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. 

Q: Does Inconel crack?

A: Any material can crack under the wrong conditions. This would typically happen if you expose the Inconel bolts for the following situations:

1. Corrosive materials or concentrations of corrosive materials outside their capabilities.

2. Temperatures that would exceed their maximum usable temperature. This may not make them “crack” per say but would weaken their material structure, causing failure.

3. Also, when you utilize an Inconel bolt in a situation that exceeds their strength capabilities this will also cause bolt failure or “cracking”.

4. Or the combination of stress and corrosion (Stress Corrosion Cracking)
