Muri rusange, icyuma kitagira imirasire cyangwa icyuma cya austenitic ntabwo gifite magnetism. Ariko martensite na ferrite bifite magnetism. Ariko, austenitic nayo ishobora kuba magnetism. Impamvu ni izi zikurikira:

Iyo ikomera, igice cya rukuruzi gishobora kuvaho bitewe n'impamvu runaka yo gushonga; fata urugero rwa 3-4, ibisigaye bya 3 kugeza kuri 8% ni ibintu bisanzwe, bityo austenite igomba kuba iy'idafite rukuruzi cyangwa rukuruzi idakomeye.

Icyuma cya Austenitic si magnetic, ariko iyo igice cya γ kigize martensite phase, magnetism izavuka nyuma yo gukonja. Gutunganya ubushyuhe bishobora gukoreshwa mu gukuraho iyi martensite no kugarura idafite magnetism.
