RAW MATERIAL POWDER FOR SINTERED SOFT MAGNETIC STAINLESS STEEL AND PRODUCTION METHOD FOR THE SINTERED SOFT MAGNETIC STAINLESS STEEL USING THE POWDER

摘要

PROBLEM TO BE SOLVED: To provide raw material powder as the raw material for sintered soft magnetic stainless steel which has improved compressive moldability, corrosion resistance and magnetic properties, and to produce sintered soft magnetic stainless steel which is more excellent than the conventional one. SOLUTION: In the raw material powder for sintered soft magnetic stainless steel, soft magnetic stainless steel fine powder which contains, by mass, 7 to 15% Cr and 1 to 4% Si and does not contain Al is granulated into the granulated powder having the average grain size of 10 to 150μm.
