FINAL STRESS TEMPERING

Final Stress Tempering is performed to remove machining stresses before a final machining operation to tighten tolerances.

Capability for Batch-Type Tempering Treatments

  • All of ThermTech’s Final Stress Tempering treatments are accomplished in our batch-type tempering ovens that are temperature uniform and certified as AMS-2750 compliant.
  • We have the ability to vacuum temper dies when concerns about oxidation prohibit open-air tempering.
  • We can accommodate most dies regardless of shape or size.
  • Most frequently, we temper large H-13, H-11, and P-20 dies.

Process of Final Stress Tempering

Final Stress Tempering is performed at a temperature high enough to relieve stresses, but not in excess of previous tempering temperatures used during the hardening cycle of your tool. This is done in order to inhibit size change and preserve mechanical properties.
