Description

Non-oriented fully processed high permeability electrical steel has 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 this steel is also higher than the conductivity of the fully processed standard grades.

The high permeability levels of this grade 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.

This material data has been provided by ArcelorMittal.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
