NON-DIRECTIONAL ELECTROMAGNETIC STEEL PLATE WITH EXCELLENT MAGNETIC CHARACTERISTICS

摘要

A non-oriented electrical steel sheet having a high magnetic flux density and a low anisotropy contains C: not more than 0.01 mass%, Si: 1-4 mass%, Mn: 0.05-3 mass%, P: 0.03-0.2 mass%, S: not more than 0.01 mass%, Al: not more than 0.004 mass%, N: not more than 0.005 mass%, As: not more than 0.003 mass%, and preferably further contains one or two of Sb: 0.001-0.1 mass% and Sn: 0.001-0.1 mass% or further contains one or two of Ca: 0.001-0.005 mass% and Mg: 0.001-0.005 mass%.
