Thaum ntau qib stainless hlau yuav txawv ntawm lawv cov metallurgic muaj pes tsawg leeg thiab alloying lossis raug txheej txheem, ib qho zoo uas lawv txhua tus sib koom yog txheej txheej passivation.
Cov txheej txheem ntawm chromium oxide no tshwm sim thaum lub npoo ntawm cov hlau raug cov pa oxygen.
Cov txheej yog nyias dhau los soj ntsuam ncaj qha thiab nyob rau hauv feem ntau cov xwm txheej tseem pom tseeb. Qhov no tso cai rau cov khoom tiav ntawm cov khoom siv stainless hlau los qhia thiab muab ntau yam kev xaiv los ntawm siab gloss rau matte.
Impervious rau dej, txheej passivation yog tus kheej tsim thiab pab tiv thaiv cov hlau. Txawm hais tias nws yuav tsis muaj xim nyob rau hauv qhov kub thiab txias, nws tseem ua haujlwm.
Txawm li cas los xij, stainless hlau tsis yog invincible. Nws tseem raug rau corrosion nyob rau hauv cov xwm txheej zoo.
