Anti-roll bar material
Anti-roll bar material
(OP)
I have an anti-roll bar with an effective length of 9 inches made from 0.625 x 0.058 4130 heat treated to RC33-35. Does anyone know of a steel alloy, given the same OD will be 20 to 40 percent softer in torsion? Using a smaller tube diameter is not an option.
Thanks,
John

Changing steel grade and / or temper will I think only change the elastic limit, not stiffness (at least not to any significant degree). I think you'll find that to decrease stiffness while maintaining OD, you'll need to reduce wall thickness (or increase the length of the torsional section of the ARB, or the lever arms?).

I think you need to do something with the arms to make them provide the requisite flexibility in bending. That does assume that you can build up your own bar from separate pieces.

I don't know anything but the people that do.
