SOFT MAGNETIC COMPONENT STEEL MATERIAL HAVING EXCELLENT PICKLING PROPERTIES, SOFT MAGNETIC COMPONENT HAVING EXCELLENT CORROSION RESISTANCE AND MAGNETIC PROPERTIES, AND PRODUCTION METHOD THEREFOR

摘要

Provided is a steel material for soft magnetic components, having excellent pickling properties and capable of achieving excellent magnetic properties and corrosion resistance in a final component. The steel material for soft magnetic components comprises, in % by mass, 0.001% - 0.025% C, more than 0% but less than 1.0% Si, 0.1% - 1.0% Mn, more than 0% but no more than 0.030% P,more than 0% but no more than 0.08% S, more than 0% but less than 0.5% Cr, more than 0% but no more than 0.010% Al, and more than 0% but no more than 0.01% N, with the remainder being iron and unavoidable impurities; and is characterized by having a rolled scale including 40 - 80 vol% FeO being formed on the steel material surface.
