Induction Hardening

UltraGlow® Induction Hardening

UltraGlow® Induction Hardening is a form of heat treatment in which a steel or cast iron part is heated by electromagnetic induction, immediately followed by rapid cooling (quenching). Upon quenching, the metal undergoes martensitic transformation, significantly increasing its hardness.

Induction hardening can be used to harden only select areas of a metal part without affecting the properties or distorting the remainder of the part. UltraGlow® Induction Hardening, a heat treat process offered at our Waterloo, IA facility can be used to harden select areas, soften or anneal select areas, and more! 

Benefits of UltraGlow® Induction Hardening:

  • Increased surface hardness, strength and wear resistance
  • Deep case with tough core
  • Parts may be tempered after induction hardening to adjust hardness level as desired
  • Selective hardening process with no masking required
  • Areas which require welding after heat treatment may be left soft
  • Relatively minimal distortion
  • Allows use of low cost steels such as 1045
  • Frequently the most economical treatment method per pound

Advanced Heat Treat Corp. UltraGlow® Induction Heating Capabilities:
