Product Description and Application
"GH2747" is also known as FeNicr2747, "P 747" (RU)
GH2747 (GH747) is Fe-Ni-Cr based precipitation-hardened deformation superalloy, which is used in the state of solid solution. Its long-term operating temperature is 1100°C-1250°C and short-term use temperature up to 1300°C. It has high strength, good structure stability, excellent oxidation resistance and corrosion resistance. The alloy weldability is good and various processes can be used for welding. GH2747 alloy has been used in the production of high temperature oxidation resistance components in the aerospace engine combustion chamber and afterburner, as well as in the production of various industrial furnace rolls, transmission devices, thermocouple sleeves and etc heat-resistant components, especially suitable for high-temperature anti-oxidation device parts in petrochemical, nuclear energy, metallurgy and etc fields.
