Annealing

Technology

Annealing achieves numerous different requirements for component properties. Homogeneous structures can be manufactured, internal tensions are reduced and the component properties are optimised for further mechanical processing. With our technology and different annealing processes we can fulfil any requirement whatsoever. Our material specialists will be glad to assist you in choosing the suitable process for your application.

The annealing processes

Stress-relief annealing 
Internal tensions in components as a result of cold forming, structural Transformation, thermal loads or metal-cutting processes can be reduced with no significant changes in the structure and mechanical properties.

Soft annealing 
Soft annealing is an annealing process at a temperature just below the lower transformation point with subsequent slow cooling in order to achieve components with a soft condition.

Solution annealing 
Solution annealing is used primarily with austenitic steels, in order to dissolve alloy elements homogeneously in the matrix and to achieve even, homogeneous structures and material properties. It is also used to eliminate tensions resulting from cold hardening.

Spheroidizing 
Spheroidizing is a special type of soft annealing that aims to achieve a structure with very good machining properties. This treatment is very important for subsequent cold forming, for example.d material properties. It is also used to eliminate tensions resulting from cold hardening.

Normalizing
Coarse-grained and uneven structures of cast, welded and hot formed steels are transformed into new, homogeneous and fine structures.
