20Cr sib npaug|Mechanical Properties
Sep 22, 2022
20Cr steel muaj ntau qhov sib npaug thiab nthuav tawm cov khoom siv kho tshuab zoo kawg.
Hais txog qhov sib npaug, muaj lwm cov hlau uas muaj cov tshuaj zoo sib xws thiab cov yam ntxwv uas tuaj yeem suav tias yog lwm txoj hauv kev rau 20Cr. Cov sib npaug no tuaj yeem yog los ntawm cov qauv sib txawv lossis cheeb tsam tab sis muaj kev sib piv hauv qee yam kev siv. Piv txwv li, qee qhov sib npaug thoob ntiaj teb yuav muaj cov ntsiab lus zoo sib xws thiab cov khoom siv kho tshuab, ua rau lawv hloov tau raws li cov kev xav tau tshwj xeeb ntawm ib qhov project.
Hais txog cov khoom siv kho tshuab, 20Cr steel paub txog nws lub zog thiab kav ntev. Nws muaj lub zog tensile zoo, uas tso cai rau nws tiv taus cov khoom tseem ceeb yam tsis muaj kev tawg. Lub zog tawm los ntawm 20Cr kuj tseem ceeb, qhia tias nws muaj peev xwm tiv thaiv deformation hauv kev ntxhov siab. Qhov no ua rau nws tsim nyog rau cov ntawv thov uas muaj kev ncaj ncees yog qhov tseem ceeb, xws li hauv cov khoom siv thiab cov khoom siv.
Ntxiv nrog rau lub zog, 20Cr steel nthuav tawm qhov tawv tawv. Nws tuaj yeem tiv taus kev puas tsuaj thiab hnav, ua rau nws haum rau qhov chaw uas raug kev sib txhuam thiab kev cuam tshuam. Lub hardness ntawm 20Cr tuaj yeem hloov kho los ntawm cov txheej txheem kho cua sov, tso cai rau kev hloov kho kom tau raws li cov kev xav tau tshwj xeeb.
Tsis tas li ntawd, 20Cr steel muaj ductility zoo, uas txhais tau tias nws tuaj yeem deformed yam tsis muaj cracking. Cov cuab yeej no yog ib qho tseem ceeb rau cov ntawv thov uas cov khoom yuav tsum tau ua los yog tsim. Nws kuj tseem ua rau cov hlau muaj peev xwm nqus tau lub zog thaum muaj kev cuam tshuam.
Cov khoom siv kho tshuab ntawm 20Cr steel ua rau nws muaj ntau yam khoom siv rau ntau yam kev siv. Txawm hais tias nws nyob hauv kev lag luam tsheb, kev tsim khoom, lossis kev tsim kho, 20Cr tuaj yeem muab kev ua tau zoo thiab ua haujlwm ntev.
Hauv kev xaus, 20Cr steel muaj qhov sib npaug uas tuaj yeem txiav txim siab hauv ntau qhov xwm txheej, thiab nws khav theeb cov khoom siv zoo xws li lub zog, hardness, thiab ductility. Kev nkag siab txog cov yam no tuaj yeem pab engineers thiab cov neeg tsim qauv xaiv cov khoom tsim nyog rau lawv cov haujlwm tshwj xeeb.
