Inconel X-750 alloy is a nickel based high-temperature alloy that has good corrosion resistance and oxidation resistance below 980 ℃, high strength below 800 ℃, good relaxation resistance below 540 ℃, as well as good formability and welding performance.
This alloy is mainly used to manufacture plane springs and coil springs with high strength and resistance to relaxation for aircraft engines operating below 800 ℃. It can also be used to manufacture parts such as turbine blades for steam turbines. The available varieties include plate, strip, bar, forging, ring parts, wire, and pipe.
1. Raw material preparation: High-purity nickel alloy is selected as the raw material, ensuring
it meets specific chemical composition and quality standards.
2. Mixing and batching: The high-purity nickel alloy is mixed with other alloying elements
according to a predetermined formula. These alloying elements may
include chromium, iron, aluminum, titanium, etc.
3. Melting: The mixed raw materials are placed in a high-temperature furnace
to melt into alloy liquid. During this process, it is ensured that
the desired chemical composition and uniform mixing are achieved.
4. Casting: The molten alloy liquid is poured into pre-designed molds to form
pipes of the required size and shape. Control at this stage is
crucial for the final product's performance.
5. Heat treatment: The cast pipes undergo heat treatment. This step aims to adjust
the grain structure and improve the mechanical properties of the
material. Common heat treatments include aging and solution
annealing.
6. Cooling and Cutting: The heat-treated pipes are cooled and then cut to the desired
lengths. It is ensured that the cutting process does not adversely
affect the properties of the pipes.
7. Surface Treatment: Necessary surface treatments such as polishing, cleaning, or other
surface coatings are performed to meet specific customer
requirements.
8. Final Inspection: Comprehensive quality inspection is conducted on the produced
Inconel X-750 alloy pipes. This includes visual inspection,
chemical composition analysis, mechanical property testing, etc.,
to ensure the product meets standard requirements.
9. Packaging and Shipping: The inspected alloy pipes are packaged to prevent damage during
transportation. Product specifications, quality certifications,
etc., are indicated, and shipping arrangements are made.
