Feature
GH99 yog Ni-Cr raws nag lossis daus hardening deformation siab kub alloy, uas tuaj yeem siv tau ntev hauv qab 900 ° C, thiab lub sijhawm luv luv qhov kub siab tshaj plaws tuaj yeem ncav cuag 1000 ° C. GH99 alloy yog ntxiv dag zog los ntawm kev ntxiv chromium, cobalt, tungsten thiab molybdenum rau cov khoom siv ntxiv dag zog, aluminium thiab titanium los tsim cov txheej txheem laus zog, thiab boron, cerium thiab magnesium kom huv thiab ntxiv dag zog rau cov ciam teb.GH99 alloy muaj ntau dua thermal zog, ruaj khov thiab txaus siab rau cov khoom txias, thiab cov khoom kub zoo. GH99 alloy muaj lub zog thermal, kev ruaj ntseg, thiab muaj kev txaus siab kub thiab txias ua kev tsim thiab vuam txheej txheem kev ua tau zoo.GH99 yog tsim rau kev tsim cov aero-engine combustion chambers thiab roj combustion chambers thiab lwm yam high-temperature welded structural qhov chaw.Cov khoom tseem ceeb ntawm GH99 yog kub-kuav los tiag hlau, tuav, thiab lwm yam. Nrog rau cov hlau tsim los ntawm cov qauv phaj loj, tuaj yeem siv ncaj qha tom qab cov khoom siv kho mob tsis muaj kev laus kho. Cov hlau tsis tau pom tias muaj cov theem teeb meem tom qab kev laus mus ntev ntawm 700 ℃ ~ 950 ℃.
