Nyob rau hauv cov nqe lus ntawm nws microstructure, nws muaj ib tug zoo-txhais kev npaj uas pab rau nws tag nrho cov kev ua tau zoo. Cov ntsiab lus alloying cuam tshuam hauv cov hlau matrix los txhim kho nws cov hardness, hnav tsis kam, thiab qaug zog. Qhov no ua rau nws haum rau ntau yam kev siv, tshwj xeeb tshaj yog nyob rau hauv machinery thiab automotive industries.
Piv txwv li, hauv kev siv tshuab, JIS SNCM8 alloy steel feem ntau yog siv rau hauv kev tsim cov iav, shafts, thiab bearings. Nws lub zog siab thiab hnav tsis kam yog qhov tseem ceeb rau cov khoom siv no kom ua haujlwm zoo thiab ua haujlwm tau zoo nyob rau lub sijhawm ntev. Hauv kev lag luam automotive, nws tuaj yeem pom nyob rau hauv cov khoom siv cav xws li crankshafts thiab txuas rods, qhov twg nws yuav tsum tiv taus qhov kub thiab txias, nrawm nrawm, thiab kev vibrations.
Thaum nws los txog rau kev ua thiab kev tsim khoom nrog JIS SNCM8 alloy steel, precision thiab tsim nyog cov txheej txheem yog qhov tseem ceeb. Cov txheej txheem kho cua sov ua lub luag haujlwm tseem ceeb hauv kev ua kom nws cov khoom zoo. Cov txheej txheem kev kho cua sov sib txawv, xws li quenching thiab tempering, tuaj yeem ua haujlwm los kho qhov hardness thiab toughness raws li cov kev cai tshwj xeeb ntawm daim ntawv thov. Kev ua haujlwm machining yuav tsum tau ua nrog qhov tseeb kom ua tiav qhov xav tau qhov ntev thiab qhov zoo. Tsis tas li ntawd, kev tswj xyuas zoo yog qhov tseem ceeb thoob plaws hauv cov txheej txheem tsim khoom los xyuas kom meej qhov sib xws thiab kev ntseeg siab ntawm cov khoom kawg.
