Lub npe hu ua kev kho kom zoo tshaj plaws feem ntau yog hais txog kev kho mob chromium, yog siv los ntsuas cov roj sib txawv ntawm cov hlau tsis muaj zog, yog cov dej nag, nag cua, nag li nag lossis nag li txhais tau tias kev kuaj pom. Ntawm no yog cov lus qhia ntxaws ntxaws:
Cov kev kho kom zoo tsis yog qhov kev kho cua sov uas yuav tsum tau siv rau hauv cov txheej txheem tsim khoom ntawm 303 stainless hlau pas nrig lossis lawv cov khoom. Nws yog siv los ua cov txheej txheem rau kev kuaj cov intergranular corrosion tiv taus ntawm 304 stainless hlau pas nrig. Lub ntsej muag zoo yog qhov tseem ceeb kev kho mob uas ua rau cov hlau tsis muaj zog ntawm cov hlau tsis sib haum. Vim tias qhov kev kho kom zoo tuaj yeem ua rau cov carbide carbide hauv kev sib txuas lus nrawm dua rau qhov muaj peev xwm txhim kho ntawm cov hlau uas muaj peev xwm nrawm dua ntawm cov hlau uas tsis tshua muaj zog.
