摘要： A stainless steel plate is manufactured by performing temper rolling using a dull roller after the finish cold rolling and bright annealing. The stainless steel plate has an arithmetic mean roughness Ra of 0.2 to 1.2 μm in a direction perpendicular to the rolling direction of the steel plate surface. Furthermore, the stainless steel plate has a transfer ratio of 15 to 70% which is an area ratio of a portion onto which a dull pattern is transferred relative to the steel plate surface. In addition, the micro-pits being formed in the steel plate surface, having a depth of 0.5 μm or more, and having an opening area of 10 μm2 or more, have an existing density in the steel plate surface of 10.0 or less per 0.01 mm2, and an opening area ratio in the steel plate surface of 1.0% or less.

摘要： A Fe-Cr soft magnetic material has electric resistivity not less than 50 &mgr;&OHgr;·cm and a metallurgical structure occupied by a ferrite phase at a surface ratio of 95% or more. A number of fine precipitates of 1 &mgr;m or less in particle size is controlled at a ratio not more than 6×105/mm2. The Fe-Cr alloy has the composition (expressed in mass or weight %) of C up to 0.05%, N up to 0.05%, Si up to 3.0%, Mn up to 1.0%, P up to 0.04%, S up to 1.0%, 5.0-20.0% Cr, Al up to 4.0%, 0-3% Mo, 0-0.5% Ti and the balance being essentially Fe under the conditions of (1) and (2). The Fe-Cr soft magnetic material is useful as a core, a yoke or the like installed in various types of magnetic sensors such as electric power steering, fuel injection systems for vehicles and A.C. magnetic circuits of solenoid valves, due to production of high magnetic induction in a high-frequency low-magnetic field: 4.3×%Cr+19.1×%Si+15.1×%Al+2.5×%Mo≧40.2 (1) 64×%Si+35×%Cr+480×%Ti+25×%Mo+490×%Al≧221×%C+247×%N+40×%Mn+80×%Ni+460 (2).
