Q: I have a high strength application that requires resistance to damp salt air and occasional sea splash, I’m using Monel 400 but it’s not holding up the the 75ksi of yield I need. Lots of broken bolts? Is is corrosion or strength? Thoughts?

Q: Is AL6XN a steel or nickel alloy? Trying to figure out if it would perform as well as Monel in seawater.
Q: I have a salt water environment with high velocities and a lot of debris including sand, dirt and particles. Because of the amount of debris, I’m concerned about what material would work best.
A: Both Monel and Titanium can be good choices in this situation. Both perform extremely well in rapidly moving seawater. Titanium has an edge in performance if you have stagnant water but Monel may do better in high velocity erosive conditions. Generally speaking both Titanium and Monel will perform very well in high velocity salt water with sand and dirt.
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.
