Dusha sare:
Guud ahaan waxaa loo qaybin karaa 304 nal iftiin ah oo bir ah (oo loo tixraacayo: 304 wareeg ah, 304 ulo iftiin ah, ama 304 ahama bir bir ah oo dhalaalaya) iyo 304 bir madow wareeg ah (oo loo tixraacayo: 304 ulo madow, ama 304 birta aan lahayn ushii).
304 nalka iftiinka ah ee birta ah, waxaa loola jeedaa in dusha sare uu siman yahay, ka dib duubista, diirinta ama sawirida qabow ee habka nadiifinta;Caadi ahaan loo isticmaalo kiimikooyin kala duwan, cunto, dhar iyo mashiino kale iyo qalabyo iyo ujeeddooyin qurxineed oo kala duwan.Iyo waxa loogu yeero 304 birta madow wareega ama 304 birta birta ah (bar madow), waxaa loola jeedaa dusha sare ee qallafsanaanta madow, rogrogmida kulul, foornada ama habka annealing, ha la macaamilin dusha lakabka oksaydhka ee birta wareegsan. .
304 Birta Wareega ah ee Birta Ah Qiimaha 1kg Birta Daawaha
304/304L waa wax badan oo kala duwan, ujeedo guud oo ahama bir ah oo iska caabin wanaagsan u leh daxalka atmospheric, iyo kiimikooyin badan iyo cunto iyo cabitaan.Darajooyinkan waxaa lagu qeexi karaa xaaladda la tirtiray halkaasoo ay leeyihiin qaabayn aad u wanaagsan.
304/304L maaha bir birlab ah oo ku jira xaalada la jeexjeexay laakiin waxa laga yaabaa inay noqoto wax yar birlab (magnetic) natiijada shaqada qabow awgeed.
