Ken, the ductility problem with 6061 applies to 4130 as well.....if the part is to be bent, it ought to be made of relatively low strength material.

Bending 3/8" od 1/32" wall soft steel tubing with a bender is tricky enough, I can't imagine trying to bend 3/4" high strength 1/16" wall steel tubing without a bender without having it kink.

But I can imagine lopping off a piece of that tubing at a 45 degree angle and welding it back together with a 90 degree bend in it.
