Re: Cold rolled steel, flats or square for use as rails.

So that brings me to another question.

Firstly yes the stainless steel seems to be the most logical so far.
How will stainless steel go for a bearing surface. I think from
memory SS is harder than normal mild steel? Yes??

And then why do all the other manufacturers use either mild steel
unground ( cold rolled flats,torchmate) and then others use hardened
and ground steel.

I can't say that I have seen any stailess steel rails made out of flat
or square stock. Maybe the Hiwin type and thompsons are all SS, I
don't know.
