Monel 401 Material Propertie

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. Monel401 alloy is more resistant to corrosion by reducing media than pure nickel, and more resistant to corrosion by oxidative media than pure copper. Monel401 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.
