GH3044 is a solid solution strengthened nickel-based alloy designed to maintain excellent performance in high temperature environments below 900°C. The alloy has the following main characteristics:
High temperature performance: GH3044 has high plasticity and medium thermal strength below 900°C, while showing excellent oxidation resistance and corrosion resistance. These characteristics make it an ideal choice for manufacturing high temperature components.
Chemical composition: The main components of the alloy include nickel (Ni), chromium (Cr), tungsten (W), molybdenum (Mo), titanium (Ti) and aluminum (Al). Nickel, as a matrix element, gives the alloy excellent oxidation resistance and corrosion resistance; chromium forms a dense chromium oxide protective film at high temperature to improve oxidation resistance and corrosion resistance; tungsten and molybdenum improve the high temperature strength and creep resistance of the alloy through solid solution strengthening; titanium and aluminum form γ' phase, further enhancing the high temperature strength and fatigue resistance of the alloy.
Application areas: GH3044 is widely used in aerospace, energy, chemical industry and other fields. Especially in the main combustion chamber and afterburner of aircraft engines, it is used to manufacture key components such as heat shields, guide vanes, mounting edges, and ducts. These components need to withstand stress and corrosion for a long time at high temperatures, and the excellent performance of GH3044 makes it an ideal choice.
Processing performance: GH3044 has good processing and forming performance and can be processed and formed by various processes such as hot pressing, powder metallurgy, hot rolling, hot stretching, and forging. In addition, the alloy also has good welding performance and can be connected and repaired by argon arc welding, spot welding, seam welding, and brazing.
