Mike,
what you are saying is correct I agree with you one hundred percent. You
are saying that the bars are only cold treated on the surface and not to the
core, so when you take away that treated surface the bar becomes weak,
correct?

The bars I work with are not cold treated and sitting in an oven doesn't
change the molecular structure. The bars we run are treated to the the core,
so we can get away with scotching old bars without worring about losing that
surface treat.
It was a bad example I admit I assumed that DeLorean used the same material.
And I apologize for any confusion.

But there is one thing that I don't understand is that the process you
described is expensive even though Boing made the bars I don't see DeLorean
spending all that time and money on torsion bars especially 20 years ago on
a $25,000 car. Torsion bars were nothing new at that time for that type of
cold treating. Without the 269.8 lbs of force assisting from the gas springs
the doors won't even open on there own anyway.
The one gentlemen had said that his bars were discoloring and showing a
little rust. And another gentlemen had said that the bars were made from
stainless steel. If there were stainless they would have to be hardened to
get that tensil strengh, and if they are stainless there might be a thin
layer of ferrite iron on the surface of the bars
that would be the cause of the discoloration and rust.

Until we know what material and process Boing used to make the bars were all
blowing smoke. I don't know but I'm having fun. If there is any further
thread on this subject keep in mind that there is no bashing nessesary this
is a learning experience for all.
Keep the peace and drive stainless
Mike
