high tensile bar

[Rhett]

Ive just had a new tie rod made from 32mm high tensile solid bar with himie joints at each end. Ihave to tow the car all the way to nsw this weekend for a comp but someone mentioned that high tensile bar will shatter. Is this true as i would hate to tow it all the way down to break a tie rod.

You wont have any problems with it shattering.

I'd guess that the steel alloy is 4140 - that is the alloy that I would choose (for a number of reasons) if I needed an alloy tie rod. Even if it was higher strength than that, I would worry about breaking the rest of your steering before it would bend or break.

was it high tensile bar or hardened bar?

The stuff they use to run bearings on.

hmmm, linear bearing shaft. i'm not sure what it's made of but i do know this...
the outside skin on the bar is hard as hell(read brittle)
the inside is quite soft and can be machined readily.
i don't know if it will be sufficiently brittle to be a problem or not, but why was this material used in the first place?? when 4140 machines so well and is cheaper, steering and suspension are not areas to cut corners on!

Im guessing that was what it was. Thw bloke that done it for me was an engeneer and I told him what I run into with it. Im guessing is not going to shatter though.

4140 is the go i made my track rod from this Dia 32mm and had a 20mm hole drilled through and have never had a problem since. The hole up the guts was for reduced weight and in theory should be better at returning to its original shape than solid.
