Dab tsi yog qhov txawv ntawm 15CrMo thiab 12Cr1MoV?
15CrMo steel yog cov cua kub-resistant steel nrog pearlite qauv, tus qauv txheem: GB / T 3077-2015. 15CrMo muaj lub zog thermal siab (δb Ntau dua lossis sib npaug ntawm 440MPa) thiab oxidation tsis kam ntawm qhov kub thiab txias, thiab muaj qee yam tsis kam rau hydrogen corrosion. Txij li cov hlau muaj cov ntsiab lus siab ntawm Cr, C thiab lwm yam hlau alloying, cov hlau muaj qhov pom tseeb hardening nyiam thiab tsis zoo weldability. 15CrMo feem ntau yog siv rau hauv crankshafts, lub zog, camshafts ntawm lub tshuab hluav taws xob sab hauv, thiab cov iav hauv cov khoom tseem ceeb.
12Cr1MoV lub teb chaws tus qauv kev ua tau zoo alloy cov qauv hlau, kev siv tus qauv: GB / T 3077-201512Cr1MoV muaj ntau dua oxidation tsis kam thiab thermal zog. Lub creep txwv ntawm cov hlau no yog ze heev rau lub zog ruaj khov tus nqi, thiab nws muaj siab plasticity nyob rau hauv sustained stretching; cov hlau muaj cov txheej txheem zoo thiab kev sib txuas, tab sis nws yuav tsum tau preheated rau 300 degree ua ntej vuam, thiab kev ntxhov siab yuav tsum tau tom qab vuam. deal nrog. Cov hlau no feem ntau yog siv tom qab normalizing thiab kub kub firing los ua superheated steel kav, conduits, serpentine kav thiab lwm yam sib thooj forgings nyob rau hauv high-pressure khoom uas nws ua hauj lwm kub tsis tshaj 570-585 degree.
