316 stainless hlau muaj cov kua qaub thiab alkali zoo dua thiab kub tsis kam tshaj 304, thiab feem ntau yog siv hauv kev lag luam khoom noj thiab cov cuab yeej phais. Tsis tas li ntawd, 316 stainless hlau muaj qhov zoo tshaj plaws, uas yog, tsis muaj thermal expansion thiab contraction, uas yog ib qho tseem ceeb heev rau precision qhov chaw.
Cov ntsiab lus chromium ntawm 304 stainless hlau thiab 316 stainless hlau yog li 16-18%, tab sis qhov nruab nrab nickel ntsiab lus ntawm 304 stainless hlau yog 9%, thiab qhov nruab nrab nickel ntsiab lus ntawm 316 stainless hlau yog 12%.
Nickel nyob rau hauv cov ntaub ntawv hlau tuaj yeem txhim kho qhov kub thiab txias, cov khoom siv kho tshuab thiab oxidation tsis kam ntawm cov khoom. Yog li ntawd, cov ntsiab lus ntawm nickel nyob rau hauv cov khoom ncaj qha cuam tshuam rau tag nrho cov kev ua tau zoo ntawm cov khoom.
Nyob rau hauv peb lub neej niaj hnub, peb feem ntau muaj lub lauj kaub, tais, diav, phiab, duav, diav thiab thermos khob, thiab lwm yam. Cov khoom siv niaj hnub no feem ntau siv 304 stainless hlau. Feem ntau hais lus, 304 stainless hlau yog txaus rau peb lub neej txhua hnub. Vim tias 304 stainless hlau yog tus cwj pwm los ntawm acid thiab alkali tsis kam thiab kub tsis kam. Cov tais diav peb feem ntau siv yog corroded los ntawm cov kua qaub thiab alkali, yog li peb tsuas yog yuav tsum muaj peev xwm tiv taus acid thiab alkali.
Stainless hlau nqus plua plav tau siv dav hauv peb lub neej niaj hnub, tab sis tseem muaj ntau yam kev paub txog kev xaiv stainless hlau nqus tsev vacuum.
Piv txwv li, thaum peb yuav lub tshuab nqus tsev vacuum, peb tsuas yog saib cov lus" GB9684" ntawm pob lossis seb puas muaj"SUS304" ntawm lub khob. Peb yuav tsum tau yuav cov khoom kuaj stainless hlau.
Vim tias cov zaub mov qib 304 stainless hlau yuav tsum tau ua kom tau raws li cov qauv hnyav hlau nag lossis daus, thiab 304 stainless hlau zoo tib yam tsis tau ua tiav cov kev xeem no, yog li thaum koj yuav, koj yuav tsum ua tib zoo xyuas cov khoom ntawm lub pob.
