Heat Treat - Hardness Verificationheat treat and hardness verification


Eddy current technology is the answer to a variety of manufacturing quality challenges. With eddy current equipment from Criterion NDT users can test metal components, magnetic and non-magnetic bar, tubing, and wire products to identify physical, structural and metallurgical conditions.

  • Verify heat treat conditions
  • Confirm proper case depth and location
  • Verify alloy content
  • Find hidden metallurgical, material and mass displacement anomalies


Multi-frequency testing with the InSite can even uncover unanticipated conditions or “freaks” - these are the faults that other eddy current testers will miss and may be the ones that can result in catastrophic failure or expensive product recalls.
