Txias deformation plasticity yog siab, feem ntau rau khoov, calendering, dabtsi yog khoov thiab rauj arch processing, welding kev ua tau zoo ntawm arc vuam thiab kev sib cuag vuam yog zoo, roj vuam thickness me me, cov duab ntawm nruj nruj los yog complex duab ntawm lub workpiece yog yooj yim tawg. .Txias extruded, carburized hardened steel.Cov hlau belongs rau cov pa roj carbon tsawg, cov hlau tsis muaj zog, toughness, plasticity thiab weldability zoo.≥245MPa, ≥402MPa, ≥28%.Nws yog siv los tsim ntau yam khoom siv kho tshuab uas tsis raug kev ntxhov siab tab sis yuav tsum tau muaj zog toughness.Hauv cov tshuab dav dav thiab tsheb, cov tshuab ua liaj ua teb rau kev tsim cov txheej txheem siab hardness thiab lub siab xav tau ntawm carburizing thiab carburizing qhov chaw.

S45C steel yog ua los ntawm cov hlau zoo li qub los ntawm lub tshuab hluav taws xob, qhib qhov cub lossis cov txheej txheem oxygen dawb huv.Cov hlau muaj cov qauv microstructure thiab tsis muaj microstructure defects.Cov ntsiab lus carbon ntawm cov hlau yog ntau tshaj 0.4%, zoo heev hnav tsis kam, tab sis cov ductility yog txo, quenching yog ib qho yooj yim rau deformation thiab tawg, yog li kev kho cua sov yog ib qho tseem ceeb heev, thiab yuav tsum tau quenched tom qab tempering, kom tsis txhob muaj qhov tshwm sim. tempering brittleness.Lub machinability ntawm hom carbon hlau no tuaj yeem txhim kho los ntawm spheroidizing cov hlau.S45C yog lub zog siab nruab nrab carbon zoo hlau.Nws yog feem ntau siv nyob rau hauv ib txwm hluav taws.Thaum cov khoom siv hluav taws xob ntawm kev xav tau siab dua, kev siv tempering kho.Txias deformation plasticity nruab nrab, annealing thiab normalizing workability yog zoo dua tempering.Siv rau kev tsim cov khoom uas xav tau lub zog siab dua, xws li iav, ncej, piston tus pin, nrog rau cov khoom ua haujlwm, forging, stamping qhov chaw thiab bolts, txiv ntseej, yeeb nkab txuas, thiab lwm yam. 45C yog dav siv hauv kev tsim khoom.Cov hlau no muaj cov khoom siv zoo.
