Excellent Quality Nickel-Based Alloy Inconel 718 Pipe/Tube

The Inconel 718 is mainly γ '[ Ni3(Al, Ti, Nb)] Nickel based high temperature alloys with aging reinforcement have good corrosion resistance and oxidation performance below 980 °C, high strength below 800 °C, and good relaxation resistance below 540 °C. It also has good forming and welding properties, The alloy is mainly used to manufacture components such as corrosion-resistant ring parts, structural parts and bolts that work below 800 °C and require higher strength, and flat Springs with medium or low stress that work below 540 °C and require relaxation resistance. And spiral Springs. It can also be used to make parts such as turbine blades.

Inconel X-750 process performance and requirements:

1.Due to the high content of niobium in the Inconel 718 alloy, the degree of niobium segregation in the alloy is directly related to the gold treatment process.

2.In order to avoid heavy segregation of elements in the ingot, the diameter of the ingot used is not more than 508mm.

3.The alloy treated by homogenization has good thermal processing performance, steel ingot open heating temperature must not exceed 1120 °C.

4.The average grain size of the alloy is closely related to the deformation degree and final forging temperature.

5.The alloy has satisfactory welding performance, can be welding argon arc welding, electron beam welding, welding, spot welding and other methods.

6.The alloy different solid solution treatment and aging process will get different material properties. Due to the low diffusion rate of the γ "phase, the best mechanical performance of the Inconel 718 alloy can be achieved through long-term aging.
