Cov khoom siv kho tshuab ntawm 24CrMoV55 steel ua lub luag haujlwm tseem ceeb hauv nws cov ntawv thov ntau yam. Nov yog qee cov piv txwv ntxaws ntawm nws cov khoom siv kho tshuab. Nyob rau hauv cov nqe lus ntawm tensile zog, 24CrMoV55 steel tuaj yeem pom lub zog tensile xws li 800 MPa rau 950 MPa. Lub zog tensile siab no tso cai rau cov hlau kom tiv taus lub zog tseem ceeb yam tsis muaj kev tawg. Nws yog ib qho tseem ceeb nyob rau hauv cov ntawv thov uas qhov kev ncaj ncees ntawm cov qauv yog qhov tseem ceeb, xws li hauv kev tsim kho cov tshuab hnyav lossis cov khoom uas raug kev nyuaj siab. Lub zog tawm los ntawm cov hlau no feem ntau yog nyob ib ncig ntawm 650 MPa rau 800 MPa. Yield zog qhia qhov taw tes ntawm cov khoom pib deform plastically nyob rau hauv load. Cov cuab yeej no tseem ceeb rau kev ua kom ntseeg tau tias cov hlau tuaj yeem tuav cov khoom xav tau yam tsis muaj deformation mus tas li. Hardness yog lwm yam khoom tseem ceeb ntawm 24CrMoV55 steel. Nws tuaj yeem muaj Brinell hardness ntawm 250 HBW txog 320 HBW. Hardness txiav txim siab cov hlau tsis kam rau abrasion thiab hnav. Hauv cov ntawv thov uas muaj kev sib txhuam thiab hnav yog kev txhawj xeeb, xws li hauv cov iav lossis cov khoom siv kho tshuab hauv kev sib cuag nrog lwm qhov chaw, lub hardness ntawm 24CrMoV55 steel muab cov kav ntev thiab ntev. Impact resistance kuj tseem ceeb heev. Lub Charpy cuam tshuam lub zog qhov tseem ceeb ntawm 24CrMoV55 steel tuaj yeem sib txawv, tab sis nws yuav muaj kev cuam tshuam hnyav ntawm ib ncig ntawm 30 J txog 50 J. Cov cuab yeej no qhia tias cov hlau muaj peev xwm nqus tau lub zog tsis muaj kev puas tsuaj thaum raug cuam tshuam tam sim ntawd. Hauv cov ntawv thov uas muaj kev pheej hmoo ntawm dynamic loading los yog cuam tshuam, xws li nyob rau hauv tej yam kev lag luam machinery los yog automotive Cheebtsam, qhov cuam tshuam tsis kam ntawm 24CrMoV55 steel yog qhov tseem ceeb. Zuag qhia tag nrho, kev sib xyaw ua ke ntawm cov khoom siv kho tshuab ua rau 24CrMoV55 steel haum rau ntau yam kev thov. Nws lub zog tensile siab, lub zog tawm los, hardness, thiab kev cuam tshuam tsis kam ua rau nws txoj kev ntseeg siab thiab kev ua tau zoo hauv ntau yam lag luam, suav nrog kev tsim khoom, engineering, thiab kev tsim kho.
