Phakathi kwezinhlobo ezahlukene zensimbi engagqwali, amamaki 304, 304L, no-304H avame ukusetshenziswa. Nakuba zingase zibukeke zifana, ibanga ngalinye linezakhiwo zalo ezihlukile kanye nezicelo zalo.
Ibanga304 insimbi engagqwaliiyona esetshenziswa kakhulu futhi eguquguqukayo ochungechungeni lwezinsimbi ezingenasici ezingama-300. Iqukethe 18-20% chromium kanye 8-10.5% nickel, kanye amanani amancane carbon, manganese, kanye ne-silicon. Leli banga linokumelana nokugqwala okuhle kakhulu kanye nokuhleleka okuhle. Kuvame ukusetshenziselwa izicelo ezifana nemishini yasekhishini, ukucubungula ukudla, kanye nokuhlobisa kwezakhiwo.
304L ipayipi yensimbi engagqwaliiwuhlobo lwamapayipi ensimbi ekhabhoni ephansi ebangeni lama-304, elinekhabhoni ephezulu engu-0.03%. Lokhu okuqukethwe kwekhabhoni ephansi kusiza ukunciphisa imvula ye-carbide ngesikhathi sokushisela, kuyenze ifanelekele izinhlelo zokushisela. Okuqukethwe kwekhabhoni ephansi futhi kunciphisa ubungozi bokuzwela, okuwukwakhiwa kwe-chromium carbides emingceleni yokusanhlamvu, okungaholela ekugqwaleni kwe-intergranular. I-304L ivamise ukusetshenziswa ezinhlelweni zokushisela, kanye nasezindaweni lapho ubungozi bokugqwala bukhathaza, njengokucubungula amakhemikhali kanye nemishini yokwenza imithi.
304H insimbi engagqwaliinguqulo yekhabhoni ephezulu yebanga lama-304, enekhabhoni esukela ku-0.04-0.10%. Okuqukethwe kwekhabhoni ephezulu kunikeza amandla angcono okushisa aphezulu kanye nokumelana nokukhasa. Lokhu kwenza i-304H ifanele ukusetshenziswa kwezinga lokushisa eliphezulu, njengemikhumbi yokucindezela, izishintshisi zokushisa, namabhoyili ezimboni. Kodwa-ke, okuqukethwe kwekhabhoni ephezulu kwenza i-304H ibe lula ukuzwela kanye nokugqwala kwe-intergranular, ikakhulukazi ezinhlelweni zokushisela.
Kafushane, umehluko omkhulu phakathi kwala mabanga okuqukethwe kwawo kwekhabhoni kanye nomthelela ekushiseleni nasekusetshenzisweni kwezinga lokushisa eliphezulu. Ibanga lama-304 liyinhloso esetshenziswa kakhulu futhi ejwayelekile, kanti i-304L iyinketho ekhethwayo yezinhlelo zokushisela kanye nezindawo lapho ukugqwala kuyinkinga. I-304H inokuqukethwe kwekhabhoni ephezulu futhi ifanele ukusetshenziswa kwezinga lokushisa eliphezulu, kodwa ukuba lula kwayo ukuzwela kanye nokugqwala kwe-intergranular kudinga ukucatshangelwa ngokucophelela. Lapho ukhetha phakathi kwala mabanga, kubalulekile ukucabangela izidingo ezithile zohlelo lokusebenza, okuhlanganisa indawo yokusebenza, izinga lokushisa, nezidingo zokushisela.
