Description
NON-ORIENTED ELECTRICAL STEEL FULLY PROCESSED
Non-Oriented Electrical Steel Fully Processed for sale. Electrical steels are divided into NGO (Non Grain Oriented) and GO (Grain Oriented) grades according to the magnetic behavior.
COLD ROLLED FUL LY PROCE SSED ELECTRICAL STEELS
Cold rolled fully-processed electrical steels may be delivered without insulation or insulated on both sides with insulation in order to achieve desired properties for various fields of application (higher surface
insulation resistance, improvement of punch ability and corrosion resistance, annealing).

- Surface insulation resistance depends on coating thickness
- In air long time (testing for 20000 hours at a given temperature in accordance with IEC 60085)
- In protective gas atmosphere (as stress-relief annealing). Non-Oriented Electrical Steel Fully Processed.
- It relates to the resistance to the most of lubricants, refrigerating mediums and The varnish producer tests the resistance to the specific medium only after the customer’s requirement
- Colour shades depend on the coating thickness and type of varnish applied
