Monel 400 Material Properties

The chemical composition of the alloy is mainly composed of 30% Cu and 65% Ni with a small amount of Fe (1%-2%). Due to the difference in chemical composition, it can have a variety of alloy grades, but there is no significant difference in corrosion resistance between them. Monel400 alloy is more resistant to corrosion by reducing media than pure nickel, and more resistant to corrosion by oxidative media than pure copper. Monel400 is a deformable nickel-copper-based nickel-based alloy with good seawater corrosion resistance and chemical corrosion resistance, as well as 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 fission corrosion in hydrofluoric acid and fluorine gas media, such as seawater and saltwater environments.

Advantage

1. Outstanding corrosion resistance in diverse environments.

2. High tensile strength and toughness at elevated temperatures.

3. Easy formability, machining, and welding due to ductility.

4. Low permeability to hydrogen gas for gas-tight applications.

5. Resistance to erosion and cavitation damage in high-velocity flows.

6. Retains mechanical properties across wide temperature ranges.

7. Long service life, reducing maintenance costs over time.

8. Versatile applications across marine, chemical, aerospace, and more.
