Q: I’m looking for a bolt that can handle salt air and be structurally sound with a tensile strength of about 115-120 ksi max – do I require a titanium grade 5 bolt because I know they are costly?
A: Probably not at that tensile strength. A Super Duplex bolt may be a good solution at an economic price point. Super Duplex 2507 bolts provide good corrosion resistance to salt water environments. They are also strong offering 125ksi UTS and 82ksi yield.
