Abstract: A silicon steel 100AW800DC, which is one of the iron core material of high performance electromagnetic switch, has been successfully developed by combining industrial production with laboratory annealing experiment. Its performance has reached the advanced level of electromagnetic switch iron core material. And the electromagnetic properties will be the best when the transverse thickness deviation is about 26 μm and the range of average grain size from 60 μm to 80 μm. Through simulated annealing experiment of production line, the properties of 100AW800DC with the lowest core loss P1.5/50 of  5.826 3 W/kg, magnetic induction intensity B2500 of 1.631 8 T, hardness HV5 of 159 and yield strength Rp0.2 of 324 MPa can be obtained in the condition of heating time 4 min44 s at 870 ℃.
