Vim li cas stainless hlau kuj xeb? Thaum cov xim av xeb (spots) tshwm rau ntawm cov kav hlau stainless, tib neeg xav tsis thoob: "Stainless hlau tsis xeb, thiab yog tias nws xeb, nws tsis yog stainless hlau, thiab tej zaum yuav muaj teeb meem nrog cov hlau." Qhov tseeb, qhov no yog ib qho kev xav tsis zoo txog kev tsis nkag siab ntawm stainless hlau. Stainless hlau kuj yuav xeb nyob rau hauv tej yam kev mob.
Stainless hlau muaj peev xwm tiv taus atmospheric oxidation - uas yog, xeb kuj, thiab kuj muaj peev xwm corrode nyob rau hauv xov xwm uas muaj acids, alkalis, thiab ntsev - uas yog, corrosion kuj. Txawm li cas los xij, qhov loj ntawm nws lub peev xwm los tiv thaiv corrosion yog hloov nrog cov tshuaj muaj pes tsawg leeg ntawm cov hlau nws tus kheej, lub xeev kev tiv thaiv, kev siv cov xwm txheej thiab hom kev tshaj tawm ib puag ncig. Piv txwv li, 304 yeeb nkab fittings muaj peev xwm tiv thaiv corrosion zoo heev nyob rau hauv qhov chaw qhuav thiab huv si, tab sis yog tias nws tau txav mus rau thaj chaw ntug dej hiav txwv, nws yuav sai sai xeb hauv hiav txwv pos uas muaj ntsev ntau; thaum 316 yeeb nkab fittings qhia zoo. Yog li ntawd, nws tsis yog txhua yam ntawm stainless hlau uas tuaj yeem tiv taus corrosion thiab xeb hauv ib puag ncig.
