Simbi isina chinhu chigadzirwa chinoshamisa chinosanganisa kuumbwa kwesimbi neokisijeni, zvichiratidza kufambira mberi kunoshamisa mukushanda kwesimbi. Iyi alloy yakasarudzika, inoumbwa zvakanyanya nesimbi, chromium uye nickel, inozivikanwa nekupokana kwayo nekuora uye kusvibisa, zvichiita kuti ive sarudzo yepamusoro pane dzakasiyana siyana maindasitiri.
Nzira yekugadzira simbi isina tsvina inotanga nekunyatsosarudzwa kwezvinhu zvakasvibiswa. Iron ore inotorwa yobva yasanganiswa nechromium, iyo yakakosha pakuita ngura kwealloy. Kana yaiswa kuokisijeni, chromium inoumba chidimbu chekudzivirira chechromium oxide pamusoro pesimbi. Iyi inodzivirira layer inoshanda sechipingamupinyi kudzivirira kuwedzera oxidation, kuve nechokwadi chehupenyu hurefu hwechigadzirwa. Iyi synthesis pakati pesimbi neokisijeni ndiyo inomisa simbi isina tsvina kubva kune dzimwe simbi, ichiibvumira kuchengetedza kunaka kwayo uye kuvimbika kwechimiro kwenguva yakareba.
Munyika yekugadzira simbi, simbi isina tsvina yave yakakurumbira nekuda kwekusiyana-siyana uye kugara kwenguva refu. Inoshandiswa mumhando dzakasiyana-siyana dzekushandisa, kubva kumidziyo yekicheni uye tableware kune zvivakwa zvekuvaka uye zvigadzirwa zvekurapa. Simbi isina simbi inogona kuumbwa kuita akasiyana maumbirwo, zvichiita kuti ive chinhu chakanakira vanogadzira uye mainjiniya. Yayo yakapfava, yazvino kutaridzika inowedzerawo kubata kwekunaka kune chero chigadzirwa, ichiwedzera kuwedzera kukwezva kwayo.
Uyezve, kusimba kwesimbi isina tsvina hakugoni kufuratirwa. Kudzokororwa kwesimbi isina tsvina kune mukana wakakura sezvo inogona kushandiswa zvakare pasina kurasikirwa kwayo. Ichi chimiro chinoenderana nekukura kuri kudiwa kwezvinhu zvine hushamwari kwezvakatipoteredza mumusika wanhasi.
Muchidimbu, simbi isina tsvina inogadzirwa kuburikidza nekudyidzana kwesimbi neokisijeni uye ndiwo mufananidzo weunyanzvi hwekugadzira simbi. Hunhu hwayo hwakasiyana-siyana, kuita zvakasiyana-siyana uye kuenderera mberi kunoita kuti ive chigadzirwa chakakosha munyika yanhasi, ichigadzira nzira yezvigadziriso zvekugadzira uye mashandisirwo mumhando dzakasiyana dzemaindasitiri.
