GH2747 (GH747) yog dab tsi?
GH2747 (tus thawj lub npe GH747) yog hlau-nickel-raws li nag lossis daus hardening deformed high-temperature alloy nrog kev ua tau zoo heev. Cov hauv qab no yog cov yam ntxwv tseem ceeb ntawm cov hlau no:
Kev ua haujlwm kub siab: Thaum GH2747 alloy siv rau hauv cov khoom siv tshuaj, lub sijhawm ua haujlwm ntev tuaj yeem ncav cuag 1100-1250 degrees Celsius, thiab lub sijhawm ua haujlwm luv luv tuaj yeem ncav cuag 1300 degrees Celsius. Qhov no ua rau nws zoo tagnrho rau kev siv nyob rau hauv qhov chaw kub kub. Lub zog thiab ruaj khov: Cov hlau muaj lub zog siab thiab kev ruaj ntseg zoo, uas txhais tau tias nws tuaj yeem tswj hwm nws qhov kev ua tau zoo nyob rau hauv huab cua yam tsis muaj kev puas tsuaj. Antioxidation thiab corrosion kuj: GH2747 alloy muaj zoo kub oxidation tsis kam thiab corrosion kuj, uas tso cai rau nws kom ruaj khov thiab lifespan nyob rau hauv hnyav ib puag ncig.
Kev tsim thiab vuam: Vim nws yooj yim tsim thiab vuam zog, GH2747 alloy tuaj yeem siv los tsim cov khoom siv dav hlau thiab dav hlau. Scope ntawm daim ntawv thov: Cov alloy no tau dav siv nyob rau hauv zus tau tej cov high-temperature thiab oxidation-resistant Cheebtsam nyob rau hauv aviation thiab aerospace engine combustion chambers thiab afterburners. Nyob rau tib lub sijhawm, nws kuj tseem tsim nyog rau cov khoom siv hluav taws xob tiv thaiv hluav taws xob xws li cov tshuab hluav taws xob, cov khoom siv sib kis, thiab cov thermowells. Nws muaj cov ntawv thov tseem ceeb hauv cov khoom siv hluav taws xob kub tiv thaiv oxidation hauv petrochemical, nuclear zog, metallurgy thiab lwm yam haujlwm.
Cov khoom lag luam thoob ntiaj teb sib xws: GH2747 kuj tseem muaj cov npe thoob ntiaj teb sib xws, xws li HAYNES 747 (USA), 3N747 (Russia), qhia tias nws yog cov khoom siv dav dav thiab siv tau.
