Monel 400�, Nickelvac� 400, Nicorros� 400 Monel 400� is a nickel-copper alloy that is hardened by cold working only. Monel 400� has low corrosion rate in flowing seawater, therefore it is widely used in marine applications. Monel 400� also has excellent resistance to stress corrosion cracking in most freshwaters. Monel 400� can be used in temperatures up to 1000 �F. The alloy has great mechanical properties at subzero temperatures. Available forms are seamless pipe, welded pipe, seamless tube, welded tube, bar, wire, sheet, plate, forgings, pipe fittings and flanges.
