Having worked in the titanium business for almost 20 years, I can tell
you a little about bolts. If you buy standard titanium bolts made for
the chemical industry, you would get somewhat weak bolts. These would
be around 50,000psi yield strength much similar to a hardware store
stove bolt (little stronger). These are made from commercially pure
titanium and not alloyed to add strength.
If you bought aircraft quality the strength would go up considerably
to about 70,000psi or more. The alloys like ti-6al-4v would be what
you would be looking for and be very common. Other alloys are even
stronger and may be harder to find.
One way to find out if what you are trying to do is safe is to find
the existing bolt strength either from the manufacture of from the
letter stamped on the bolt head, if there is one. For example many
automotive bolts are stamped and used in specific locations. Compare
this strength to the titanium alloy bolt.
The alloy bolt, although not good for many chemical applications
should not corrode in your application.
Hope this helps.
