Monel 400 corrosion properties
|
Medium |
|
Monel 400 the corrosion resistance to non-oxidative acids, especially hydrofluoric acid, is very good, all concentrations of hydrofluoric acid can be used at room temperature, in the concentration of 10% hydrofluoric acid can use boiling point. |
|
Monel 400 also have good corrosion resistance to hot concentrated alkali, but not as good as pure nickel. Resistant to seawater, low concentration hydrochloric acid and various organic substances |
|
Monel 400 corrosion resistant to oxidizing acids and other strongly oxidizing solutions, molten salts, molten metals and high temperature sulfur-containing gases. |
