Hi to all,
does someone know what kind of steel is used for the sway bars in general? I am interested in having a sway bar fabricated, but I need to know the type of steel used. For the early 911 the front sway bar is pretty easy to fabricate, so I would like to try...
Thank you
Andreas

I took the front anti-sway bar off of my 911 and took it to a place that burned a small amount of metal away and then ran the smoke through a spectrum analyzer and they told me that the metal was a silicon manganese steel. They also did a hardness test and it was a 32 on the Rockwell C scale. I did some research and found that it is not as good a spring material as spring steel but a little better that 4130. It is however more common in europe and not as easily found as 4130.
I ended up using 4130 that was solution heat treated and then hardened to a 32C Rockwell after I had the machining performed.
That was three years ago with many auto-Xs and track events with no problem.
I hope that this helps, Steve Frew.
