45CrNiMoVA Cov Khoom Siv Hluav Taws Xob Hlau Bar
45CrNiMoVA puag ncig steel yog ib hom qis alloy ultra- siab zog steel. Cov hlau muaj siab hardenability. Qhov tseem ceeb hardenable txoj kab uas hla hauv cov roj yog 60mm (96% martensite). Cov hlau tuaj yeem tau txais lub zog siab tom qab quenching thiab tempering. Nws yog cov qauv hlau alloy uas muaj qee qib ntawm toughness thiab tuaj yeem ua tiav rau hauv cov duab.

45CrNiMoVA puag ncig Tshuag hlau Cov Khoom Paub meej
45CrNiMoVA puag ncig bar yog qis- alloy ultra-siab- lub zog steel. Peb lub teb chaws tau tsim D6AC alloy steel nrog high yield- mus rau - lub zog piv, siab zog, zoo toughness, siab siab - kub lub zog, thiab tsis temper brittleness. Cov hlau no muaj qhov tawv tawv siab thiab hnav tsis kam tom qab nkag mus quenching, nruab nrab machinability, nruab nrab plasticity thaum lub sij hawm txias deformation, tab sis me ntsis rhiab heev thiab temper brittleness. Feem ntau siv tom qab carburizing, theem nrab quenching thiab kub tempering. Tom qab carburizing thiab qis kub theem nrab quenching thiab tempering, nws yog siv los tsim cov khoom loj carburized nrog siab load. Nws yuav tsum tau siv tom qab normalizing los yog annealing, quenching thiab tempering.
45CrNiMoVA steel pas nrig yog cov khoom siv zoo heev rau kev lag luam aerospace nrog lub zog siab, zoo toughness thiab tawg propagation kuj, nrog rau zoo corrosion kuj thiab zoo tag nrho cov kev ua tau zoo. Vim nws cov hardenability siab thiab ntau yam ntawm cov txheej txheem kho cua sov, cov khoom zoo siab tuaj yeem tau txais los ntawm kev kho cua sov. Alloy steel yog siv dav hauv cov qauv dav hlau tseem ceeb, xws li tsaws iav, khoom siv roj foob pob hluav taws cav, shafts, zog, bearings, tuag, pads, thiab lwm yam.
