Monel 400

Monel 400
Monel 400 is a nickel-copper alloy with excellent corrosion resistance in a wide range of media, including seawater, hydrofluoric acid, sulfuric acid, and alkaline solutions. It exhibits good mechanical properties from low temperatures up to elevated temperatures, along with high ductility and excellent weldability. It is highly resistant to stress corrosion cracking in chloride environments and shows good resistance to erosion-corrosion. Widely used in marine, chemical, and oil and gas industries, it provides reliable performance in both corrosive and high-temperature applications.
