Alloy Steel Dhuumahawaxaa loo isticmaalaa codsiyada u baahan guryaha iska caabinta daxalka oo dhexdhexaad ah oo leh adkeysi wanaagsan iyo kharash dhaqaale.... Waxaa jira laba qaybood oo kala ahbiraha daawaha ah- sarealloysoo hooseeyabiraha daawaha ah.
AdhamaadTuubooyinka daawaha hooseWalxaha waxaa badanaa loogu yeeraa walxaha chrome moly sababtoo ah qurxinta kiimikada ee Molybdenum (Mo) iyo Chromium (Cr).Chromium waxay kordhisaa adkaanta iyo xoogga oo kaliya waxa ay yaraynaysaa bartinimada.Molybdenum waxay wanaajisaa xoogga xajinta iyo gaar ahaan caabbinta kulaylka.
