摘要：
There is provided a stator yoke capable of improving magnetic characteristics and a rust-proofing effect of a stator yoke produced by using a Fe-Cr type alloy. When a stator yoke is produced by using a Fe-Cr type alloy, its magnetic characteristics can be improved, but when press working is made to obtain a predetermined shape, the magnetic characteristics drop. Annealing is carried out so as to recover the magnetic characteristics. This annealing generates the property change of a surface layer and a rust-proofing effect lowers.
