Vim li cas cov yeeb nkab steel hlau tsis txuas tsis yooj yim rau xeb
1. Vim tias tom qab cov hlau ua tiav, nws yuav tsis xeb nrog oxygen thiab dej, yog li nws tsis yooj yim rau xeb.
2. Hlau chromium ntxiv rau carbon hlau, thiab cov ntsiab lus tsis qis, txog 12%. Tom qab sib tiv tauj nrog huab cua, chromium yuav hnov mob nrog oxygen los ua zaj duab xis passivation ntom rau saum npoo ntawm cov pa roj carbon hlau, uas tuaj yeem tiv thaiv tau kev tiv thaiv tas li ntawm cov yeeb nkab tsis xeb hlau.
3. Qhov saum npoo ntawm cov yeeb nkab steel hlau muaj ib zaj duab xis passivation, uas yog super nyias, tab sis nws tuaj yeem pom cov lus tshaj tawm ntawm cov hlau saum npoo thiab muaj cov cim tshwj xeeb saum npoo, yog li nws yuav tsis xeb.
Cov yeeb nkab steel hlau muaj cov yam ntxwv ntawm kev ntseeg tau thiab muaj kev sib txuas zoo, kev tsim kho yooj yim thiab ceev, tsim nyog rau cov kab teeb tsa, kev hloov kho-tsis hloov kho tshiab, thiab kev lag luam zoo dua. Raws li txoj kev xav, cov yeeb nkab steel hlau txaws yuav tsis xeb, tab sis qhov tseeb, ntau qhov chaw nyob muaj ntau qib ntawm kev ziab thiab ntub. Cov neeg kawm ntawv ntawm corrosion yog qhov qub.
