ELECTRICAL STEEL SHEET

An electrical steel sheet has an insulating coating on a steel sheet surface. The insulating coating includes one or more selected from an inorganic salt, an oxide, and an organic resin. The insulating coating includes the inorganic salt and/or the oxide in an amount of 50% or more by mass in total...

Beschreibung
Zusammenfassung:	An electrical steel sheet has an insulating coating on a steel sheet surface. The insulating coating includes one or more selected from an inorganic salt, an oxide, and an organic resin. The insulating coating includes the inorganic salt and/or the oxide in an amount of 50% or more by mass in total based on the total mass of the insulating coating. The insulating coating has a fluorine concentration ranging from 2 ppm to 130 ppm. The insulating coating is free of a chromium compound. The insulating coating of this electrical steel sheet has excellent coating compatibility.
