Insimbi eyi-Chromium-molybdenum cast isetshenziswa kakhulu emikhakheni yezimboni enezakhiwo ezisezingeni eliphakeme uma kuqhathaniswa. Ukwengezwa kwe-molybdenum ku-chromium steel kungakhuphula amandlaizinsimbi zensimbingaphandle kokuba nomthelela omkhulu ekuqineni komthelela wensimbi ekhonjiwe. Ngaphezu kwalokho, insimbi ye-chromium-molybdenum cast inokusebenza okuhle kakhulu kokushisa okuphezulu nokumelana nokukhuphuka. Ngemuva kokucisha nokushisa noma ukujwayela ukwelashwa kokushisa, insimbi ye-chromium-molybdenum cast ingathola izakhiwo ezinhle kakhulu zokusebenzisa.
I-Molybdenum ingathuthukisa ukuqina kwensimbi ekhonjiwe futhi inciphise ukufutheka kwensimbi. I-Chromium-molybdenum cast steel isetshenziselwaukulingwa kwezigaba ezinkulukanye nokubunjwa kwensimbi okudinga ukuqina okujulile.
