specific weight and strength figures handy though I well know that it is
considerably heavier than aluminum.... probably closer to 60% of the weight
of steel.  Strength is a very open ended thing... many alloys and tempers
exist..... in general it is capable of reaching strengths comparable to
those of high carbon steel when properly alloyed and tempered.... I don't
believe it exceeds anything you can do with steel for strength.   As we have
no idea what alloy and temper are to be found in the titanium bolts..... and
we have no idea what steel bolts we are comparing to it is not really
possible to make a statement  accurately.  It is fairly easy to
verify the weight figures.... check at the following URL:

one should be able to find weights and strengths there...... As you well
know steel bolts do not utilize the strongest alloys or tempers of steel....
can you assume that titanium bolts do?   There is no doubt that in some
instances they are a suitable substitute for steel.... There are many
properties other than just tensile strength involved here....in others they
are not a suitable substitute.   Broad generalizations ..... especially
uninformed ones do us all a disservice.... not that we are not occasionally
guilty of them.
