What is inconel 901 Alloy?
Inconel 901 Alloy nickel-iron-chromium alloy containing titanium and aluminum for precipitation hardening and molybdenum for solid-solution strengthening. The alloy has high yield strength and creep resistance at temperatures to about 1110°F (600°C). A substantial iron content enables the alloy to combine high strength with good forging characteristics. Used in gas turbines for discs and shafts. Standard products form is round.

Where Inconel 901 Alloy can be used?
The alloy is used for components in aircraft and gas turbines, such as turbine rotors, compressor discs, hubs and shafts, with a maximum service temperature around 1100ºF (595ºC).
Why choose inconel 901 Alloy?
Alloy 901 has good corrosion resistance to the atmospheres normally found in jet engine operations. It has slightly lower scaling resistance than such alloy as Types 309 and 310 stainless steel.
How to heat-treat inconel 901 Alloy?
1.Solution Treatment: 1975/2025°F (1080/1107°C), hold 2 hours at heat, and water quench.
2.Stabiliztion Treatment: 1400/1475°F (760/802°C), hold 2 to 4 hrs, and air cool.
3.Precipitation Hardening Treatment:1300/1375°F (704/746°C), hold for 24 hours, and air cool.
How about Mechanical Properties of Inconel 901 Alloy?
901 bar is to ordered to AMS 5660 is supplied either solution annealed or solution annealed and aged, and may be machined in either condition. Good results are often obtained by rough machining in the solution annealed condition and finishing after heat treatment. Carbide tooling generally produces the highest cutting rates and is recommended for most turning operations involving uninterrupted cuts. High speed steel tools may be used for interrupted cuts, finishing to close tolerances and cutting with the least amount of cold work hardening. Care must be taken to ensure that a positive cutting action is achieved at all times, otherwise glazing (work hardening) will occur which will inhibit further machining.
Is Inconel 901 Alloy Weldable?
Alloy 901 can be welded by the inert-gas-arc method. It is difficult to weld. All welding should be done in the solution treated condition. Cold worked parts should be re-solution treated before welding. A re-solution treatment is recommended after welding before stabilizing and aging.
