Cov yeeb nkab steel hlau tsis yooj yim rau xeb thiab muaj kev sib raug zoo nrog kev sib xyaw ntawm cov hlau tsis huv. Ntxiv rau cov hlau, stainless hlau muaj chromium, npib tsib xee, txhuas, silicon, thiab lwm yam. Cov ntsiab lus chromium ntawm cov hlau stainless feem ntau tsis tsawg dua 12%, thiab tseem mus txog 18%. Tom qab ntxiv chromium thiab lwm yam ntsiab lus rau hlau, cov khoom ntawm cov hlau tuaj yeem hloov tau. Piv txwv, cov qauv tsim qauv ntawm cov hlau tsis sib luag, thiab ib daim duab tiv thaiv oxide tiv thaiv ntau dua yog tsim los ntawm cov nplaim ntawm cov hlau, yog li txhim kho kev txhim kho corrosion ntawm stainless hlau. Yog li, cov hlau tsis xeb tuaj yeem tiv taus qhov corrosion ntawm hluav taws, dej, acid, alkali thiab ntau yam kev daws teeb meem, thiab tsis xeb. Cov kws tshawb fawb tau pom tias kev sib txawv hauv cov qauv hauv cov hlau ntau dua, cuam tshuam ntau yam ntawm cov khoom sib txawv, qhov nyuaj nyuaj ntxiv yog qhov tshuaj tiv thaiv tsis muaj zog. Ib qho ntxiv, ib zaj yeeb yaj kiab tiv thaiv oxide txuas rau sab, uas zoo li muab tso rau cov cuab yeej hlau. Nws yuav tsis xeb yooj yim.
