THE PROCESS

 

STRESS-FREE ANNEALING

 

Any stresses, either inherent or introduced via mechanical load, are countered. Components with low machining allowance should be subject to stress-free annealing prior to heat treatment (hardening, nitriding, etc.)

 

NORMAL ANNEALING

 

Welding, bulk deformation (forging at high temperatures) or long dwell times during hardening can lead to the formation of coarse grain.

Normal annealing of ferrous materials aims to bring uneven, coarse-grained structures into a normal, even and fine-grained state.

 

SOFT ANNEALING

 

Soft annealing creates a state that is sufficiently softer and stress-free for the purpose of your material. The material can be re-hardened after soft annealing.

 

RECRYSTALLISATION ANNEALING / DIFFUSION ANNEALING

 

Hardness increases through cold forming are reversed. The material can be cold formed again.

 

BENEFITS

 

- the static of your material is improved

- strength is increased in many cases

- stresses are relieved

- the material can be processed (machined) either again or to a better degree

- negative effects from deformation processes are reversed
