I'm envisioning a gadget I can see a use for....

It would be made from spring steel, say coat-hanger diameter, in s
specific shape. Key to its use would be it could be bent in one way to
deploy it, but it would revert to its original shape.

What controls how much it can be bent without altering the final shape?

Umm. The modulus of elasticity????? Is this multiple choice?

RWL

The modulus of elasticity for all grades of steel is about the same.
Stainless is slightly lower.
