Description

This Hot rolled pole sheet grade is 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, its magnetic characterisation is determined under direct current (DC) conditions.

High yield strength values allow this grade to withstand strong centrifugal and electromechanical forces, both in static and dynamic conditions. The DC magnetic properties are excellent and significantly superior to the requirements of the standard. For the hot rolled pole sheets with yield strength guarantee up to 400 MPa the flatness guarantee is maintained after laser cutting of the laminations. For the hot rolled pole sheets with yield strength guarantee beyond 400 MPa the flatness remains excellent, even after laser cutting of the laminations.

Technological properties

Property
Application areas

Hot rolled pole sheet grade can be supplied in the form of coils or sheets. It is designed for large high-speed machines because of their excellent combination of mechanical strength and good magnetic performance. Good magnetic properties are of major importance for the performance of the poles, whereas excellent mechanical properties are needed for the rims.

Coating

Hot rolled pole sheet grade is available non-insulated. It can be supplied with the hot rolled oxide layer or pickled. When pickled, they are protected with Easyfilm® dry coating, which offers protection against atmospheric corrosion for a period of three months

Other

These properties are obtained without heat treatment, whatever be the mechanical or thermal cutting process used to obtain the desired lamination diameter. The material as supplied possesses all the required magnetic properties.
