Q: I have a seawater application where the water can be stagnant or polluted. Is Monel bolts the best choice?
A: For stagnant seawater application we would usually suggest Titanium over Monel fasteners. Although Monel is very resistant to saltwater, it can experience pitting corrosion in stagnant water situations. There have been tests that shown Titanium to last almost two decades in tests of polluted seawater. So while Monel fasteners is excellent in moving water, titanium screws are usually the preferred material in stagnant water.
