Metallurgy of Steel Case Hardening

This online course discusses common steel case hardening processes and how they are used to modify the surface layers of steels to obtain specific mechanical properties. Participants will learn about the process parameters and how they affect case composition, depth, microstructure, and properties. The course takes one hour to complete.

What Will You Learn

By participating in this online course, you'll be able to:
  • Describe the thermal cycles and significant process variables for six common case hardening processes
  • Explain the case microstructures that result from the six common case hardening processes
  • Describe the effects of case hardening process parameters on case depth, microstructure, and hardness of case hardened steel
  • Explain two ways to measure case depth of carburized steel
  • List common problems encountered with case hardening processes and how to prevent these problems
