphoric acid and carbon. In particular, it is resistant to hydrochloric acid corrosion, and also 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, which has good seawater corrosion resistance and chemical corrosion resistance, and strong chloride stress corrosion cracking resistance. This alloy is one of the few alloys that can be used in fluoride. It has good resistance to oxide stress cracking corrosion in hydrofluoric acid and fluorine gas medium, such as sea water and salt water environment.
In medium concentration alkaline and salt solutions, Monel 400 also has very good corrosion resistance.
In a colder alkaline environment, the alloy is used in a weak acid environment such as sulfur and hydrogen fluoride.
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.
Water corrosion: Under most water corrosion conditions, Monel400 alloy not only has excellent corrosion resistance, but also pitting corrosion and stress corrosion are rarely found, and the corrosion rate is less than 0.025mm/a.
High-temperature corrosion: The maximum temperature of Monel400 continuous working in air is generally around 600ºC, and the corrosion rate in high-temperature steam is less than 0.026mm/a. Ammonia: Due to the high nickel content of Monel400 alloy, it can withstand corrosion under anhydrous ammonia and ammoniating conditions below 585ºC.
