Summary:
GH3030 is an 80Ni-20Cr solution-strengthened superalloy with high plasticity and excellent thermal strength, and performs well below 800. The single-phase austenite structure formed by solution treatment makes it structurally stable during operation. It is suitable for the manufacture of aero engine combustion chambers and high-temperature parts with light loads below 1100. The composition of this alloy includes Ni, Cr, Ti, Al, Fe and other elements.
Introduction: GH3030 is a solution-strengthened superalloy developed in the early stage, which is widely used in the aerospace field due to its simple chemical composition and excellent performance. Below 800, the alloy exhibits excellent thermal strength and plasticity, and maintains a stable microstructure through solution treatment. It is mainly used in the manufacture of aero engine combustion chamber parts, and is suitable for various high-temperature environments.
GH3030 superalloy analysis.
Material characteristics: GH3030 has good hot and cold working performance, and can be used to make various chemical equipment and supporting accessories. Its grain size is closely related to the deformation degree of the forging and the final forging temperature. After heat treatment, the oxide scale on the surface of the part can be removed by sand blowing or pickling. Due to its zero magnetic properties, the alloy has a low oxidation rate in the air medium.
Applications: GH3030 is mainly used in the manufacture of aero engine combustion chamber components, such as combustion chamber flame cylinder, afterburner shell, adjusting sheet and other parts that work for a long time below 950. In addition, due to its excellent resistance to hot corrosion, it is suitable for working in various high-temperature environments.
