    \nMonel 400 is virtually immune to general “rusting” (iron oxide formation) and chloride stress-corrosion cracking in seawater. However, it may tarnish or turn green (patina) over time.

Engineers frequently face the dilemma of choosing between two titans of the non-ferrous world: Monel 400 (UNS N04400) and Copper-Nickel 70\/30 (C71500).
