AISI 4118 Hlau
Aug 09, 2022
Khoom Description
AISI 4118 steel yog cov khoom siv zoo kawg nkaus nrog cov tswv tsev zoo heev.
Cov hlau no paub txog nws cov tshuaj muaj pes tsawg leeg. Nws muaj cov khoom sib xyaw xws li carbon, chromium, manganese, thiab molybdenum, thiab lwm yam. Lub xub ntiag ntawm cov ntsiab lus no muab AISI 4118 steel nws cov khoom tshwj xeeb.
Hais txog cov khoom siv kho tshuab, AISI 4118 steel tau txais txiaj ntsig zoo. Nws muaj lub zog tensile zoo heev, ua rau nws tiv taus cov khoom hnyav thiab kev ntxhov siab. Lub zog tawm los kuj tseem ceeb, kom ntseeg tau tias cov khoom tsis yooj yim deform nyob rau hauv siab. Tsis tas li ntawd, cov hlau no nthuav tawm zoo ductility, cia nws khoov thiab zoo li tus yam tsis muaj kev tawg.
Kev kho cua sov teb ntawm AISI 4118 steel yog lwm qhov tseem ceeb. Nws tuaj yeem raug kho los ntawm cov txheej txheem xws li quenching thiab tempering kom ua tiav cov qib hardness tshwj xeeb thiab cov khoom siv kho tshuab. Qhov no ua rau nws haum rau ntau yam kev siv uas xav tau kev sib xyaw ua ke ntawm lub zog, toughness, thiab hnav tsis kam.
Hais txog kev hnav tsis kam, AISI 4118 steel ua tau zoo heev. Nws tuaj yeem tiv taus kev puas tsuaj thiab kev sib txhuam, ua rau nws zoo tagnrho rau cov khoom xws li lub zog, cov ncej, thiab cov cuab yeej uas raug coj mus tas li thiab kev ntxhov siab.
Ntxiv mus, cov hlau no muaj kev qaug zog zoo. Nws tuaj yeem tiv taus kev thauj mus los thiab kev thauj mus los yam tsis muaj kev puas tsuaj loj, muab lub neej ua haujlwm ntev hauv kev xav tau.
Lub machinability ntawm AISI 4118 steel kuj zoo heev. Nws tuaj yeem ua tiav siv ntau yam kev siv tshuab, suav nrog kev tig, milling, thiab drilling, kom ua tiav cov duab thiab qhov ntev.
Zuag qhia tag nrho, AISI 4118 steel yog cov khoom siv ntau yam thiab txhim khu kev qha. Nws ua ke ntawm lub zog, hardness, hnav tsis kam, qaug zog, thiab machinability ua rau nws muaj kev xaiv nrov hauv kev lag luam xws li tsheb, tshuab, thiab kev tsim khoom. Txawm hais tias siv rau hauv kev tsim cov iav, ncej, lossis lwm yam khoom, AISI 4118 steel muaj kev ua tau zoo thiab ua haujlwm ntev.
