GRADE 2 Titanium bolt Strength
Ok been trying to figure out a comparison and the info I find is conflicting. Some say grade 2 titanium is weaker than steel grade 2 and others say it's comparable to steel grade 5
I want to change from a Steel grade 5 bolt to the next size up Titanium grade 2, by my calc bout a 31% weight reduction because of the next larger size. It's a pull load so not worried bout shear

I know as much as I can learn and try to keep an open mind to anything!
If I didn't overthink stuff I wouldn't be on speedtalk!

Re: GRADE 2 Titanium bolt Strength
What’s the application? We use them all over the dirt midget and never have failure, even in certain places like shock bolts where we used to use 1/2-20 and have went titanium and down to 3/8 size by changing eyelet in the shock. Smith titanium and ti-22 as well Astro are all good to deal with.
Re: GRADE 2 Titanium bolt Strength
Yah I wouldn't hesitate to downgrade size in many spots. I don't wanna go into detail atm for a couple reasons. But it's actually more like 2 sizes larger bolt as it's common to upgrade it one size from stock, since the stock size sometimes breaks.

Re: GRADE 2 Titanium bolt Strength
It appears Grade 5 Ti 6al-4v is what you might want to consider.
It has a strength similar to a Class 10.9 but its stretch will be considerably more due to a much lower Young’s modulus (E) as compared to steel.

Re: GRADE 2 Titanium bolt Strength
Gotcha on application. We use them fir the radius rods shocks headlocks and wheel centers brake rotor to hat and torsion bar hardware jacobs ladder and I’ve yet to see a failure on any that wasn’t caused by a crash. We buy them at a local open wheel specialty shop. He sticks them in bulk in the common sizes and as well as some packaged specialty stuff.

I agree Ti64 would be more ideal BUT...Rick! wrote: ↑Sat Mar 27, 2021 8:21 am It appears Grade 5 Ti 6al-4v is what you might want to consider.

Re: GRADE 2 Titanium bolt Strength
I can't see personally use of Grade 2 Ti on a race car in any application that failure would cause an accident. Even Ti Grade 5 IMO should be used thoughtfully, as Ti is reported to be between Alum and Steel on its fatigue limits.
Re: GRADE 2 Titanium bolt Strength
Got any data to say why? Unless I find tensile strength of the exact Ti grade 2 bolt like I can for steel...

Re: GRADE 2 Titanium bolt Strength
Was just trying to look into Ti bolts more and found Cadmium plating causes embrittlement with Titanium, also silver but that's much less likely to happen than a cadmium plated nut/washer/bushing/bracket used with Ti hardware

Re: GRADE 2 Titanium bolt Strength
Grade 5 Ti is corrosion resistant without plating. (ref link above). Electro plating a Gr 5 Ti bolt doesn’t pass the “good quality screw” sniff test. Mechanical plating like zinc flake or the use of electroless nickel are better options.
What’s your projected weight savings with Ti hardware?

Re: GRADE 2 Titanium bolt Strength
Titanium is corrosive resistant in general from what I've read.
The embrittlement from Cadmium plating I mentioned was like if using a Ti bolt with say a steel cadmium plated nut
Weight savings are savings if your willing to put the time and money into them. Other means and materials are often cheaper but in this case it's steel or Ti

Re: GRADE 2 Titanium bolt Strength
Why what? The seriousness of a bolt failure in a race car in a suspension application, the difference in properties of Ti in grades 2 and 5 , or the relative fatigue limits of Ti being between Steel and Alum?
Re: GRADE 2 Titanium bolt Strength
The one your not being a smarta$$ about

That’s not how hydrogen embrittlement works.BOOT wrote: ↑Sun Mar 28, 2021 9:00 pm Titanium is corrosive resistant in general from what I've read.

If you research titanium bolt hydrogen embrittlement, you should find a reasonable study by hynickelalloy.com. Hydrogen is “installed” during manufacturing and or electroplating processes, not from rubbing a Cad plated nut on it.
