EN 10106 Grade M270-35A
EN 10106 Grade M270-35A introduction
Non-oriented fully processed electrical steel have guaranteed magnetic properties, in accordance with (or exceeding the levels required by) EN 10106:2015. As well as the maximum loss and minimum polarisation levels cited, full magnetic characterisation curves regarding losses, polarisation, permeability and apparent power at different frequencies are available on request.
This standard grade is available so that a steel grade can be selected according to the specific requirements of each application, from low alloy grades offering the advantage of excellent magnetic permeability, thermal conductivity and punchability to alloyed grades offering the advantage of very low losses, even at higher frequencies. A wide range of coatings is available, allowing further enhancement of punchability, reduction of interlaminar losses and improvement of corrosion protection.
Equivalent material: AISI M19, ASTM 36F155, JIS 35A270, IEC M270-35A5
