Abstract

A process for the production of grain oriented magnetic steel sheets having improved remagnetization losses consisting essentially of (in % by weight) more than 0.005% to 0.10% C, 2.5 to 6.5% Si, 0.03 to 0.15% Mn, 0.010 to 0.050% S, 0.010 to 0.035% Al, 0.0045 to 0.0120% N, and 0.020 to 0.300% Cu, and up to 0.15% Sn, the balance being iron and inevitable impurities. The process includes continuous casting or strip casting slabs with the above composition.
