EN 10265 Grade 250-400-TG 180
EN 10265 Grade 250-400-TG 180 introduction
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.
