GH3030 yolimba yankho lolimba la superalloy ndi njira yolimba yolimba ya 80Ni-20Cr yolimbitsa ma superalloy.Ili ndi mawonekedwe osavuta amankhwala, mphamvu yokwanira yotentha komanso mapulasitiki apamwamba pansi pa 800 ℃, komanso kukana kwa okosijeni, kutopa kwamafuta, kupondaponda kozizira komanso njira zowotcherera.
Pambuyo pa chithandizo chamankhwala, aloyi ndi gawo limodzi la austenite, ndipo kapangidwe kake kamakhala kokhazikika pakagwiritsidwa ntchito.
Zida zopangira injini za turbine kuti zigwiritsidwe ntchito pansi pa 800 ℃ ndi zida zina zotentha kwambiri zomwe zimafunikira kukana kwa okosijeni koma sizimanyamula katundu wochepera 1100 ℃.
GH3030 imagwira ntchito mwamphamvu pakukonza zinyalala zozizira zotentha, zomwe zimagwiritsidwa ntchito popanga zida zosiyanasiyana zama mankhwala ndi zowonjezera.

• Solid solution imalimbitsa ma superalloy, mawonekedwe osavuta amankhwala,
•Ili ndi mphamvu yokwanira yotenthetsera komanso mapulasitiki apamwamba pansi pa 800 ℃.
•Ndipo ali wabwino kukana makutidwe ndi okosijeni, kutopa matenthedwe, ozizira stamping ndi kuwotcherera ndondomeko katundu.
•Pambuyo pa chithandizo chamankhwala, aloyi ndi gawo limodzi la austenite, ndipo kapangidwe kake kamakhala kokhazikika pakagwiritsidwa ntchito.
GH3030 Ntchito mugawo:
Aloyiyo yakhala ikugwiritsidwa ntchito mu injini ya aero kwa nthawi yayitali, ndipo imagwiritsidwa ntchito kwambiri popangira zida zoyatsira moto ndi zoyatsira moto komanso zigawo za m'mphepete mwa casing.
