GH2747 is an iron-nickel-chromium-based precipitation hardening high-temperature alloy. It is used in a solid solution state. Its long-term operating temperature is 1100~1250°C, and its short-term operating temperature can reach 1300°C. The alloy has high strength and good structural stability, and has excellent oxidation resistance and corrosion resistance. The alloy has good welding properties and can be welded using various processes. Suzhou Xunshi New Materials can provide GH2747 plates, bars, seamless pipes, wires and forgings and other products, and can also negotiate and customize other products according to customer requirements.
Product application overview and characteristics
The alloy has been used to make high-temperature anti-oxidation parts in aviation and aerospace engine combustion chambers and afterburners. It is also used to make various industrial furnace rollers, transmission devices, thermocouple sleeves and other heat-resistant parts. It is especially suitable for high-temperature anti-oxidation devices in petrochemical, nuclear energy, metallurgy and other fields. The cost of the alloy is lower than that of high-temperature alloys of the same type. On the basis of increasing the chromium content of the alloy, by increasing the content of aluminum and adding trace amounts of rare earth elements, the oxidation resistance of the alloy at 1000°C~1300°C is greatly improved.
