Incoloy 901 nickel basealloys
Material Grade:incoloy 901
U.S. Grade:unsn09901
German grade: 24662
1. Overview of Incoloy 901 (N09901) nickel-based alloys:
The CR content in Incoloy 901 nickel-based alloys is typically 110-14.0% and a nickel content of 400-45.00%。Incoloy 901 alloy is a nickel-based alloy containing molybdenum and copper with very good hot and cold working properties. Incoloy901 is an austenitic age-hardening alloy based on Fe-43Ni-12Cr, adding titanium, aluminum and equal strengthening elements, and contains trace amounts of boron and low carbon, which is metastable"[Ni3(Ti, Al)] phase diffusion enhancement, trace amount of aluminum can be inhibited"Conversion to the -Ni3Ti phase.
Incoloy 901 alloy has high yield strength and lasting strength below 650, good oxidation resistance below 760, and stable structure for long-term use. This alloy is a relatively mature alloy developed in the early stage, and is widely used in the manufacture of rotating disc parts (turbine discs, compressor discs, shaft journals, etc.), static structural parts, turbine outer rings and fasteners and other parts of aviation and ground gas turbine engines working below 650.

1090 10 , 2 3h, water-cooled or oil-cooled +775 5, 4h, air-cooled +700 720, 24h, air-cooled.
4. Incoloy 901 Melting and Casting Process:
The alloy is produced by the dual process of vacuum induction plus vacuum arc remelting, and can also be produced by vacuum induction plus electroslag remelting process.
5. Incoloy 901 Application Overview and Special Requirements:
The alloy is widely used in foreign countries for aero engines and ground gas turbines to work below 650 rotating parts and fasteners, with a long service life. It has also been used in aero engines in China, and it is a mature alloy that has been tested in use. If the alloy is forged and the process parameters are not selected or operated properly, its performance will show obvious directionality and may cause notch sensitivity, but as long as the process is strict, this phenomenon will not occur. The alloy has an expansion coefficient close to that of ferritic thermally strong alloy steels, so that the two materials can be connected and there are no special regulations for the hot account.
