Cold rolled pole sheet grades are classified according to their yield strength (EN 10265:1995). As well as guaranteed mechanical properties, they have guaranteed magnetic properties, but unlike other electrical steel grades, their magnetic properties are determined under direct current (DC) conditions. Full magnetic characterisation curves in DC and also at various frequencies are available on request.

This data sheet deals with the cold rolled grades that conform to the standard.

High yield strength values allow these grades to withstand strong electromechanical forces. As well as excellent DC magnetic properties significantly superior to the requirements of the standard, these grades perform well on loss and induction levels at 50 Hz, thanks to a special chemical composition.

Cold rolled pole sheet grades are designed for large high-speed machines because of their excellent combination of mechanical strength and magnetic performance.

These properties are obtained without heat treatment after stamping. The material as supplied possesses all the required magnetic properties.
