2024 Umgangatho ophezulu ASTM 4140 Chrome Moly Hot Rolled Ingxubevange Steel Pipe
Inkcazelo emfutshane:
I-35CrMo inamandla okunyamezela okuphezulu kunye namandla okurhubuluza kubushushu obuphezulu, ifuthe elihle lokuqina kwiqondo lobushushu eliphantsi, ukuqina okuhle, akukho tyekelo lokutshisa, ukuguqulwa okuncinci kokucima, iplastiki eyamkelekileyo kumphetho obandayo kunye nokuqhubekeka okuphakathi.I-weldability engalunganga, ukufudumeza ngaphambi kwe-welding, unyango lwe-welding ye-welding kunye nokunciphisa uxinzelelo lusetyenziswa ngokubanzi emva kokucinywa kunye nokufudumala, kwaye kunokusetyenziswa emva kokucinywa komgangatho ophezulu kunye ophakathi kunye nokucima kunye nokushisa okuphantsi kunye nokuphakathi.
Iqumrhu lixhasa ifilosofi ethi "Yiba nguNombolo 1 kumgangatho ophezulu, usekelwe kumlinganiselo wetyala kunye nokuthembeka ekukhuleni", iya kuqhubeka ikhonza abathengi abatsha kunye nabatsha abavela ekhaya naphesheya ngokufudumeleyo ngo-2024 Umgangatho ophezulu we-ASTM 4140 Chrome Moly Hot. Umbhobho wentsimbi ye-Rolled Alloy, Kumgangatho ophezulu wokuwelda igesi kunye nezixhobo zokusika ezinikezelwe ngexesha nangeendleko ezifanelekileyo, unokuthembela kwigama leshishini.
Iqumrhu lixhasa ifilosofi ethi "Yiba nguNombolo 1 kumgangatho ophezulu, usekelwe kumlinganiselo wetyala kunye nokuthembeka ekukhuleni", iya kuqhubeka ikhonza abathengi abatsha kunye nabaphelelwe lixesha abasuka ekhaya naphesheya ngokufudumeleyo.I-China i-alloy yensimbi engenamthungo kunye nombhobho wentsimbi ye-alloy, Ukugcina isikhundla esiphambili kwishishini lethu, asize siyeke ukucela umngeni kumda kuzo zonke iinkalo zokudala izisombululo ezifanelekileyo.Ngendlela yakhe, sinokutyebisa indlela yethu yokuphila kwaye sikhuthaze indawo yokuhlala engcono kuluntu lwehlabathi.
I-34CrMo4 / 35CrMo isetyenziswa njengeendawo ezibalulekileyo zesakhiwo ezisebenza phantsi komthwalo ophezulu, njengendawo yokuhambisa izithuthi kunye neenjini;I-rotor, i-shaft engundoqo kunye ne-shaft yokuhambisa enomthwalo onzima we-turbo generator, icandelo elikhulu le-34CrMo4 lisetyenziselwa ukuvelisa i-forgings enamandla aphezulu kunye necandelo elikhulu lokucima kunye ne-tempering kune-35CrMo yentsimbi, njengegiya enkulu ye-locomotive traction, i-booster transmission gear, i-shaft yangasemva, intonga yokudibanisa kunye ne-spring clamp enomthwalo omkhulu.I-34CrMo4 ingasetyenziselwa ukudibanisa imibhobho ye-drill kunye nezixhobo zokuloba kwimithombo enzulu yeoli engaphantsi kwe-2000m.34CrMo4 I-Gas Cylinder Pipe, esetyenziswa kakhulu kwi-automobile gas cylinder installing, ukukhusela umlilo, iindawo zonyango, izixhobo zoshishino, njl.
Ixabiso elilinganayo lekhabhoni ye-CEQ ye-35CrMo yensimbi yi-0.72%.Ingabonwa ukuba i-weldability yesi sixhobo ihlwempuzekileyo, kwaye ukuthambekela kwayo okunzima kukhulu ngexesha le-welding.Ukuqhekeka okutshisayo kunye nokuthanda kokuqhekeka okubandayo kwendawo echaphazelekayo yobushushu ye-35CrMo ingxubevange yombhobho iya kuba nkulu.Ngokukodwa xa i-welding kwimo ecinyiweyo kunye nobushushu, ukuthambekela kokuqhekeka okubandayo kwendawo echaphazelekayo yobushushu kuya kubonakala kakhulu.Ngoko ke, ngesiseko sokukhetha izinto ezifanelekileyo ze-welding kunye neendlela ezifanelekileyo ze-welding, ubushushu obuphezulu be-welding preheating, phantsi kwemeko yemilinganiselo engqongqo yenkqubo kunye nolawulo olufanelekileyo lwe-interpass yokushisa, injongo ye-welding yemveliso inokufezekiswa.
