Gabaɗaya, bakin karfe austenitic ba shi da magnetism.Amma martensite da ferrite suna da magnetism.Duk da haka, austenitic na iya zama Magnetic.Dalilan sune kamar haka:

Lokacin da aka ƙarfafa, ɓangaren maganadisu na iya barin saboda wasu dalilai masu narkewa;ɗauki 3-4 misali, saura 3 zuwa 8% al'ada ce ta al'ada, don haka austenite yakamata ya kasance cikin waɗanda ba magnetism ko raunin maganadisu ba.

Austenitic bakin karfe ba maganadisu bane, amma lokacin da sashi na γ ya haifar zuwa lokacin martensite, magnetism zai haifar bayan taurin sanyi.Za'a iya amfani da maganin zafi don kawar da wannan tsarin martensite da kuma mayar da rashin karfinsa.
