Incoloy 901（N09901）
Quantity:
Incoloy 901 Nickel-based Alloy
Data Grade: Incoloy 901
United States grade: UNS NO9901
German grade: 2.4662
1. Overview of Incoloy 901 (N09901) nickel-based alloy:
The Cr content in Incoloy 901 nickel-based alloy is usually 11.0-14.0%, and the content is 40.0-45.00%. Incoloy 901 alloy is a base alloy containing molybdenum and copper, with good thermal processing and cold processing performance. Incoloy901 is an austenitic aging hardening alloy based on Fe-43Ni-12Cr, adding titanium, aluminum and equal reinforcement elements, and contains trace amounts of boron and low carbon. It is metastable γ"[Ni3(Ti, Al] phase diffusion strengthens, and trace amounts of aluminum can inhibit the conversion of γ"to η-Ni3Ti phase. Incoloy 901 alloy has high yield strength and long-lasting strength below 650°C, has good oxidation resistance below 760°C, and has stable tissues for long-term use. . This alloy is a relatively mature alloy developed in the early stage, and is widely used to manufacture rotating discs (turbine discs, compressor discs, shaft journals, etc.) and static structural parts of aviation and ground gas turbine engines working below 650°C. Seasonal components such as turbine outer ring and fasteners.

3. Incoloy 901 (N09901) nickel-based alloy heat treatment system:
1090℃±10℃, 2~3h, water-cooled or oil-cooled +775℃±5℃, 4h, air-cooled +700~720℃, 24h, air-cooled.
4. Incoloy 901 (N09901) nickel-based alloy smelting and casting process:
The alloy is produced using a dual process of vacuum induction plus vacuum arc remelting, and can also be produced using a vacuum induction plus electroslag heavy process.
V. Application overview and special requirements of Incoloy 901 (N09901) nickel-based alloy:
This alloy is widely used in foreign countries for rotating parts and fasteners working below 650°C on aircraft engines and ground gas turbines, and has a long service life. It has also been used in aircraft engines in China and is a mature alloy that has been tested for use. If the process parameters are selected or operated incorrectly, its performance will show obvious directionality and may cause gap sensitivity, but as long as the process is strictly processed, this phenomenon will not occur. The expansion coefficient of the alloy is close to that of ferrite thermally strong alloy steel, allowing the two data to be connected to face the hot account without special regulations.
