Chromium-molybdenum birta shubka ah ayaa si weyn loogu isticmaalaa beeraha warshadaha leh sifooyin farsamo oo aad u sarreeya. Ku darida molybdenum ee birta chromium waxay kordhin kartaa xooggashubista birtaiyada oo aan saameyn weyn ku yeelan saameynta adag ee birta shubka ah. Intaa waxaa dheer, chromium-molybdenum cast steel waxay leedahay wax qabad heerkul sare oo aad u wanaagsan iyo iska caabin gurguurta. Ka dib marka la demiyo oo la qaboojiyo ama caadiyeeyo daaweynta kulaylka, birta chromium-molybdenum ee kabka ah waxay heli kartaa sifooyin farsamo oo aad u fiican.
Molybdenum waxay wanaajin kartaa adkaanta birta shubka waxayna yaraynaysaa jajabnaanta xanaaqa ee birta shubka ah. Chromium-molybdenum birta shubka ah ayaa loo isticmaalaatuurista qaybo waaweyniyo biraha la shubo oo u baahan adkayn qoto dheer.
