Hauv kev txhim kho tseem ceeb,904L stainless hlau tuavtau tshwm sim raws li cov khoom nyiam nyob rau hauv high-temperature industries, revolutionizing txoj kev ntau sectors lis huab cua sov puag ncig. Nrog rau nws qhov tshwj xeeb kub tsis kam thiab corrosion kuj, 904L stainless hlau tau tsim nws tus kheej ua qhov kev xaiv mus rau cov ntawv thov tseem ceeb uas qhov kub siab ua rau muaj kev sib tw.
Qhov kev thov rov hais dua ntawm 904L stainless hlau nyob hauv nws qhov tshwj xeeb muaj pes tsawg leeg thiab cov khoom. Cov hlau no muaj cov ntsiab lus siab chromium ntawm 23-28%, ua ke nrog cov pa roj carbon tsawg thiab cov ntsiab lus ntau dua nickel (19-23%). Cov cwj pwm no ua rau nws muaj peev xwm ua kom muaj kev ncaj ncees thiab tiv thaiv oxidation txawm nyob rau hauv cov xwm txheej uas ib txwm ua rau muaj kev puas tsuaj loj hauv lwm cov ntaub ntawv.
