Q: Is Monel rust proof?
A: Monel is one of the primary materials we recommend for saltwater corrosion resistance. Monel bolts are also the go-to material by the navy for marine and seawater conditions. In terms of water, saltwater and sea air, Monel is very corrosion resistant – so it won’t rust in atmospheric conditions, however given a strong enough corrosive acid Monel like any metal can corrode when its limits have been exceeded.
