GH99 yog Ni-Cr raws nag lossis daus hardening deformation siab kub alloy, uas tuaj yeem siv rau lub sijhawm ntev hauv qab 900 ° C, thiab qhov siab tshaj plaws rau lub sijhawm luv luv tuaj yeem ncav cuag 1000 ° C. GH99 alloy yog ntxiv dag zog los ntawm kev sib ntxiv ntawm chromium, cobalt, tungsten thiab molybdenum rau cov khoom siv ntxiv dag zog, los ntawm kev sib ntxiv ntawm txhuas thiab titanium los ua cov txheej txheem kev laus, thiab los ntawm kev sib ntxiv ntawm boron, cerium thiab magnesium kom huv thiab ntxiv dag zog rau cov ciam teb. GH99 alloy muaj lub zog thermal zog, ruaj khov, thiab muaj kev txaus siab kub thiab txias machining txoj kev 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 plates, tuav thiab tuav. 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. Alloy los ntawm 700 ℃ ~ 950 ℃ ntev kev laus tsis pom cov theem teeb meem.

Cov hlau tau siv rau hauv kev tsim cov tshuab aero-engine ua adjustable nozzle plhaub, lub zog chim thiab lwm yam; dov bar tau siv nyob rau hauv kev tsim cov aero-engine compressor hniav; forged bar tau siv nyob rau hauv kev tsim cov loj naval gas turbines thiab cruise missiles structural Cheebtsam.
