SUS304 (SUS zvinoreva simbi isina tsvina yesimbi) simbi isina tsvina austenite inowanzonzi SS304 kana AISI 304 muchiJapan. Musiyano mukuru pakati pezvinhu zviviri izvi hausi chero zvimiro zvemuviri kana hunhu, asi nzira yavanotorwa nayo muUnited States neJapan.
Nekudaro, pane misiyano yemagetsi pakati pemasimbi maviri. Mune mumwe muenzaniso, SS304 samples dzakatorwa kubva kuUS masosi uye SUS304 samples dzakatorwa kubva kuJapan masosi akatumirwa kurabhoritari kunoongororwa.
SUS304 (JIS standard) ndeimwe yeanonyanya kushandiswa shanduro dzesimbi isina tsvina. Inoumbwa ne18% Cr (chromium) uye 8% Ni (nickel). Inogona kuramba ichichengetedza simba rayo uye kupisa kwekudzivirira pakupisa kwepamusoro uye kwakaderera. Iyo zvakare ine yakanaka weldability, mechanical zvivakwa, inotonhora workability uye corrosion resistance pakamuri tembiricha. SS304 (ANSI 304) ndiyo inonyanya kushandiswa simbi isina tsvina pakugadzira zvimwe zvinhu zvesimbi isina tsvina, uye inowanzotengwa pasi pekutonhora kana kuti annealing. Zvakafanana neSUS304, SS304 inewo 18% Cr uye 8% Ni, saka inonzi 18/8. SS304 ine yakanaka weldability, kupisa kwekudzivirira, corrosion kuramba, yakaderera tembiricha simba, workability, michina zvivakwa, kupisa kurapwa hakuna kuomeswa, kukotama, kutsika isothermal kushanda zvakanaka. SS304 inoshandiswa zvakanyanya mumaindasitiri mazhinji, kusanganisira chikafu, chekurapa uye chekushongedza basa. Kemikari yakagadzirwa yeSUS304 uye SS 304

Corrosion resistance ye304 Stainless simbi Sezvatinoziva tese, 304 Stainless simbi inoita zvakanaka munzvimbo dzakasiyana siyana dzemuchadenga uye corrosive media. Nekudaro, munzvimbo inodziya ye chloride, kana tembiricha ichipfuura 60 ° C, inowanzoitika kune gomba corrosion, crevice corrosion uye kusagadzikana ngura. Pane tembiricha yakadzikama, inonziwo inokwanisa kumira nemvura yekunwa ine inosvika 200 mg/l chloride.Hunhu hwenyama hweSUS304 uye SS304
Izvo zvinhu zviviri zviri pedyo zvakanyanya mune zvemuviri uye zvemakemikari zvinhu, saka zviri nyore kutaura kuti iwo akafanana zvinhu. Saizvozvo, musiyano mukuru pakati penyika mbiri idzi ndeyekumira pakati peUnited States neJapan. Izvi zvinoreva kuti kunze kwekunge mirau kana zvinodiwa zvakatsanangurwa nenyika kana mutengi, chinhu chimwe nechimwe chinogona kushandiswa neimwe nzira.
