Heat Treating

Heat treating includes several thermal and metalworking processes uses to change the properties of metal and improve its performance and durability. Heat treating can also improve the formability of metals or improve its strength. Almost all processes include these three steps: heating, soaking, and cooling.

Iron and steel are the most metals used in heat treating, though other metals and alloys are compatible with many of these processes as well. The five standard heat treating processes include:

  • Hardening
  • Case Hardening
  • Annealing
  • Normalizing
  • Tempering
