Hardening and tempering

Component properties can be improved by carefully chosen heat treatment processes:

  • increased hardness and toughness
  • elimination of undesirable work hardening
  • partial hardening of precision components



Maximum customer benefit and flexibility follow from the use of in-house heat treatment processing, featuring every major technique, such as annealing, tempering, case hardening, carbonitridingand a range of special processes.


Annealing

Suitable annealing processes serve to alleviate the effects of work hardening.

Heat Treatment

Heat treatment to harden and temper can achieve the required toughness level and improve on its even distribution.

WireWork hardenedHardening:
800 - 900°C		Tempering:
450 - 650°C

Case hardening and carbonitriding

Case hardening and carbonitriding enable the generation of hard pressure and wear resistant surfaces.
