| Abstract: | In order to meet the demand for new energy vehicles--electric vehicle （EV） and hybrid electric vehicle （HEV） motor for high performance non-oriented electrical steel. Non-oriented electrical steel featuring great strength and low core loss has been developed by Sumitomo Metal Industries Ltd.. The strengthening mechanism was mainly applied was dislocation strengthening. This paper introduces a the typical properties of developed steel of 0.35ram 690 and 780 MPa grades both in tensile strength and fatigue strength are superior to that of the 980-MPa grade dual-phase steel which costs could be minimized and have been widely applied in electric vehicle （EV） and hybrid electric vehicle （HEV） with high efficiency permanent magnet （IPM） motor core. |
