Hauv kev txhim kho tseem ceeb,904L stainless hlau tuavtau tshwm sim los ua cov khoom siv nyiam hauv kev lag luam kub siab, hloov pauv txoj hauv kev uas ntau lub lag luam tswj hwm qhov chaw kub heev. Nrog nws qhov kev tiv thaiv kub zoo thiab kev tiv taus corrosion, 904L stainless hlau tau tsim nws tus kheej ua qhov kev xaiv mus-rau rau cov ntawv thov tseem ceeb uas qhov kub siab ua rau muaj kev cov nyom.
Qhov zoo ntawm 904L stainless hlau yog nws cov khoom sib xyaw thiab cov yam ntxwv tshwj xeeb. Cov hlau no muaj cov chromium ntau ntawm 23-28%, ua ke nrog cov pa roj carbon tsawg thiab cov nickel ntau dua (19-23%). Cov yam ntxwv no ua rau nws muaj peev xwm ua kom cov qauv ruaj khov thiab tiv taus oxidation txawm tias nyob rau hauv cov xwm txheej uas feem ntau yuav ua rau muaj kev puas tsuaj loj hauv lwm cov ntaub ntawv.
