Electrical steel

Steel is a material with a future, a material that is well suited to an age where resources have to be managed carefully. ThyssenKrupp electrical steel is used for the production of energy-efficient generators, transformers and electric drives, making a valuable contribution to conserving raw materials. We are also currently developing electrical steel grades especially for use in hybrid cars with electrical drive components. Yet again, steel is opening up new opportunities.

One center of electrical steel production at ThyssenKrupp is the cold rolling mill in Bochum. Here, hot strip from Duisburg-Bruckhausen is processed into non-oriented (NO) electrical steel. After pickling, cold rolling and annealing, the material can also be given a special insulating coating. We supply semi- and fully finished grades offering excellent processability, outstanding magnetic properties and superb energy efficiency.

Grain-oriented (GO) electrical steel is produced by ThyssenKrupp Electrical Steel at plants in Gelsenkirchen and Isbergues, France. This steel product, used in transformers, features a special microstructure developed in a complex manufacturing process. This highly advanced core material makes a significant contribution to minimizing core losses in the transfer and distribution of electrical energy.

Look forward and never stand still is the motto for electrical steel at ThyssenKrupp. We invest in research to develop new grades for demanding applications. We invest in production technology in order to offer our partners high-performance products at competitive prices. And we support our customers with service and advice – for example in the development of production strategies. In short, we are shaping an energy-efficient future with steel.
