Monel 400

UNS N04400

Monel® was created by the International Nickel Company and patented in 1906. The patent has expired and it is available from a variety of sources. Alloy 400 is versatile and is used to resist both acids and alkalis. Seawater applications are common. A variant is Alloy 405 (UNS N04405). It contains slightly more sulfur, which improves machinability.
