GH3030 alloy material
GH3030 alloy material is a Ni-Cr-based solid solution strengthened and deformed high-temperature alloy with a service temperature below 800°C. The alloy has good thermal strength, high plasticity, resistance to cold and thermal fatigue and oxidation properties, and has good cold stamping and welding process properties. The alloy becomes single-phase austenite after solid solution treatment, and its structure is stable during use. It is mainly used for turbine engine combustion chamber parts that work below 800°C, and for high-temperature parts below 1100°C that require oxidation resistance but bear small loads. The main products are cold-rolled plates, bars, rings, wires and pipes. GH3030 alloy materials have been used to manufacture aero-engine combustion chambers, afterburners and casing mounting edges. GH3030 alloy material has excellent welding performance and can be welded by argon arc welding, spot welding, seam welding or brazing. If the solid solution temperature is low during production, the old grain boundaries formed by residual carbides will be retained.
GH3030 is a high-temperature alloy and is a nickel-based high-temperature alloy. It is also known as Alloy 3030 or Inconel 3030. The alloy is primarily composed of nickel (approximately 55%), chromium (approximately 19%) and iron (approximately 18%), with smaller amounts of other elements such as cobalt, molybdenum and aluminum.
GH3030 has excellent high temperature strength, oxidation resistance and creep resistance, making it suitable for applications in extreme environments. It is particularly useful in industries such as aerospace, gas turbines, chemical processing and nuclear reactors. The alloy maintains its mechanical properties at high temperatures and shows good corrosion resistance in various corrosive media.
