Cov qib steel tshwj xeeb no yog tsim los ntawm kev ua tib zoo xaiv ua ke ntawm cov ntsiab lus alloying. Nws muaj cov ntsiab lus xws li txhuas (Al), uas ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa cov txheej txheem nitrided nyuaj thiab ruaj khov thaum lub sijhawm kho nitriding. Lub xub ntiag ntawm chromium (Cr) pab txhawb kev txhim kho corrosion, kom ntseeg tau tias cov hlau tuaj yeem tiv taus ntau qhov chaw corrosive. Tsis tas li ntawd, lwm cov ntsiab lus alloying ua haujlwm hauv kev sib koom ua ke los txhim kho tag nrho cov khoom siv hluav taws xob ntawm cov hlau, suav nrog nws lub zog thiab toughness.
Kev tsim khoom ntawm SACM645 - JIS nitriding steel xav tau qhov tseeb thiab cov txheej txheem siab heev. Nws feem ntau ua tiav cov txheej txheem xws li precision casting lossis forging kom ua tiav cov duab xav tau thiab microstructure. Kev tswj xyuas nruj nruj yog siv thoob plaws hauv cov txheej txheem tsim khoom kom ntseeg tau tias cov hlau ua tau raws li cov qauv tsim los ntawm JIS. Qhov no ua kom muaj kev ua tau zoo thiab txhim khu kev qha, uas yog qhov tseem ceeb rau nws cov ntawv thov hauv ntau qhov kev lag luam.

Thaum nws los txog rau cov ntawv thov, SACM645 - JIS nitriding steel yog dav siv hauv kev tsim cov khoom siv tshuab ua haujlwm siab. Piv txwv li, nws yog feem ntau siv nyob rau hauv kev tsim cov iav, ncej, thiab bearings uas yuav tsum tau zoo heev deg hardness thiab hnav tsis kam ua hauj lwm zoo thiab muaj lub neej ntev kev pab cuam. Hauv kev lag luam automotive, nws tau ua haujlwm nyob rau hauv cov khoom tseem ceeb ntawm lub cav thiab cov khoom sib kis los txhim kho lawv cov kav ntev thiab kev ua haujlwm raws li kev xav tau ntawm kev ua haujlwm. Nyob rau hauv aerospace teb, nws yog siv nyob rau hauv lub Cheebtsam uas yuav tsum tau tiv taus high stresses thiab abrasive ib puag ncig, xws li tsaws iav qhov chaw thiab turbine Cheebtsam.
Cov txheej txheem nitriding siv rau cov hlau no tsis yog tsuas yog txhim kho nws cov khoom nto, tab sis kuj muab cov ntaub ntawv-hardened txheej uas muaj kev tiv thaiv zoo rau qaug zog, hnav, thiab corrosion. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas muaj kev ntseeg siab, ua haujlwm ntev, thiab kev ua haujlwm siab yog qhov tseem ceeb tshaj plaws. Tsis tas li ntawd, kev sib xyaw ua ke ntawm nws qhov tshwj xeeb muaj pes tsawg leeg thiab cov txiaj ntsig ntawm nitriding muab SACM645 - JIS nitriding steel ib qho txiaj ntsig zoo hauv kev lag luam uas precision engineering thiab zoo yog qhov tseem ceeb.
Hauv kev xaus, SACM645 - JIS nitriding steel yog cov khoom tseem ceeb uas ua lub luag haujlwm tseem ceeb hauv kev lag luam niaj hnub no. Nws cov khoom tshwj xeeb thiab ua raws li JIS cov qauv ua rau nws yog ib qho tseem ceeb ntawm kev siv ntau yam. Kev tshawb fawb txuas ntxiv thiab kev tsim kho tshiab hauv thaj tsam ntawm nitriding steels zoo li yuav ua kom zoo dua nws cov kev ua tau zoo thiab nthuav dav nws daim ntawv thov, pab txhawb kev nce qib ntawm cov cuab yeej technology thiab kev txhim kho cov khoom zoo thoob plaws ntau qhov chaw, thiab ua kom muaj kev txhim kho ntau dua thiab txhim khu kev qha engineering daws teeb meem. .
