Alloy 400 (aka Monel 400®) is a nickel-copper alloy that is hardened by cold working only. Alloy 400 has low corrosion rate in flowing seawater, therefore it is widely used in marine applications. Alloy 400 also has excellent resistance to stress corrosion cracking in most freshwaters and can be used in temperatures up to 1000ºF. it also has excellent mechanical properties at subzero temperatures.
