Product Description
Seamless Pipe Dia 1-100mm GH2747 Precipitation Hardened Nickel Based Alloy
General
ЗП74 is a Fe-Ni-Cr-based precipitation hardening high-temperature alloy. It is used in a solid solution state. Its long-term operating temperature is 1100℃~1250℃, while its short-term operating temperature up to 1300℃. The alloy has high strength and good Structural stability, excellent oxidation resistance and corrosion resistance. The alloy has good welding properties and can be welded through various processes. The main products include bars, plates, pipes, wires and forgings, etc.
Application and features:
ЗП74 alloy has been used to make high-temperature anti-oxidation components 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 components. It is especially suitable for high-temperature anti-oxidation device parts in petrochemical, nuclear energy, metallurgy and other fields.
The material cost of GH2747 alloy is lower than that of the same type of high-temperature alloy. On the basis of increased chromium and aluminum content, and rare earth elements, the oxidation resistance of the alloy at 1000℃~1300℃ is greatly improved.
