The chrome the directivity electromagnetic steel sheet and its insulated membrane medicine which possess the insulated membrane which is not included

摘要

This invention being the corrosion-resistant characteristic, resistance annealing characteristic and directivity electromagnetic steel sheet product where membrane tension and the like is superior and something which offers the treatment agent the chrome at the time of insulation processing which designates the phosphate which is not included as the base, the insulated membrane features that 0.06 - 2.10 mols are contained 1 kinds or 2 kinds or more which are chosen from midst of the inorganic compound of Fe, Ni, Co, Cu, Sr and Mo vis-a-vis the phosphate and this phosphate 1 mol, as a metal element, the chrome the directivity electromagnetic steel sheet and its insulated membrane medicine which possess the insulated membrane which is not included.
