GH4648
GH4648 is a Ni-Cr base precipitation hardening deformation superalloy with a long-term service temperature of less than 900 ℃ and a short-term service temperature of 1100 ℃. The alloy is characterized by adding about CR32%, which makes it have excellent hot corrosion resistance. At the same time, the alloy has medium strength, good fatigue and creep resistance, good cold working performance and welding performance. It is suitable for manufacturing high-temperature structural parts with temperature between 900 ℃ and 1000 ℃ and excellent corrosion resistance. The alloy has been used to make advanced aeroengine combustion chamber components and other hot end components, and the batch production and use are good. Similar brands have been widely used in foreign aero-engines.
