4. Physical properties: density g cm3 ( melting point ( 1300 1390) tensile strength b mpa (480) yield strength (170) elongation 5% (35).

Five: Overview: 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. Acid medium: corrosion-resistant in sulfuric acid with a concentration of less than 85%.

Monel400 is one of the very few important materials that can resist hydrofluoric acid. Water corrosion: Monel400 alloy not only has excellent corrosion resistance in most water corrosion cases, but also porosity and stress corrosion are rarely found, and the corrosion rate is less.

High temperature corrosion: The high temperature of continuous work in the air is generally about 600, and the corrosion rate is less than that in high temperature steam. Ammonia:

Due to the high nickel content of the alloy, it can resist corrosion under anhydrous ammonia and ammoniation conditions below 585.

Monel400 copper-nickel alloy is resistant to seawater corrosion

Monel400 Introduction:

It is a corrosion-resistant alloy with the largest amount, the most extensive use and excellent comprehensive performance. This alloy has excellent corrosion resistance in hydrofluoric acid and fluorine gas media, and also has excellent corrosion resistance to hot concentrated alkali. At the same time, it is also resistant to corrosion by neutral solutions, water, seawater, atmosphere, organic compounds, etc.

High-temperature and corrosion-resistant alloys are widely used in seawater and other fields. An important feature of this alloy is that it generally does not produce stress corrosion cracks and has good cutting performance.
