I'm not convinced that taking a slight bow out of a mild steel tubular
member will weaken it to any degree, also it's got to be much better than a
bent one WRT it buckling under compression?

Maybe, but the item in question is the track rod, not the ends. Do new TRE's
come with a new trackrod?

Oops.
Read TRE, not TR.
Carry on.

It is unlikely to be mild steel - it is probably a low alloy medium carbon
steel with carefully planned heat treatment.

It's very likely to be mild steel, actually. And in my experience
that's the case - soft as cheese. In normal use the rod, even with
partially seized rod ends sees little more that straightforward
tension and compression - nothing 'sophisticated' is needed. Mild
steel will do the job fine.
The buckling load is largely independent of the grade of steel and it
is only once buckling has occurred that a 'better' grade will show any
advantage.

they don't machine like mild steel. and they're a bastard to straighten.

I've only attacked old ones - they hacksawed easily. Straightening is
an issue but that's a geometry problem rather than a material one, I
think. It'll be a few years before I get a current production one to
play with!

They can do - a complete track rod is about £70 though. The adjuster
link, TRE's and tube with bracket are available sperately though.

I straightened a 110 rod once as a short-term fix - the new rod though is
not all that pricey if the ends are good. dunno if a disco one is more,
mind. The 110 one even including the ends wasn't silly money.
