Titanium Bolts for Strength of Grade 8 in Saltwater

Q: We have a fastener application requiring the strength of a Grade 8 bolt (per SAE J429) and the corrosion resistance equivalent of 316 SS (or better). This fastener will be exposed to a marine environment, so corrosion resistance is critical.

A: If you application requires the strength of Grade 8 and to be corrosion resistant in a marine environment, Titanium Gr5 is the way to go. Inconel 625 will certainly work as well but be a little more pricey.
