ABSTRACT:
Ferritic stainless steel that can be used for ferromagnetic parts, characterized in that it comprises in its composition by weight:C≦0.030%1.0%<Si≦3%0.1%<Mn≦0.5%10%≦Cr≦13%0%<Ni<1%0.03%<S<0.5%0%<P≦0.030%0.2%<Mo≦2%0%<Cu≦0.5%0%<N≦0.030%0%<Ti≦0.5%0%<Nb≦1%0%<Al≦100×10−4%30×10−4%<Ca≦100×10−4%50×10−4%<O≦150×10−4%the ratio of the calcium content to the oxygen content Ca/O being0.3≦Ca/O≦1,the balance being ion and the inevitable impurities from the smelting of the steel, and a process for manufacturing ferromagnetic parts.
