Product advice on steels to be used for:
Important specification
  • Higher frequency losses

Oven transformers require steel with guaranteed magnetic properties.

Non-oriented fully processed electrical steels (M230-35A, or M270-35A) are a right choice for this application.

For an increased efficiency and a higher specific power rating, fully processed high permeability grades (M330P-35A, or M330P-50A) can be also recommended.

Grain-oriented electrical steels (M145-35S or M155-35S) can also be used. They are supplied in the fully processed state and have guaranteed magnetic properties. 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.
