304 simbi isimbi yakajairika, inozivikanwawo se18/8 simbi isina tsvina muindastiri.Kuramba kwayo kwemarara kuri nani kupfuura 430 simbi isina tsvina, asi mutengo wakachipa kupfuura 316 simbi isina tsvina, saka inoshandiswa zvakanyanya muhupenyu, senge: imwe yepamusoro-giredhi Stainless simbi tableware, kunze Stainless simbi simbi, etc. Kunyange zvazvo 304 simbi iri yakajairika muChina, zita rekuti "304 simbi" rinobva kuUnited States.Vanhu vazhinji vanofunga kuti 304 simbi izita remuenzaniso muJapan, asi kunyatsotaura, zita repamutemo re304 simbi muJapan ndi "SUS304".304 simbi imhando yepasi rose simbi isina tsvina, iyo inoshandiswa zvakanyanya mukugadzirwa kwemidziyo uye zvikamu zvinoda kuita kwakanaka kwakazara (kupokana uye kuumbwa).Kuti uchengetedze kusimba kwekuora kunowanikwa musimbi isina tsvina, simbi yacho inofanirwa kunge iine zvinopfuura 16% chromium uye zvinopfuura 8% nickel yemukati.304 Stainless simbi imhando yesimbi isina tsvina inogadzirwa zvinoenderana neAmerican ASTM standard.304 yakaenzana ne0Cr18Ni9 simbi isina tsvina munyika yedu.
