Abstract
An austenized ferritic stainless steel includes a first region including a first soft magnetic layer composed of a ferrite phase, a first non-magnetic layer composed of an austenized phase in which the ferrite phase is austenized, and a first mixed layer in which the ferrite phase and the austenized phase are mixed, the first mixed layer being formed between the first soft magnetic layer and the first non-magnetic layer, and a second region including a second non-magnetic layer composed of the austenized phase, the second non-magnetic layer having a thickness greater than that of the first non-magnetic layer.
