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; dauki 3-4 misali, 3 zuwa 8% saura al'amari ne na al'ada, don haka austenite ya kamata ya kasance cikin wadanda ba magnetism ko raunin maganadisu.

Austenitic bakin karfe ba maganadisu bane, amma lokacin da sashi na γ ya haifar da 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.
