Sway Bar Design - Heat Treatment
Sway Bar Design - Heat Treatment
(OP)
I am fabricating a rear sway bar on a race car. My question is related to what type of steel to use and the appropriate heat treatment to specify.
I was planning on using 4130 - 1.25"O.D. x 0.095 wall
Would 4140 or 4340 steel be something to consider.
Based on my stress calculations, I need a bar that will end up with a yield point of 167,500 psi.
Thanks.

RE: Sway Bar Design - Heat Treatment
With stresses that high, I would consider using something other than 4130. What is the length of the bar and how much twist are you expecting? As you already know, it would be nice if you could use 4130 since it is inexpensive and available in many diameters and wall thicknesses.

What is the diameter - OD and ID?
