Lus piav qhia luv luv:
34CrMo4 / 35CrMo muaj lub zog ua haujlwm siab thiab nkag siab 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.
"Control tus qauv los ntawm cov ntsiab lus, qhia lub zog los ntawm qhov zoo".Peb lub lag luam tau siv zog los tsim kom muaj ib pab neeg ua haujlwm tau zoo thiab ruaj khov thiab tshawb nrhiav cov txheej txheem zoo tswj cov txheej txheem rau Quots rau ASTM A519 4130 4140 4340 GB30crmo 42CrMo 35CrMo 15CrMo High Precision Alloy Steel Yeeb Nkab, Nrog rau ntau yam, cov nqi zoo tshaj plaws, stylish designs, Peb cov khoom tau lees paub dav thiab vam khom los ntawm cov neeg siv khoom thiab tuaj yeem ua tiav tsis tu ncua hloov pauv nyiaj txiag thiab kev xav tau ntawm tib neeg.
"Control tus qauv los ntawm cov ntsiab lus, qhia lub zog los ntawm qhov zoo".Peb lub lag luam tau siv zog los tsim kom muaj ib pab neeg ua haujlwm tau zoo thiab ruaj khov thiab tshawb nrhiav cov txheej txheem tswj xyuas zoo rauTuam Tshoj Cold Rolled Steel Tube thiab Precision Steel Tube, Kev txiav txim siab yog txais tau nrog cov qib zoo sib txawv thiab cov neeg siv khoom tsim tshwj xeeb.Peb tau tos ntsoov los tsim kom muaj kev koom tes zoo thiab ua tiav hauv kev lag luam nrog cov lus ntev los ntawm cov neeg siv khoom thoob plaws 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 qhov chaw ntawm lub 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 thaj chaw tshav kub 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.
