I have aquired a length of 9/16 square torsion bar from a broken tail lift.

Before I go about destroying drills and milling cutters. Could someone tell me, can this material be milled/drilled readily or will it need some form of heat treatment to soften it?

I'm guessing it is some grade of spring steel. It's a nice lump of stuff that I can get more of, if it's good.

There is a chance it is 5160 Steel and as is likely to be difficult to machine but once annealed should be reasonable.

If I cut it into 6" or so lengths and toss them in my wood burning stove for a few hours and leave to cool, do you think it will soften them up?

I might just try it, and do a before and after test drilling.

Had a bit of broken 1 inch by 5 inch by 10inch leaf spring recently. The shaper dealt with it via both carbide and hss tooling. Only the outer skin was resistant so it was probbly a type of case hardened steel, like a sword, tuff skin only
