Simbi isina simbi chinhu chealloy chinoshandiswa zvakanyanya muhupenyu hwezuva nezuva uye kugadzirwa kwemaindasitiri, uye inofarirwa nekunaka kwayo kwekudzivirira kusimba uye kusimba. Pakati pemhando dzakawanda dzesimbi isina tsvina, 430 uye 439 imhando mbiri dzakajairika, asi pane zvimwe zvakakosha zvakasiyana pakati pavo.
Kubva pachemikari yakagadzirwa maonero
430 simbi isina tsvina ialloy ine 16-18% chromium uye isina nickel. Izvi zvinozvipa zvakanakisa kusada kusimba mune dzimwe nharaunda, kunyanya mune oxidizing midhiya. 439 simbi isina tsvina ialloy ine 17-19% chromium uye 2-3% nickel. Kuwedzerwa kwe nickel hakungonatsiridze kushora kwechinyorwa, asi zvakare kunowedzera kuoma kwayo uye processability.
Panyaya yezvimiro zvemuviri
430 simbi isina tsvina ndeye martensitic Stainless simbi ine kuoma kwakanyanya uye simba, asi yakaderera ductility uye kuoma. Izvi zvinoita kuti ive yakakodzera kune mamwe maapplication panodiwa simba repamusoro. 439 Stainless simbi imhando ye austenitic Stainless simbi, ine yakanaka ductility uye kuoma, inogona kushingirira deformation yakakura uye isiri nyore kuputsika.
Mukuwedzera, pane kusiyana pakati pezviviri mumunda wekushandiswa. Nekuda kwekuramba kwecorrosion uye kusimba kwakakwirira kwe430 simbi isina tsvina, inowanzoshandiswa mukugadzira mota inopopota masisitimu, michina yekuwachisa, kitchenware uye zvimwe zvinhu zvinoda kushingirira tembiricha yepamusoro uye nharaunda dzinoparadza. 439 simbi isina tsvina inoshandiswa zvakanyanya mu petrochemical, midziyo yekurapa, kugadzira chikafu nemimwe minda nekuda kwezvakanaka zvekugadzirisa zvivakwa uye kusakara.
Muchidimbu, 430 uye 439 simbi isina tsvina ine mimwe misiyano mukuumbwa kwemakemikari, zvimiro zvemuviri uye minda yekushandisa. Kunzwisisa kusiyana uku kunotibatsira kuti tisarudze zvirinani uye tishandise simbi isina tsvina kuti isangane nezvinodiwa zvenzvimbo dzakasiyana uye mashandisirwo.
