Newbie here...I'm making small torsion springs from .009" O.D. spring-temper carbon steel wire also known a music wire from the supplier. I don't have the material in my hands yet so I don't know if it is coated. They will only be something like .045" I.D. x .060" long with two legs. My question is, do I need to stress relieve the springs...I don't see that this is critical for my application but would like some feed back.
