I-20CrNiMo ekuqaleni yayiyinombolo yensimbi 8620 kwi-American AISI kunye nemigangatho ye-SAE.Ukusebenza kobunzima kufana nentsimbi ye-20CrNi.Nangona umxholo we-Ni kwintsimbi isiqingatha sentsimbi ye-20CrNi, ngenxa yokongezwa kwexabiso elincinci le-Mo element, inxalenye ephezulu ye-austenite isothermal ijika yenguqu ihamba ngasekunene;kwaye ngenxa yokonyuka okufanelekileyo kumxholo we-Mn, ukuqina kwale ntsimbi kusekuhle kakhulu, kwaye amandla Ikwaphezulu kunentsimbi ye-20CrNi, kwaye inokubuyisela intsimbi ye-12CrNi3 ukuvelisa iinxalenye ze-carburized kunye ne-cyanide ezifuna ukusebenza okuphezulu okungundoqo.I-20CrNiMo inokumelana nobushushu obuthile ukongeza kwiipropati ezilungileyo ezibanzi kuba iqulethe i-molybdenum.
1. Kwishishini lokuvelisa, lihlala lisetyenziselwa ukwenza iinxalenye eziphantsi komthwalo ophezulu, uxinzelelo oluphezulu, kunye nokugqoka okuphezulu, njengeegiya, i-shafts, ii-bearings, njl. ubomi benkonzo ixesha elide kwiindawo zokusebenza ezinzima.Ukongeza, ikwanazo ukumelana nokudinwa okugqwesileyo kunye nokumelana nokugqwala, okunokuthi kuxhathise ngokufanelekileyo ukukhukuliseka kwendalo yangaphandle kunye nokuqinisekisa ukusebenza okuzinzileyo kwezixhobo.
2. Kwintsimi yokwakha, le ntsimbi isetyenziswa ngokubanzi ekwakhiweni kwezakhiwo ezinkulu ezifana namabhuloho kunye nezakhiwo eziphakamileyo ngenxa yamandla ayo aphezulu kunye ne-ductility enhle.Kwezi zakhiwo, ziyakwazi ukumelana noxinzelelo olukhulu kunye noxinzelelo, ziqinisekisa ukhuseleko kunye nokuzinza kwesakhiwo.
3. Ukongezelela, ngokuphuculwa kokuqwashisa ngokusingqongileyo, izicelo kwintsimi yokukhusela indalo ziba zibanzi ngakumbi.Ngokomzekelo, kwiimoto zamandla amatsha, zingasetyenziselwa ukuvelisa amacandelo abalulekileyo anjengeemoto kunye nezinciphisi, ezinegalelo ekuhambeni okuluhlaza.Ikwadlala indima ebalulekileyo kwizixhobo zokukhusela indalo ezifana nokucocwa kwamanzi amdaka kunye nokunyangwa kwegesi yenkunkuma, ukubonelela ngenkxaso eqinile yokuphucula umgangatho wokusingqongileyo.
1. Amacandelo abalulekileyo olwakhiwo, afana nezixhobo zokumisa inqwelomoya, iitanki kunye nezixhobo zesithuthi esixhotyisiweyo.
2. Izibophelelo eziphezulu kunye nezixhumi.
3. Iigiya eziphezulu zomthwalo kunye neebheringi.
Ukucima i-850ºC, i-oyile ebandayo;Ubushushu be-200ºC, ukupholisa umoya.
Ukuhanjiswa kunyango lobushushu (i-normalizing, annealing okanye iqondo lokushisa eliphezulu) okanye akukho meko yonyango lokushisa, imeko yokunikezelwa iya kuboniswa kwisivumelwano.
Ukuxhaswa liqela eliphuhliswe kakhulu kunye neqela leengcali, sinokubonelela ngenkxaso yobugcisa ekuthengisweni kwangaphambili kunye nenkonzo yasemva kokuthengisa.
