2. High tensile strength, fatigue strength, creep strength and breaking strength at 700 °C
3. High oxidation resistance at 1000 ° C
4. Stable chemical properties at low temperatures
5. Good welding performance Inconel 718
Chemical Composition Of Incoloy 718
Inconel718 metallographic structure:
The standard heat treatment state of the alloy consists of γ matrix γ', γ", δ, NbC phases
Inconel718 process performance and requirements:
1. Due to the high content of niobium in Inconel718 alloy, the degree of niobium segregation in the alloy is directly related to the metallurgical process.
2. In order to avoid excessive segregation of elements in the ingot, the diameter of the ingot used is not more than 508 mm.
3. The homogenized alloy has good hot workability, and the billet heating temperature of the ingot should not exceed 1120 °C.
4. The average grain size of the alloy is closely related to the degree of deformation of the forging and the final forging temperature.
5, the alloy has satisfactory welding performance, can be welded by argon arc welding, electron beam welding, seam welding, spot welding and other methods.
6, different alloy solution treatment and aging treatment process will get different material properties. Due to the low diffusion rate of the γ" phase, the Inconel 718 alloy achieves the best mechanical properties through prolonged aging treatment.

It is used to make ring parts, blades, fasteners and structural parts in aviation, aerospace and petrochemical industries. It can produce a variety of parts for petrochemical applications, which can be mass-produced and used well. The alloy can be used in the vacuum self-consumption remelting process, which can effectively reduce the segregation of antimony elements. The ring forming process can be used to produce the ring parts, which can reduce the cost and cycle. The superplastic forming can expand the production range. It is suitable for the production of ring parts, blades, fasteners and structural parts in aviation, aerospace and petrochemical industries, mainly including rods, plates, tubes, belts, wires, etc.
Inconel718 alloys are used in a wide variety of demanding applications.
