3. Cov yam ntxwv tseem ceeb ntawm GH3030 Alloy
Siab -Tsub Muaj Zog:Nws muaj qhov txaus siab siab - qhov kub thiab txias, tswj kev ruaj ntseg thiab kev ncaj ncees ntawm qhov kub txog li 800℃-900 degree, thiab tsim nyog rau cov ntawv thov uas xav tau oxidation tsis kam tab sis nrog qis loads txog 1100 degree.
Oxidation Resistance:Vim nws siab -nickel-chromium matrix, nws pom zoo oxidation tsis kam, tshwj xeeb tshaj yog thaum kub.
Microstructure Stability:Tom qab kev daws teeb meem, cov hlau no nthuav tawm ib qho -theem austenitic qauv, nyob ruaj khov thaum lub sij hawm ntev - lub sij hawm siab - kub kev pab cuam.
Machinability zoo heev:Nws muaj cov yas siab, haum rau txias stamping, thiab nthuav tawm cov khoom txias thiab kub ua haujlwm zoo.
Weldability:Nws muaj qhov zoo weldability thiab tuaj yeem siv rau hauv ntau yam txheej txheem vuam los tsim cov khoom siv.
Siab Thermal Fatigue Resistance: Nws ua tau zoo heev nyob rau hauv tej yam kev mob uas yuav tsum tau muaj kev qaug zog tsis kam thiab thermal cycling kuj.
4. Kev siv ntau ntawm GH3030 Alloy
GH3030 feem ntau yog siv rau hauv ib puag ncig uas yuav tsum tau ua kom sov siab thiab oxidation tsis kam, suav nrog:
Aerospace:Turbine engine combustion chamber Cheebtsam.
Industrial:Afterburners, combustion chambers, thiab kub -kawg Cheebtsam (nrog rau vaj tse).
Kev ua tshuaj lom neeg:High -cov thawv kub thiab cov khoom siv.
5.Kev sib piv ntawm cov khoom ruaj khov ntawm GH3030 thiab GH4169 hnub nyoog- hardening alloy
| Feature | GH3030 (Tshuaj-Kev daws teeb meem) | GH4169 (Nyob rau hauv dej nag-Hardened) |
