Alloys are divided into ordinary and high-quality categories based on composition. High-quality GH4169 alloys have stricter control over carbon, niobium, sulfur, and gas content, mainly used in the manufacture of various rotating parts; based on manufacturing processes, they are divided into standard, high-strength, and direct aging categories. Among them, high-strength and direct aging are used for high-quality GH4169 alloy forgings, with the hot deformation temperature decreasing accordingly, the average grain size of the forgings is refined sequentially, and the strength increases sequentially, meeting the application requirements of different rotating parts in aero-engines.
