Sehlahisoa SEHLOOHO
GH738 ke alloy e thehiloeng ho mocheso o phahameng oa nickel e thatafalitsoeng ke pula ea γ' phase, e nang le khanyetso e ntle ea khase, matla a chai e ngata le thepa ea mokhathala, mokhoa o motle oa polasetiki le mokhatlo o tsitsitseng. E sebelisoa haholo likarolong tse potolohang tsa enjene ea sefofane, ts'ebeliso ea mocheso ha e phahametse 815 ℃. E ka hlahisa lipoleiti tse kolobisitsoeng tse batang le tse chesang, liphaephe, likhoele, lithapo, li-forging, li-castings le li-fasteners.
Sesebelisoa sa sehlahisoa
Lienjine tsa lifofane, li-turbine tsa mochini tsa khase, li-blade tsa turbine le li-disk tsa turbine le likarolo tse ling tse potolohang.
