Heat treatment

Diverse heat treatment processes enable us to influence the mechanical properties of the parts concerned. Contrasting requirements, such as ductility for cold forming and toughness, strength and hardness in the end product, can be addressed by appropriate heat treatment processes.

Influencing the grain structure by heat treatment.

A cold formed part without heat treatment


Annealing processes enable predefined material properties to be obtained, whilst also avoiding unintentional material toughening.

Case hardening

Case hardening produces components with a hardened surface layer and low-carbon softer core.


Tempering produces parts with simultaneously high levels of toughness and impact strength characteristics.
