GH3625 high-temperature alloy is suitable for aerospace industry strip description

GNEE GH3625 high-temperature alloy is suitable for aerospace industry strip materials
GH3625 is a nickel-based superalloy coil widely used in the aerospace industry due to its excellent high-temperature strength, creep resistance, and oxidation resistance. Its main characteristics include high strength and corrosion resistance, but its high alloying degree makes deformation difficult. GH3625 coils are used to manufacture engine casings, guide vanes, and fuel manifolds, and processing methods include hot stamping, which requires precise control of temperature and time to optimize the microstructure.

FAQ
Q:What are the advantages of GH3625 over standard stainless steel in high-temperature applications?
A: GH3625 is a nickel-based alloy with significantly superior oxidation resistance and high-temperature (up to 1050°C) strength retention compared to ordinary stainless steel, while most stainless steels experience performance degradation above 800°C. Furthermore, GH3625 is less prone to oxidation and deformation during thermal cycling.
Q:Can GH2302 and Inconel 718 be used as alternatives to GH3625?
A: Each alloy has its specific applications. GH2302 offers good value for money and excellent high-temperature oxidation resistance; while Inconel 718 exhibits superior strength under creep conditions. When surface finish and oxidation stability are critical, GH3625 is the better choice.
Q:How long does it take to deliver OEM-customized GH3625 coils?
A: Delivery time depends on quantity and specifications. Standard-sized coils can be delivered within 7-12 business days. Custom width and edge treatment can take 2-4 weeks, including quality inspection and export preparation time.
