Cikakken sunan 304 bakin karfe bututu ne SUS304 bakin karfe bututu.

SUS304 bakin karfe bututu ne bakin karfe bututu na Amurka iri, kuma na cikin gida iri ne daidai da 0Cr19Ni9 bakin karfe bututu, wanda yawanci maye gurbinsu da 0Cr18Ni9.

Tsarin rigakafin tsatsa na bakin karfe shine cewa abubuwan gami suna samar da fim mai yawa oxide don ware lambar iskar oxygen da hana ƙarin iskar shaka. Don haka bakin karfe ba "bakin karfe".

Abubuwan 304 na iya yin tsatsa saboda dalilai masu zuwa:

1. Chloride ion yana samuwa a cikin yanayin sabis.

Chloride ions sun kasance a ko'ina, kamar gishiri, gumi, ruwan teku, iska, ƙasa da sauransu. Bakin karfe yana lalata da sauri a gaban ions na chloride, har ma fiye da ƙananan ƙananan ƙarfe na carbon.

Sabili da haka, akwai buƙatu don yanayin sabis na bakin karfe, kuma yana buƙatar goge akai-akai don cire ƙura da kiyaye tsabta da bushewa.

316 da 317 bakin karfe (duba masu zuwa don kaddarorin bakin karfe 317) molybdenum ne dauke da bakin karfe. Abubuwan da ke cikin molybdenum na bakin karfe 317 ya dan yi sama da na bakin karfe 316. Saboda molybdenum a cikin karfe, gaba ɗaya aikin wannan ƙarfe ya fi 310 da 304 bakin karfe. A karkashin yanayin zafi mai zafi, 316 bakin karfe yana da aikace-aikace masu yawa lokacin da maida hankali na sulfuric acid ya kasance ƙasa da 15% kuma sama da 85%. 316 bakin karfe kuma yana da kyawawan kaddarorin lalata chloride, don haka yawanci ana amfani dashi a cikin yanayin ruwa.

Tare da ci gaban tattalin arzikin zamantakewa, aikace-aikacen bututun bakin karfe ya kasance mafi shahara. Zai kawo sabbin canje-canje a fagage daban-daban.
