    摘要: A metallic comprising not more than 0.6% C, 12 to 19% Cr, 6 to 12% Ni, not more than 2% Mn, not more than 2% Mo, not more than 1% Nb and the balance being Fe and inevitable impurities, where

    Hirayama's equivalent H eq = [Ni %] + 1.05 [Mn %] + 0.65 [Cr %] + 0.35 [Si %] + 12.6 [C %] is 20 to 23%;
    Nickel equivalent Ni eq = [Ni %] + 30 [C %] + 0.5 [Mn %] is 9 to 12%, and
    Chromium equivalent Cr eq = [Cr %] + [Mo %] + 1.5 [Si %] + 0.5 [Nb %] is 16 to 19, wherein % is by weight, is made to have at least one ferromagnetized part having a magnetic flux density B 4000 of not less than 0.3T and at least one non-magnetized part having a relative magnetic permeability µ of not more than 1.2 at a temperature of not less than -40°C, as continuously and integrally formed, the non-magnetized part having crystal grain sizes of not more than 30 µm, by ferromagnetization and successive local non-magnetization of part or parts of the ferromagnetized member, and the thus obtained composite magnetic member is employed as a support member such as a sleeve in electromagnetic valves.
