304 Stainless simbi pombi ine zvizere zvirevo
Nzira dzakajairwa dzekumaka pamusika dzinosanganisira 06cr19ni10 uye SUS304, iyo 06cr19ni10 inowanzoreva kugadzirwa kwenyika, 304 kazhinji inoreva ASTM yakajairwa kugadzirwa, uye SUS 304 inoreva kugadzirwa kweJapan.
304 isimbi yepasirese isina tsvina, iyo inoshandiswa zvakanyanya kugadzira midziyo uye zvikamu zvinoda kuita kwakanaka kuzere (corrosion resistance uye formability). Kuti uchengetedze kusimba kwemararamiro ekuramba kwesimbi isina tsvina, simbi yacho inofanira kunge iine zvinopfuura 18% chromium uye kupfuura 8% nickel. 304 Stainless simbi imhando yesimbi isina tsvina inogadzirwa zvinoenderana neAmerican ASTM zviyero.

Kune 304 simbi isina tsvina, iyo Ni element mukuumbwa kwayo yakakosha zvikuru, iyo inosarudza zvakananga kupikisa kwekuora uye kukosha kwe304 simbi isina tsvina.
Zvinhu zvakanyanya kukosha mu304 ndiNi uye Cr, asi hazvigumiri pazvinhu zviviri izvi. Izvo zvinodiwa chaizvo zvinotsanangurwa muyero yechigadzirwa. Zvinoenderana nemutongo wakajairika muindastiri, 304 simbi isina tsvina inogona kutariswa chero bedzi iyo Ni content yakakura kupfuura 8% uye iyo Cr yemukati yakakura kupfuura 18%. Ichi ndicho chikonzero nei rudzi urwu rwesimbi isina tsvina ichinzi 18/8 simbi isina tsvina muindastiri. Muchokwadi, iwo akakodzera zvigadzirwa zviyero zvine akajeka gadziriso pa304, uye izvi zvigadzirwa zviyero zvine mimwe misiyano yemhando dzakasiyana dzesimbi isina tsvina. Heano mamwe akajairika zvigadzirwa zviyero uye bvunzo.
Kuti uone kana chinhu chiri 304 simbi isina tsvina, inofanirwa kusangana nezvinodiwa zvechimwe nechimwe chinhu muyero yechigadzirwa. Chero bedzi munhu asingasviki zvinodiwa, haigoni kunzi 304 simbi isina tsvina.

Miyero mina iri pamusoro apa ingori miyero mishoma yakajairika. Asi izvo, zvinopfuura aya zviyero zvinotaurwa muASTM neJIS. Asi izvo, chiyero chega chega chine zvinodiwa zvakasiyana zve304, saka kana iwe uchida kuona kuti chinhu chiri 304, kutaura chaiko kunofanirwa kunge kuri kuzadzisa izvo 304 zvinodiwa muchiyero chechigadzirwa.
