GH99 ndi Ni-Cr based precipitation hardening deformation high heat alloy, yomwe ingagwiritsidwe ntchito kwa nthawi yaitali pansi pa 900 ° C, ndipo kutentha kwakukulu kwa nthawi yochepa kumatha kufika 1000 ° C. GH99 alloy imalimbikitsidwa ndi kuwonjezera kwa chromium, cobalt, tungsten ndi molybdenum kuti ikhale yolimba yothetsera yankho, powonjezera aluminium ndi titaniyamu kuti apange magawo okalamba, komanso kuwonjezera boron, cerium ndi magnesium kuti ayeretse ndi kulimbikitsa malire a tirigu. Aloyi ya GH99 ili ndi mphamvu zotentha kwambiri, bungwe lokhazikika, ndipo imakhala ndi makina otenthetsera komanso ozizira opangira makina opangira ndi kuwotcherera.GH99 ndiyoyenera kupanga zipinda zoyatsira injini ya aero-injini ndi zipinda zoyatsira mafuta ndi zigawo zina zowotcherera zotentha kwambiri.Zogulitsa zazikulu za GH99 ndi ma platesging, ma waya opukutira ndi ma waya opukutira. Ndi aloyi chopangidwa ndi dongosolo lalikulu mbale, angagwiritsidwe ntchito mwachindunji pambuyo njira olimba Chithandizo popanda ukalamba Chithandizo. Aloyi ndi 700 ℃ ~ 950 ℃ ukalamba wautali sanapeze magawo owopsa.

Aloyi wakhala ntchito kupanga aero-injini processing chosinthika nozzle chipolopolo, mphamvu mbiya ndi mbali zina; mipiringidzo yakhala ikugwiritsidwa ntchito popanga ma aero-injini kompresa masamba; bar forged akhala akugwiritsidwa ntchito popanga ma turbine akuluakulu apanyanja apanyanja ndi zida zopangira zida zapamadzi.
