Steel Case Hardening


If your products use case hardened steel components, understanding the effects of alloy composition and heat treating process conditions on the microstructure and properties of the steel is critical for:

  • Selecting the most appropriate alloy and heat treating process for your application
  • Evaluating suppliers
  • Developing manufacturing processes
  • Solving quality problems

This course teaches:

  1. Basic process conditions for carburizing, nitriding, carbonitriding, nitrocarburizing, flame hardening, and induction hardening.
  2. Microstructure changes that occur during case hardening heat treating processes.
  3. Alloy composition and steel microstructure required prior to use the different case hardening processes.
