I-304 insimbi engagqwali iyinsimbi engagqwali ye-austenitic futhi empeleni ingumkhiqizo ongewona uzibuthe. Kodwa-ke, ekukhiqizeni nasekusetshenzisweni kwangempela, kungase kutholakale ukuthi i-304 insimbi engagqwali ine-magnetism ethile ebuthakathaka. Lokhu kubangelwa ikakhulukazi izici ezilandelayo:

1. Ukuguqulwa kwesigaba ngesikhathi sokucubungula nokwakhiwa: Ngesikhathi sokucutshungulwa kanye nenqubo yokwenza insimbi engagqwali engu-304, ingxenye yesakhiwo se-austenite ingase iguquke ibe isakhiwo se-martensite. I-Martensite iyisakhiwo samagnetic, esizobangela ukubonakala kwensimbi engagqwali engu-304. Uzibuthe obuthakathaka.
2. Ithonya lezinto phakathi nenqubo yokuncibilikisa: Phakathi nenqubo yokuncibilikisa, ngenxa yethonya lezinto zemvelo nokulawulwa kwezinga lokushisa eliqinile lesisombululo, ezinye izakhi ze-martensite zingase zixutshwe zibe yinsimbi engagqwali ye-austenitic, okuholela kumagnetism ebuthaka.
3. Ukuguquguquka kokusebenza okubandayo: Phakathi nenqubo yokusebenza okubandayo kwemishini, insimbi engagqwali engu-304 izothuthukisa kancane kancane izinga elithile likazibuthe ngenxa yokugoba, ukuguquguquka, nokunwebeka okuphindaphindiwe kanye nokucaba.

Nakuba insimbi engagqwali engu-304 inozibuthe othile obuthakathaka, lokhu akuthinti izici zayo eziyinhloko njengensimbi engagqwali ye-austenitic, njengokumelana nokugqwala, ukusebenza kokucubungula, njll. Uma kudingekile ukuqeda amandla kazibuthe ku-304 insimbi engagqwali, ingatholakala ngokusebenzisa izinga lokushisa eliphezulu lokwelapha isixazululo.
