Nyiv JIS G4104 SCr21 steel
Jun 14, 2022
Nyiv JIS G4104 SCr21 steel yog cov khoom siv zoo kawg nkaus nrog cov yam ntxwv sib txawv thiab ntau yam kev siv.
Cov hlau no paub txog nws cov khoom siv kho tshuab zoo heev. Nws muaj lub zog tensile siab, ua rau nws tiv taus cov khoom hnyav thiab kev ntxhov siab. Lub zog tawm los ntawm SCr21 steel kuj zoo kawg nkaus, kom ntseeg tau tias nws tsis deform yooj yim nyob rau hauv siab. Qhov no ua rau nws zoo tagnrho rau kev siv cov khoom siv hauv cov khoom siv thiab cov tshuab ua haujlwm uas yuav tsum tau ua kom ntev thiab kev ntseeg tau.
Ntxiv rau nws lub zog, SCr21 steel muaj qhov zoo hardness thiab hnav tsis kam. Nws tuaj yeem tiv taus kev puas tsuaj thiab deformation, ua rau nws tsim nyog rau cov ntawv thov uas qhov chaw raug kev sib txhuam thiab kev cuam tshuam. Cov cuab yeej no ua rau nws muaj kev xaiv nrov rau cov iav, ncej, thiab bearings.
Cov tshuaj muaj pes tsawg leeg ntawm SCr21 steel muaj xws li carbon, chromium, thiab manganese. Carbon muab hardness thiab lub zog, thaum chromium txhim khu hardness, hnav tsis kam, thiab corrosion kuj. Manganese pab txhawb rau cov hlau lub toughness thiab ductility.
Cov txheej txheem tsim khoom ntawm SCr21 steel koom nrog kev tswj xyuas kom zoo ntawm cov ntsiab lus alloying, kev kho cua sov, thiab dov. Qhov no ua kom cov hlau muaj qhov sib xws microstructure thiab zoo ib yam. Cov txheej txheem ntau lawm yog siv los ua kom tiav qhov ntev thiab qhov chaw tiav.
SCr21 steel tuaj yeem ua tiav los ntawm kev siv tshuab, vuam, thiab kev kho cua sov kom tau raws li cov qauv tsim tshwj xeeb. Nws tuaj yeem raug txiav, drilled, thiab welded los tsim cov duab thiab cov qauv. Cov txheej txheem kho cua sov xws li quenching thiab tempering tuaj yeem siv los kho cov hardness thiab lub zog ntawm cov hlau.
Nyob rau hauv xaus, Nyiv JIS G4104 SCr21 steel yog ib tug high-kev ua tau zoo alloy steel nrog zoo heev mechanical zog, hardness, hnav tsis kam, thiab corrosion kuj. Nws cov yam ntxwv tshwj xeeb ua rau nws muaj txiaj ntsig kev xaiv rau ntau yam kev siv hauv ntau yam lag luam. Txawm hais tias nws yog rau cov khoom siv, cov khoom siv, lossis lwm yam kev siv, SCr21 steel muaj kev ua tau zoo thiab ua haujlwm ntev.
