Influence of the silicon content on the maximum magnetic flux density was studied on the sintered Fe-18Cr-2Mo alloy at applied magnetic field in three Oersted. The highest maximum magnetic flux densities in DC and AC magnetic field were attained at the content of two-percent silicon. The lower magnetic properties was observed for the three-percent silicon or more. The sintered density and the DC maximum magnetic flux density consequently were improved with the rise of sintering temperature. On the other hand the AC maximum magnetic flux density indicated the change of a decrease after an increase. An excess sintering temperature rather causes a lowering of AC maximum magnetic flux density. An increase of the resistivity contributes to an improvement of AC maximum magnetic flux density on the whole, but for the lower sintered density, tends to cause the deteriorating of AC maximum magnetic flux density.
