I-ASTM A335 ingxubevange yombhobho engenamthungo yentsimbi ephantsi ingxubevange yentsimbi engenamthungo
Inkcazelo emfutshane:
I-ASTM A335 ihlala ibizwa ngokuba ngumbhobho we-chrome moly ngenxa yekhemikhali equlathe i-Molybdenum (Mo) kunye neChromium (Cr).I-Molybdenum yongeza amandla entsimbi kunye neChromium (okanye i-chrome) yinto ebalulekileyo yensimbi engenasici.Ukubunjwa kwe-chrome moly alloy steel pipe yenza kube yinto efanelekileyo yokusetyenziswa kwizityalo zamandla, iindawo zokucoca, izityalo zepetroli zekhemikhali, kunye neenkonzo zentsimi yeoli apho ulwelo kunye neegesi zihanjiswa kumaqondo aphezulu kakhulu kunye noxinzelelo.
