SOFT MAGNETIC STEEL MATERIAL SUPERIOR IN MACHINABILITY AND MAGNETIC PROPERTY, SOFT MAGNETIC STEEL PART SUPERIOR IN MAGNETIC PROPERTY, AND METHOD FOR MANUFACTURING SOFT MAGNETIC STEEL PARTS

摘要

PROBLEM TO BE SOLVED: To provide a soft magnetic steel material which has superior machinability, is machined at a high yield even when formed into steel parts having a complicated shape, and secures superior magnetic properties.

SOLUTION: The soft magnetic steel product is substantially the single phase structure of ferrite, in which composite precipitates consisting of MgO-Al2O3-based double oxide surrounded by sulfides are dispersed in the ferrite structure.
