Abstract
Stainless steels are an important class of alloys, and are already used in a broad range of applications, especially used as electronic information materials. To take advantage of their magnetic characteristics, many fundamental magnetic problems involving stainless steels must be further studied. In this paper, magnetic measuring of ferrite stainless steels are conducted using the ring samples and bar samples in different magnetic fields, which are both frequently used in industry for quality control. From the magnetic parameters obtained from the major loops of both samples, such as Br, Hc, μ r , Js and H μmax , large differences were found, revealing that, in ferrite stainless steel two kinds of samples can get quite a different result. The reasons are discussed. Furthermore, the benefits of both kinds of samples are discussed in terms of sample dimensions, anisotropy, demagnetization field, and inclusions. Moreover, the typical magnetic data obtained from the major and minor hysteresis loops are also discussed.
