Cov tshuaj muaj pes tsawg leeg ntawm 40CrNiMoA yog ua tib zoo sib npaug kom ua tiav nws cov khoom tsim nyog. Nws muaj chromium (Cr), uas muab kev tiv thaiv corrosion thiab txhim khu cov hlau hardness. Nickel (Ni) txhim kho qhov toughness thiab ductility, thaum molybdenum (Mo) ntxiv zog thiab kub ua hauj.
Thaum nws los txog rau kev ua, 40CrNiMoA tuaj yeem ua tau yooj yim, txawm hais tias tsim nyog machining tsis thiab cov cuab yeej yuav tsum raug xaiv los xyuas kom meej qhov zoo ntawm qhov tiav thiab qhov tseeb. Nws tuaj yeem raug kho cua sov kom ua kom zoo dua nws cov khoom siv kho tshuab, xws li los ntawm quenching thiab tempering txheej txheem.
Hauv kev ua lag luam, qhov muaj 40CrNiMoA tuaj yeem sib txawv nyob ntawm tus neeg muag khoom thiab cov kev xav tau ntawm kev lag luam tam sim no. Nws yog ib qho tseem ceeb los muab nws los ntawm cov neeg muab kev ntseeg siab kom ntseeg tau qhov zoo thiab sib xws ntawm cov khoom.
Zuag qhia tag nrho, 40CrNiMoA yog ib qho tseem ceeb alloy hlau uas ua lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam. Nws ua ke ntawm lub zog, toughness, thiab lwm yam khoom tsim nyog ua rau nws nyiam xaiv rau ntau yam kev siv, ua rau kev ua tau zoo thiab kev ntseeg siab ntawm ntau yam khoom thiab cov qauv. Txawm hais tias nws yog siv rau hauv kev tsim kho cov tshuab hnyav, kev lag luam tsheb, lossis lwm yam kev lag luam, 40CrNiMoA tseem ua pov thawj nws muaj nqis thiab qhov tseem ceeb. Txawm li cas los xij, nws yog ib qho tsim nyog los sab laj nrog cov kws tshaj lij cov khoom siv lossis cov kws tsim khoom los txiav txim siab siv cov kev tsim nyog tshaj plaws thiab cov txheej txheem ua tiav raws li cov kev xav tau tshwj xeeb.
