I'm working with some mild steel DOM tube and after milling a groove on the inside it's springing out into an oval shape. I'm looking at maybe stress relieving these. What temperature would that be done at? The inside surface is honed smooth and I'm concerned about scale building up during the process. Should I expect to see that? Or distortion to the size or straightness? Parts are 5.125" dia. x 5/16" wall x 23.375" long.
