D22 - Fully processed high permeability and high thermal conductivity grades
These grades generate not only increased efficiency, but also a higher specific power rating, which is an important aspect for traction motors for locomotives, like this ICE-3 high-speed train.

Available grades:
Thickness 0.35 mm
Thickness 0.50 mm
Thickness 0.65 mm
Properties
Non-oriented fully processed high permeability electrical steels have guaranteed magnetic properties significantly superior to the requirements of EN 10106:2015, particularly regarding the polarisation levels obtained. Full magnetic characterisation curves are available on request, as well as thermal conductivity data. The thermal conductivity of these steels is also higher than the conductivity of the fully processed standard grades.
Advantages
The high permeability levels of these grades allow a reduction of the magnetising current required for a given air gap flux. This increases the efficiency of the machine and also makes it possible to increase its specific power rating, thereby reducing the machine's dimensions. High thermal conductivity levels are important, since they facilitate heat evacuation from the machine.
Applications
High permeability is particularly useful for applications such as ballasts and motors, because it makes it possible to build machines that meet the most stringent environmental regulations. High thermal conductivity is a significant advantage for large machines.
Recommendations for use
The above properties are obtained without heat treatment after stamping. The material as supplied possesses all the required magnetic properties.
