Monel 400 alloy Metallurgical structure
Monel 400 is the solution of binary alloys. Because nickel and copper can be either a percentage of solubility, so single-phase alloys. Has a face-centered cubic lattice structure.

Monel 400 alloy Corrosion
Monel 400 alloy for many reducing media showed corrosion resistance. In the oxidizing medium is usually more resistant to erosion than the ability to contain higher copper alloy. This versatility makes the alloy is suitable for a variety of environments.

Monel 400 is widely used in marine engineering. The alloy products in seawater flow showed a lower corrosion rate, but in a static environment, but it will appear crevice corrosion and pitting. The alloy in most fresh and industrial waters are also resistant to stress corrosion cracking and pitting performance.

Monel 400 Special corrosion hydrofluoric acid all concentrations, even up to the boiling point. The alloy used in all engineering alloys is probably the most corrosion resistance. The alloy for reducing many forms sulfuric acid and hydrochloric acid also has corrosion resistance.
