tensile strength steel= 800Mpascals (M=Mega)
tensile strength 6AL-4V=900Mpascals
yield strength steel= 640Mpascals
yield strength 6AL-4V= 830Mpascals
Titanium will always be stronger, especially tensile (stretch test) compared to steel, however titanium is more susceptical to shock compared to steel. Because the bolt you are using is not under violent shocks it is safe to say that the titanium you have chosen is safe to use......this pm will not stand up in a court of law though
Aerospace grade 6AL-4V and any other aerospace graded titanium is no better than normal 6AL-4V. The difference between them is traceable paperwork with respect to the tests that are conducted on manufacturing each batch of said grade titanium. In short, all aerospace grade titanium is fully traceable from it's supplier through to its testing. Normal non aero grade does not have to be so traceable. If an aircraft drops out of the sky....they want to know why and therefore everything must be traceable. If a car crashes... no one gives a fuck.
So, if anyone offers you aero grade titanium remember that it is no better than normal titanium of the same grade ( it is no stronger than normal non aero grade) but will be more expensive due to the traceable tests that are conducted on each batch......you are helping to recover their costs of testing buy paying more.
