I-ASTM A335 ingxubevange yentsimbi yombhobho ongenamthungo

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, ii-refineries, izityalo zeekhemikhali zepetroli, kunye neenkonzo zentsimi yeoli apho ulwelo kunye neegesi zihanjiswa kumaqondo aphezulu kakhulu kunye noxinzelelo.
