Annealing is defined as the treatment of a workpiece at a certain temperature with a certain holding period and a subsequent cooling which is adequate for achieving the desired material properties.

Important annealing treatments:

  • normal anneling
  • stress relief anneling
  • soft annealing
  • spheroidizing (GKZ annealing)
  • large-grain annealing
  • recrystallization annealing
  • solution annealing

Adequate Systherms furnaces for this process:

  • horizontal heat treatment furnaces type VWC / VWQ
  • vertical heat treatment furnaces type VWS (Bottom Loader)
  • horizontal tempering furnaces, directly heated type VAD
  • tempering furnaces type VA
  • chamber furnaces type LA
