2024 Zoo siab ASTM 4140 Chrome Moly Kub Rolled Alloy Steel Yeeb Nkab
Lus piav qhia luv luv:
35CrMo muaj lub zog ua haujlwm siab thiab nkag siab lub zog ntawm qhov kub thiab txias, zoo cuam tshuam rau qhov kub thiab txias, zoo hardenability, tsis muaj cua sov nyiam, me me quenching deformation, siv tau plasticity ntawm txias ntug sib sau thiab nruab nrab txheej txheem.Tsis zoo weldability, preheating ua ntej vuam, tom qab vuam kev kho cua sov thiab kev nyuaj siab nyem feem ntau yog siv tom qab quenching thiab tempering, thiab kuj yuav siv tau tom qab siab thiab nruab nrab zaus nto quenching los yog quenching thiab qis thiab nruab nrab kub tempering.
Lub tuam txhab txhawb nqa lub tswv yim ntawm "Ua No.1 hauv kev ua tau zoo, tau txais txiaj ntsig los ntawm kev ntsuam xyuas credit thiab kev ntseeg siab rau kev loj hlob", yuav txuas ntxiv ua haujlwm tsis tu ncua thiab cov neeg siv khoom tshiab hauv tsev thiab txawv teb chaws rau 2024 Zoo siab ASTM 4140 Chrome Moly Kub Rolled Alloy Steel Pipe, Rau qhov zoo tshaj plaws roj vuam & txiav cov khoom siv raws sijhawm thiab ntawm tus nqi tsim nyog, koj tuaj yeem suav rau lub npe lag luam.
Lub tuam txhab txhawb nqa lub tswv yim ntawm "Ua No.1 hauv kev ua tau zoo, tau txais txiaj ntsig los ntawm kev ntsuam xyuas credit thiab kev ntseeg siab rau kev loj hlob", yuav txuas ntxiv ua haujlwm rau cov neeg siv khoom tshiab thiab cov neeg siv khoom tshiab hauv tsev thiab txawv teb chaws tag nrho-rhuav rauTuam Tshoj Seamless Alloy Steel Yeeb Nkab thiab Alloy Steel Yeeb Nkab, Txhawm rau kom ua tus thawj coj hauv peb txoj kev lag luam, peb yeej tsis tso tseg qhov kev txwv tsis pub dhau txhua yam los tsim cov kev daws teeb meem zoo tshaj plaws.Nyob rau hauv nws txoj kev, Peb tuaj yeem ua kom peb lub neej zoo dua qub thiab txhawb kev nyob ib puag ncig zoo dua rau cov zej zog thoob ntiaj teb.
34CrMo4 / 35CrMo yog siv los ua cov txheej txheem tseem ceeb ua haujlwm nyob rau hauv siab load, xws li kis tau tus mob ntawm cov tsheb thiab cav;Lub rotor, lub ntsiab ncej thiab kis tau tus mob nrog hnyav load ntawm turbo generator, ntu loj 34CrMo4 yog siv los tsim forgings nrog lub zog siab dua thiab loj dua quenching thiab tempering seem tshaj 35CrMo steel, xws li cov iav loj rau locomotive traction, boost kis iav, rear ncej, txuas pas nrig thiab caij nplooj ntoos hlav clamp nrog zoo load.34CrMo4 kuj tseem siv tau rau kev xyaum cov yeeb nkab sib txuas thiab cov cuab yeej nuv ntses hauv cov roj qhov tob hauv qab 2000m.34CrMo4 Gas Lub tog raj kheej yeeb nkab, feem ntau yog siv rau hauv lub tog raj kheej roj teeb, kev tiv thaiv hluav taws, kev kho mob, khoom siv hauv kev lag luam, thiab lwm yam.
Cov pa roj carbon sib npaug CEQ ntawm 35CrMo steel yog 0.72%.Nws tuaj yeem pom tias qhov weldability ntawm cov khoom siv no tsis zoo, thiab nws txoj kev nyuaj siab yog loj thaum vuam.Qhov kub tawg thiab txias tawg nyiam ntawm tshav kub cuam tshuam ntawm 35CrMo alloy yeeb nkab yuav loj.Tshwj xeeb tshaj yog thaum welding nyob rau hauv lub quenched thiab tempered lub xeev, lub txias tawg nyiam ntawm lub tshav kub cuam tshuam cheeb tsam yuav yog ib qho tseem ceeb heev.Yog li ntawd, nyob rau hauv lub hauv paus ntawm kev xaiv cov ntaub ntawv uas tsim nyog welding thiab tsim nyog welding txoj kev, siab dua pre-welding preheating kub Nyob rau hauv cov xwm txheej ntawm nruj txheej txheem ntsuas thiab kom zoo interpass kub tswj, lub hom phiaj ntawm cov khoom vuam yuav ua tiav.
