Cov khoom siv dab tsi yog 12CrNi3?

12CrNi3 steel belongs rau alloy carburized steel thiab muaj zog hardenability dua 12CrNi2A hlau. Yog li ntawd, nws tuaj yeem siv los tsim cov khoom siv nrog cov ntu loj me me dua li 12CrNi2A steel.
Cov hlau muaj cov khoom zoo txhua yam tom qab quenching, low-temperature tempering, lossis high-temperature tempering. Cov hlau muaj qhov kub thiab txias toughness, me me rhiab heev, thiab kev ua haujlwm zoo. Thaum lub hardness yog HB260-320, tus txheeb ze txiav peev xwm yog 60 feem pua ​​~ 70. Tsis tas li ntawd, cov hlau tsis tshua muaj hardness thiab zoo plasticity tom qab annealing. Yog li ntawd, nws tuaj yeem tsim los ntawm kev txiav lossis txias extrusion txoj kev. Txhawm rau txhim kho qhov hnav tsis kam ntawm pwm kab noj hniav, kev kho mob carburization yuav tsum tau ua tom qab pwm tsim, ua raws li quenching thiab qis-temperature tempering los xyuas kom meej tias qhov saum npoo ntawm pwm muaj siab hardness thiab hnav tsis kam, thaum cov tub ntxhais muaj qhov zoo toughness. Cov hlau no yog tsim rau kev tsim cov yas pwm loj thiab nruab nrab. Tab sis cov hlau muaj temper brittleness nyiam thiab dawb qhov chaw nyiam.
Cov yam ntxwv thiab Scope ntawm daim ntawv thov
Nws yog qib high-qib carburized steel nrog ntau yam kev siv. Piv nrog 15Cr thiab 20Cr steels, nws muaj zog dua, plasticity, thiab hardenability. Feem ntau yog siv los tsim cov spindles uas yuav tsum tau muaj zog, hardness, thiab toughness nyob rau hauv hnyav load tej yam kev mob, raws li zoo raws li shafts thiab rods uas yuav tsum tau high center toughness los yog withstand tej yam loads, nto hnav tsis kam, thiab me me tshav kub kev kho mob deformation, raws li zoo raws li ntau yam kis tau tus mob. gears, kho cov ntsia hlau, thiab camshafts uas ua haujlwm nyob rau hauv high-ceev thiab cuam tshuam loads
