GH4037 (GH37) alloy yog austenite-type age-hardened nickel-based alloy. Nws yog ntxiv nrog rau tag nrho ntawm 4% txhuas thiab titanium los tsim cov theem rau hnub nyoog-hardening, thiab ntau tungsten thiab molybdenum ntxiv rau cov khoom siv ntxiv zog. Ib txoj kab ntawm boron kuj ntxiv ntxiv kom ntxiv dag zog rau cov ciam teb. Cov hlau yog siv qis dua 850 degree, muaj lub zog thermal siab, kev ua haujlwm zoo thiab kev ruaj ntseg, thiab yog siv dav hauv kev tsim cov dav hlau cav turbine hniav. Nws yog siv rau lub sijhawm ntev hauv qab no 800-850 degree .

Kev npaj ntawm Superalloy GH4037
Cov txheej txheem kev npaj ntawm GH4037 alloy feem ntau suav nrog smelting, casting, kho cua sov thiab machining. Thaum lub sij hawm smelting txheej txheem, muaj pes tsawg leeg ntawm cov hlau thiab qhov kub ntawm lub pas dej molten yuav tsum tau tswj kom cov hlau muaj cov tshuaj muaj pes tsawg leeg zoo thiab niaj hnub microstructure. Thaum lub sij hawm casting txheej txheem, lub casting kub thiab txias npaum li cas yuav tsum tau tswj kom tsis txhob tawg thiab residual kev nyuaj siab ntawm alloy. Thaum lub sij hawm kho cua sov txheej txheem, lub aging kub thiab aging lub sij hawm yuav tsum tau tswj kom tau zoo tagnrho alloy khoom. Thaum kawg, cov hlau yog tsim rau hauv cov duab uas xav tau thiab loj los ntawm machining.
Daim ntawv thov teb ntawm GH4037 alloy
Vim nws qhov kev ua tau zoo ntawm qhov kub thiab txias tsis kam, GH4037 alloy yog dav siv hauv aerospace, shipbuilding, petrochemical, lub zog thiab lwm yam. Piv txwv li, hauv thaj chaw aerospace, GH4037 alloy tuaj yeem siv los tsim cov khoom kub xws li turbine blades, combustion chambers thiab gas superchargers. Nyob rau hauv lub nkoj tsim, GH4037 alloy tuaj yeem siv los tsim cov nkoj tiv thaiv corrosion-resistant thiab kub resistant steering log. Hauv petrochemical teb, GH4037 alloy tuaj yeem siv los tsim cov reactors thiab catalysts. Nyob rau hauv lub zog teb, GH4037 alloy yuav siv tau los tsim kub kub exchangers thiab roj turbine generator teeb.
