Do I Need to Stress Relieve My Small Torsion Springs Made from Music Wire?

Click For Summary
SUMMARY

Stress relieving is not critical for small torsion springs made from .009" O.D. spring-temper carbon steel wire, commonly known as music wire. The springs in question will have dimensions of approximately .045" I.D. and .060" in length with two legs. While heat treatment is generally performed after heavy cold working to restore ductility, the specific application of these springs may not necessitate this process. Feedback from experienced users confirms that for small-scale applications, stress relieving can often be omitted.

PREREQUISITES
  • Understanding of torsion spring design and applications
  • Knowledge of material properties of music wire
  • Familiarity with heat treatment processes
  • Basic principles of cold working in metal fabrication
NEXT STEPS
  • Research the effects of cold working on music wire properties
  • Learn about heat treatment techniques for carbon steel
  • Explore best practices for designing small torsion springs
  • Investigate alternative materials for spring applications
USEFUL FOR

Engineers, hobbyists, and manufacturers involved in spring design and fabrication, particularly those working with music wire and small-scale applications.

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.

Usually after a heavy cold working to form something, a heat treat is performed to bring back some ductility.
