Tsis txhob ntseeg cov cim ntawm cov khoom lag luam stainless hlau yog tias koj tsis tuaj yeem qhia nrog qhov muag liab qab. Ntau 201 luam tawm nrog 304. Yog tias koj tuaj yeem siv cov hlau nplaum kom paub qhov txawv ntawm 201 thiab 304, cov hlau nplaum tuaj yeem ua rau hauv lub khob thermos. Tom qab ua haujlwm txias, 201 yog sib nqus tom qab ua haujlwm txias, uas tsis muaj zog dua li cov hlau zoo tib yam. Tab sis nws kuj tseem pom tseeb tias lub zog nqus 304 tsis yog hlau nplaum, lossis heev.
Seb tusthermos khobtuaj yeem kuaj nrog dej ntsev yog 304304. Nws yog cov khoom siv stainless hlau ntau yam uas muaj zog tiv thaiv xeb kev ua tau zoo thiab kub kub tiv taus mus txog 1000-1200 degrees. Nws muaj zoo heev stainless corrosion kuj thiab zoo kuj rau intergranular corrosion. Cov txheej txheem yog alloy cov ntsiab lus ua yeeb yaj kiab oxygen sib cuag thiab tiv thaiv cov roj oxidation txuas ntxiv, uas zoo nkauj.
Cov dej ntsev noj tau corrosive rau qee yam. Yog tias nws yog 202 stainless hlau yeeb nkab, nws yuav xeb hauv 24 teev yog tias nws muab tso rau hauv dej ntsev. Txawm li cas los xij, qhov tsim nyog 304 stainless hlau tsis muaj hlau, yog li nws yuav tsis xeb Tab sis nyob rau lub sijhawm luv luv, tsis muaj hnub qub hloov.
1. Kev txheeb xyuas yooj yim ntawm thermal rwb thaiv tsev kev ua tau zoo ntawm stainless hlau thermos khob. Qhov qis ntawm lub khob lub cev heats li, qhia tias cov khoom tau poob nws lub tshuab nqus tsev thiab tsis tuaj yeem ua tiav cov txiaj ntsig zoo thaum tshav kub kub.
Stainless hlau dej khob tsis tuaj yeem kuaj rau 304 cov khoom siv nrog dej ntsev. Txawm hais tias cov tshuaj chloride ions muaj cov nyhuv corrosive ntawm stainless hlau 304, nws yog qhov nyuaj dua rau kev cia siab rau cov dej ntsev, thiab kev tshuaj xyuas qhov muag yog qhov nyuaj heev.
