Title: NON-ORIENTED ELECTROMAGNETIC STEEL SHEET HAVING EXCELLENT RECYCLABILITY
Abstract:
A non-oriented electromagnetic steel sheet which has a component composition that contains 0.0050 mass% or less of C, 1.0-5.0 mass% of Si, 0.03-3.0 mass% of Mn, 0.2 mass% or less of P, 0.005 mass% or less of S, 0.05 mass% or less of Al, 0.0050 mass% or less of N, 0.010 mass% or less of O, 0.0030 mass% or less of Ti, 0.0030 mass% or less of Nb and 0.0005-0.0050 mass% of B, with the balance made up of Fe and unavoidable impurities. This non-oriented electromagnetic steel sheet has not only excellent recyclability but also excellent iron loss characteristics after strain relieving annealing.
