EN 10106 Grade M330-65A: Premium Non-Oriented Electrical Steel with Guaranteed Magnetic Performance
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.

| Application areas | The fully processed steel is designed for the manufacture of magnetic circuits for motors, transformers and other electrical equipment. The principal applications are in the electrical engineering, domestic appliance, automotive and building industries. Low loss fully processed steels are also suitable for shielding applications at low frequencies (e.g. housings around electrical systems). | |
| Coating | This standard grade is available non-insulated or varnished with any of the coating types described in the following link https://industry.arcelormittal.com/catalogue/D28/EN . | |
| Other | Recommendations for use The are obtained without heat treatment after stamping. The material as supplied possesses all the required magnetic properties. | |
