Raws li cov hlau tsis muaj cov khoom tsis ruaj rau hauv peb lub neej, yuav ua li cas cais cov ntaub ntawv thiab cov khoom xyaw ntawm cov hlau tsis muaj hlau? Qhov qub tib xim, qhov txawv yog xees mais. Cov hlau tsis muaj hau cais ua ntau yam, hais txog cov hom tsis muaj cov hlau tsis huv, 201/304. 201 Cov kav hlau uas tsis muaj steel hlau, tseem hu ua hlau tsis muaj hlau, yog cov xim nickel thiab yog siv nrog tsev los yog kev ua lag luam decorations, xws li cov laib ntim hauv tsev / chav ua mov, thiab lwm yam.
304 stainless hlau yog dav siv nyob rau hauv peb lub Hoobkas. Nws yog siv nyob rau hauv lub Hoobkas khoom siv thiab lub tsev muag tshuaj cog. Nws yog zoo dua rau tawv tawv thiab compression dua li lwm tus steel. Tus nqi ntawm xee caj npab feem ntau tsis tsawg dua 8 tus npawb npas (nickel). Yuav ua li cas xaiv stainless hlau? Qhov txawv ntawm 201 thiab 304 yeeb nkab yog tias cov yeeb nkab ntawm xyoo 201 yog ci ntsa iab thiab ci iab, 304 yog lus tsis muaj dab tsi.
Yuav ua li cas kom paub qhov txawv hlau tsis muaj qab hau nrog los yog tsis muaj npib tsib xi?
Ua ntej: qhov qhia txog txoj kab sib txawv, feem ntau siv hauv steel, yog ib txoj hauv kev txheeb xyuas cov tshuaj muaj pes tsawg ntawm cov khoom (cov khoom ua ke) thiab cov ntsiab lus ntawm cov khoom, vim qhov txawv ntawm tus lej, cov duab, kev sib tw thiab xim ntawm ntau yam cov ntsiab lus thiab cov khoom siv thaum cov hniav sib tsoo yog zom hauv qab sib tsoo. Nickel cov ntsiab lus tseem yog qhov zoo tshaj plaws 8.0% -11.0%. Nickel cov ntsiab lus tseem ceeb, tab sis lwm yam xws li carbon, chromium, manganese, sulfur cov ntsiab lus tseem ceeb heev, yuav tsum them ntau xim.
