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.
| recrystallisation annealing 550 to 600°C | normalising above the GSK limit |

Heat Treatment
Heat treatment to harden and temper can achieve the required toughness level and improve on its even distribution.
| Wire | Work hardened | Hardening:
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.
| Wire | Work hardened | Hardening:
800 - 900°C | Tempering:
180 - 250°C |
