摘要：
The present invention relates to a soft magnetic steel improved in electric resistance, coercive force, magnetic flux density, magnetic response, cold forgeability, machinability, and corrosion resistance, which is characterized by the composition containing by weight, 0.015% or lower C+N, 0.20% or lower Si, 0.20% or lower Mn, 7 to 13% Cr, 2 to 5% Al, and balance of Fe with impurities, which is applicable to core materials of electronic fuel injection systems, solenoid valves, electromagnetic sensors, etc.
