SAE8620H Steel Round Bar /GB 20CrNiMo Steel bar
Iimbonakalo
Intsimbi ye-8620 ye-alloy yenziwe (ngokwehla komyalelo wepesenti) isinyithi, i-carbon, i-silicon, i-molybdenum, i-manganese, i-nickel, i-chromium, isulfure kunye ne-phosphorus.Ezi zinto zezithako kufuneka zibe ngaphakathi kweepesenti ezithile zobunzima ukwenza i-8620 alloy.Kunconywa ukuba insimbi iqiniswe yi-carburization elandelwa yioli, ngokuchasene namanzi, cima.Inoxinano olufanelekileyo lwentsimbi yealloys kwi-intshi engama-28 nge-intshi nganye, nangona amandla ayo aqinile - ubungakanani bobunzima obunokuthi bubambe ngaphambi kokuphulwa - buphantsi, kwi-536.4 Mpa.I-avareji yamandla e-tensile ye-alloys yensimbi yi-758 ukuya kwi-1882 Mpa.
Xa i-alloy ye-8620 ifakwe ngokufanelekileyo i-carburized - ishushu kwiqondo lokushisa elimiselweyo kwaye emva koko ibonakaliswe kwi-arhente equkethe i-carbon, inkqubo eyongeza i-carbon layer eyongezelelweyo ngaphandle kwentsimbi, ngaloo ndlela iyenza ibe yomelele - isetyenziselwa ukwenza umatshini onjalo. iindawo njengeegiya, ii-crankshafts, kunye namaringi egiya.I-Carburized 8620 alloy yomelele kwaye yomelele, yiyo loo nto ikhethwa kula malungu.
