Ultra low loss steel sheet with excellent adhesion

摘要

Problem to be solved: to provide a very low iron loss oriented electromagnetic steel plate having excellent adhesion to the film without causing the peeling off of the insulating coating, even if stress is applied to the bending processing portion after the annealing is performed in the bending process. Solution: in the oriented electrical steel sheet formed of a metal nitride, a metal carbide or a metal carbonitride on the surface of a steel plate having no forsterite coating, it contains chlorine of 0.001 to 1 mass% in the ceramic coating . No selection
