GH4169 is a kind of precipitation strengthened nickel-based superalloy, which has good comprehensive properties in the temperature range of -253 ~ 650℃, the yield strength below 650℃ ranks the first place in the deformation superalloy, and has good fatigue resistance, radiation resistance, oxidation resistance, corrosion resistance, good processing performance and good welding performance. It can manufacture various parts with complex shapes, and has been widely used in the above temperature range in aerospace, nuclear energy, petroleum industry and extrusion molds.
Another feature of the alloy is that the alloy structure is particularly sensitive to the hot working process, grasp the phase precipitation and dissolution law of the alloy and the relationship between the structure and the process and performance, can be formulated for different use requirements of reasonable and feasible process procedures, you can obtain various parts that can meet different strength levels and use requirements. The varieties supplied by Shanghai Bohu Group are forgings, forging rods, rolling rods, cold rolling rods, round cakes, rings, plates, belts, wires, tubes and so on. It can be made into discs, rings, blades, shafts, fasteners and elastic components, plate structural parts, cartridges and other parts for long-term use in aviation.
GH4169 Superalloy Chemical composition % :
C: ≤0.08,Cr: 17.0~21.0,Ni: 50~55.0,Co: ≤1.0,Mo: 2.80~3.30,Al: 0.30~0.70,Ti: 0.75~1.15,Fe: Bal
GH4169 Heat treatment system:
GH4169 superalloy has different heat treatment regimes to control grain size, δ phase morphology, distribution and quantity, so as to obtain different levels of mechanical properties. Alloy heat treatment system is divided into 3 categories:
I: (1010~1065)℃±10℃, 1h, oil cooling, air cooling or water cooling +720℃±5℃, 8h, furnace cooling at 50℃/h to 620℃±5℃, 8h, air cooling.
There is no δ phase in the grain boundary or in the grain, and there is notch sensitivity, but it is beneficial to improve the impact property and resist low temperature hydrogen embrittleness.
Ⅱ : (950~980)℃±10℃, 1h, oil cooled, air cooled or water cooled +720℃±5℃, 8h, furnace cooled at 50℃/h to 620℃±5℃, 8h, air cooled.
Iii: 720℃±5℃, 8h, at 50℃/h furnace cooling to 620℃±5℃, 8h, air cooling.
GH4169 Superalloy application
Manufacturing all kinds of stationary and rotating parts in aviation and aerospace engines, such as discs, rings, casings, shafts, blades, fasteners, elastic components, gas ducts, sealing components, and welded structural parts; Manufacture of various elastic elements and frames for nuclear energy industry applications; Manufacturing parts and other components for applications in the petroleum and chemical industries.
In recent years, on the basis of deepening research and expanding application of the alloy, many processes have been developed in order to improve quality and reduce cost: helium cooling process is used in vacuum arc remelting to effectively reduce niobium segregation; Using jet forming process to produce ring parts, reduce cost and shorten production cycle; Superplastic forming process is adopted to expand the production range of products.
GH4169 Superalloy function assessment:
The turbine disc, oil disc, integral rotor, shaft, fasteners and other parts made of the alloy have passed the overrotation, rupture and low cycle fatigue tests in the zero and component tests of the engine according to the model specifications used in the engine. It has passed the test of long term (life) test and test flight launch, and has met the requirements of design and application.
