Introduction
GH2901(GH901) is an austenitic aging lymphoma alloy based on Fe-43Ni-12Cr, with titanium, aluminum and strengthening elements added. It also contains trace amounts of boron and lower carbon. It is processed by metastable γ[Ni3(Ti, Al )] phase dispersion strengthening, and trace amounts of aluminum can inhibit the transformation of γ to eta-Ni3Ti phase. The alloy has relative turning strength and lasting strength below 650℃, good oxidation resistance below 760℃, and stable structure for long-term use. It is a relatively mature alloy developed in the early stage and is widely used in the manufacture of rotating disk parts (turbine disk, compressor disk, journal, etc.), static structural parts, and turbine outer rings of aviation and ground gas turbine engines operating below 650°C. and remaining spare parts.

Advantages
(1)High temperature strength: the material can maintain excellent mechanical properties at temperatures up to 980°C, and its yield strength and lasting strength can reach high levels at high temperatures.
(2)Oxidation resistance:GH2901 alloy contains higher chromium content， In high temperature environments, GH2901 can form a stable oxide film, effectively preventing oxides from further eroding into the alloy.
(3)Creep resistance:GH901 exhibits excellent creep resistance under high temperature and continuous load, and can maintain stable shape and size .
(4)Corrosion resistance:GH901 is especially suitable for environments with various chemical media such as acids, alkalis, and salts.
(5)Structural stability:the structure of GH2901 remains stable and is not prone to notch sensitivity
(6) Weldability:GH2901structure and performance are stable after welding
Applications
(1) Aerospace: aerospace engines, turbine blades, combustion chambers and nozzles due
(2) Chemical : reactors, heat exchangers, storage tanks, pipelines and other equipment.
(3) Oil and gas :used in the oil and gas industry to manufacture oil well equipment, oil pipelines and drilling tools.
(4) Nuclear energy :nuclear reactors, nuclear fuel elements and nuclear power plant equipment.
