Austenitic stainless steel is classified as a nonmagnetic material. However application of stress transforms the plastic part of it into a martensitic crystal structure and it takes on magnetization. Strain evaluation can be performed by measuring the leakage magnetic flux from the remanent magnetization after applying stress to austenitic stainless steels. This paper presents the measurement to make clear the distributions of the leakage magnetic flux after applying strain into austenitic stainless steels by magnetic sensors.
