Abstract

The present invention is directed at a method of production grain oriented Fe-Si steel sheet presenting an induction value at 800A/m above 1.870 Tesla and a core power loss lower than 1.3 W kg at a specific magnetic induction of 1.7 Tesla (T). The steel chemical composition comprises, in weight percentage: 2.8 ≤ Si ≤ 4, 0.20 ≤ Cu ≤ 0.6, 0.05 ≤ Mn ≤ 0.4, 0.001 ≤ Al ≤ 0.04, 0.025 ≤ C ≤ 0.05, 0.005 ≤ N ≤ 0.02, 0.005 ≤ Sn ≤ 0.03, S ≤ 0.015 and optionally Ti, Nb, V or B in a cumulated amount below 0.02, the following relationships being respected : Mn/Sn ≤ 40, 2.0 ≤ C N ≤5.0, Al/N ≥ 1.20, and the balance being Fe and other inevitable impurities.
