304 stainless hlau yeeb nkab nrog tiav specifications
Cov txheej txheem kev cim ntau hauv kev ua lag luam suav nrog 06cr19ni10 thiab SUS304, ntawm qhov uas 06cr19ni10 feem ntau yog hais txog lub teb chaws tus qauv tsim, 304 feem ntau yog hais txog ASTM tus qauv tsim, thiab SUS 304 yog hais txog kev tsim khoom hauv Japanese.
304 yog ib qho universal stainless hlau, uas yog dav siv los ua cov cuab yeej thiab cov khoom uas xav tau kev ua haujlwm zoo (corrosion resistance and formability). Yuav kom tswj tau qhov kev tiv thaiv corrosion ntawm cov hlau tsis muaj steel, cov hlau yuav tsum muaj ntau tshaj 18% chromium thiab ntau tshaj 8% npib tsib xee. 304 stainless hlau yog ib hom ntawm stainless hlau ua raws li American ASTM cov qauv.

Rau 304 stainless hlau, Ni lub hauv paus hauv nws cov ntsiab lus tseem ceeb heev, uas ncaj qha txiav txim siab corrosion thiab tus nqi ntawm 304 stainless hlau.
Cov ntsiab lus tseem ceeb tshaj plaws hauv 304 yog Ni thiab Cr, tab sis lawv tsis txwv rau ob lub ntsiab lus no. Cov kev cai tshwj xeeb tau teev nyob rau hauv cov qauv khoom. Raws li kev txiav txim siab hauv kev lag luam, 304 stainless hlau tuaj yeem txiav txim siab ntev npaum li cov ntsiab lus Ni siab dua 8% thiab cov ntsiab lus Cr ntau dua 18%. Qhov no yog vim li cas cov hlau tsis zoo no hu ua 18/8 stainless hlau hauv kev lag luam. Qhov tseeb, cov qauv khoom lag luam muaj cov kev cai meej heev ntawm 304, thiab cov qauv khoom no muaj qee qhov sib txawv rau cov duab sib txawv ntawm stainless hlau. Nov yog qee cov qauv khoom siv thiab kev sim.
Txhawm rau txiav txim siab seb cov khoom puas yog 304 stainless hlau, nws yuav tsum ua kom tau raws li qhov yuav tsum tau muaj ntawm txhua lub hauv paus khoom. Tsuav yog ib qho tsis tau raws li qhov yuav tsum tau ua, nws tsis tuaj yeem hu ua 304 stainless hlau.

Plaub tus qauv saum toj no tsuas yog ob peb tus qauv xwb. Qhov tseeb, ntau tshaj li cov qauv no tau hais hauv ASTM thiab JIS. Qhov tseeb, txhua tus qauv muaj cov kev cai sib txawv rau 304, yog li yog tias koj xav txiav txim siab seb cov khoom puas yog 304, qhov kev qhia tseeb yuav tsum yog seb nws ua tau raws li 304 cov kev cai hauv cov qauv khoom.
