AISI 4145 Alloy hlau
Mar 28, 2023
Khoom Description
AISI 4145 Alloy Steel, tseem hu ua UNS G41450, yog cov khoom tshwj xeeb nrog ntau yam ntawm cov yam ntxwv zoo kawg li.
Cov hlau alloy no muaj npe nrov rau nws cov tshuaj muaj pes tsawg leeg. Nws muaj qhov sib npaug sib npaug ntawm cov ntsiab lus xws li chromium, molybdenum, thiab manganese, thiab lwm yam. Lub xub ntiag ntawm chromium txhim kho corrosion kuj, thaum molybdenum pab txhawb kom muaj zog thiab hardness. Manganese pab txhim kho cov hlau toughness thiab hardenability.
Nyob rau hauv cov nqe lus ntawm txhua yam khoom, AISI 4145 Alloy Steel yog heev saib. Nws nthuav tawm lub zog tensile zoo heev, ua rau nws tuaj yeem tiv taus qhov 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 muaj qhov zoo ductility, cia nws khoov thiab zoo li tus yam tsis muaj cracking.
Kev kho cua sov teb ntawm AISI 4145 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, cov hlau alloy no 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, AISI 4145 Alloy Steel 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 cov hlau no 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 4145 Alloy Steel (UNS G41450) 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 aerospace, tsheb, roj thiab roj, thiab tshuab.
