4140 Alloy Steel Bar rau Shafts, Gears thiab Hnyav -Lub luag haujlwm Mechanical Parts

Thaum cov neeg yuav khoom xaiv 4140 steel bar, lawv feem ntau tab tom nrhiav ntau tshaj li qhov yooj yim machinability. Qhov laj thawj tseem ceeb ntawm kev xaiv 4140 yog nws lub peev xwm ua kom muaj zog ntau dua los ntawm kev kho cua sov thaum tuav cov tawv zoo.

Hauv kev yuav khoom tiag tiag, 4140 feem ntau yog siv rau kev sib kis, lub zog, bolts, spindles, hydraulic Cheebtsam, thiab cov khoom siv mining. Piv nrog rau cov qib carbon steel zoo tib yam, nws muaj kev hnav zoo dua thiab cov khoom hnyav dua -cov kabmob muaj peev xwm, ua rau nws yog qhov kev xaiv nrov rau kev thov siv tshuab.

Vim Li Cas Ntau Cov Neeg Siv Khoom Siv Hluav Taws Xob Xaiv 4140

Teb zoo heev rau kev kho cua sov

Ib qho ntawm qhov zoo tshaj plaws ntawm 4140 yog nws hardenability. Tom qab quenching thiab tempering, cov khoom tuaj yeem ua tiav lub zog ntau dua li cov qauv carbon steels, ua rau nws tsim nyog rau cov khoom raug rov ua dua.

Zoo dua hnav tsis kam rau cov khoom txav

Rau shafts, gears, couplings, thiab hydraulic rods, nto hnav feem ntau yog ib qho kev txhawj xeeb. Cov ntsiab lus chromium thiab molybdenum hauv 4140 pab txhim kho hnav tsis kam piv nrog cov qib qis - carbon.

Tsim nyog rau Loj -Diameter Parts

Ntau lub tshuab tsim siv 4140 rau hnyav- ntu ntu vim nws tswj cov khoom siv kho tshuab zoo dua tom qab kev kho cua sov dua li cov pa roj carbon zoo tib yam.

Txo kev pheej hmoo ntawm kev ua tsis tiav ntxov ntxov

Nyob rau hauv daim ntawv thov uas muaj torque, cuam tshuam, los yog cyclic kev nyuaj siab, 4140 muab ib tug zoo tshuav nyiaj li cas ntawm lub dag lub zog thiab toughness, pab txuas ntxiv kev pab cuam lub neej.
