We are manufacturers, suppliers and exporters of Monel 400 material.
Common Trade Names: 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 oF. The alloy has great mechanical properties at subzero temperatures.
