Birta aan daahin 304 waa heerka ugu isticmaalka badan ee birta ah.Waa bir aan lahayn chromium-nickel austenitic oo leh kaarboon yar oo xoogaa ka sarreeya chromium iyo nikkel marka loo eego nooca AISI 301 iyo 302. Fasalka 304 aad buu u dhuuban yahay marka uu jiro xaalad la daboolay.Waxay leedahay sifooyin heerkul sare oo wanaagsan iyo sidoo kale adayg wanaagsan heerkulka hooseeya.Waxay si fiican ugu habboon tahay alxanka iyo halka alaabta la dhammeeyey ay tahay inay iska caabiyaan noocyada daxalka ee aadka u daran.
Birta aan lahayn 304L waa bir kaarboon austenitic chromium nikkel ah oo aad u hooseeya oo leh daxal la mid ah nooca 304 laakiin leh iska caabin sare oo roobka carbide intergranular inta lagu jiro alxanka ama yaraynta walbahaarka.
