Yog lawm, cov pa roj carbon steel muaj qhov cuam tshuam rau xeb yog tias nws tsis muaj kev tiv thaiv zoo lossis khaws cia. Kev xeb yog qhov tshwm sim ntawm oxidation ntawm hlau, thiab carbon steel, uas feem ntau yog tsim los ntawm hlau thiab carbon, tuaj yeem corrode thaum raug dej thiab oxygen. Thaum cov dej noo nkag mus rau hauv qhov chaw ntawm carbon steel thiab reacts nrog hlau, nws tsim hlau oxide, feem ntau hu ua xeb. Txawm li cas los xij, tus nqi ntawm xeb hauv carbon steel tuaj yeem sib txawv nyob ntawm ntau yam xws li cov ntsiab lus tshwj xeeb ntawm cov hlau, ib puag ncig, thiab muaj cov txheej txheem tiv thaiv lossis kev kho mob. Cov pa roj carbon hlau tuaj yeem ua rau xeb ntau dua piv rau cov hlau tsis muaj steel lossis lwm cov hlau tsis muaj corrosion-resistant. Txhawm rau tiv thaiv lossis txo qis kev xeb, cov pa roj carbon steel tuaj yeem tiv thaiv los ntawm ntau txoj hauv kev, suav nrog kev siv cov txheej txheem tiv thaiv xws li xim lossis zinc plating, siv cov hlau tsis muaj corrosion, thiab siv cov kev tu kom zoo. Kev tu, kom qhuav, thiab siv cov txheej txheem tiv thaiv los yog inhibitors tuaj yeem pab tiv thaiv lossis ua kom qeeb ntawm cov xeb ntawm cov pa roj carbon steel. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias txawm tias muaj kev tiv thaiv kev tiv thaiv, cov pa roj carbon steel tseem tuaj yeem ua rau xeb thaum lub sijhawm, tshwj xeeb tshaj yog tias cov txheej tiv thaiv raug puas los yog cov hlau raug cuam tshuam rau qhov hnyav lossis corrosive ib puag ncig.
