Re: Replacing lead Keel bolts

Titanium is the best choice. It will never corrode in salt water. The only substance that can penetrate its protective oxide coating is a strong acid, like hydroflouric.

Silicon Bronze is more corrossion resistant than stainless, both 18-8 and 316 in salt water. No advantage in fresh water. Just gotta make sure you get good quality bolts. We tested silicon bronze against brass at work for a non-magnetic application. They were only half as strong as they were supposed to be. So, we abandoned them.
