I make jewellery, so all my experience in this area is in gold, silver, and platinum; whenever I twist bars of these metals, I get reduction in length. I always have to allow for the reduction in the length of the starting bar.

I haven't tried it with steel or iron.

it is all basic induction.

If you want me to pull it all through a draw plate. You can but I'm sure there are others who can explain ductility.
