Overview of characteristics and application fields of Inconel600;
The alloy is a Ni-Cr-Fe-based solid solution strengthening alloy, which has good high-temperature corrosion resistance and oxidation resistance, excellent cold and hot working and welding performance, and satisfactory thermal strength and high plasticity below 700℃. The alloy can be cold-worked and strengthened, and can also be connected by resistance welding, solution welding or brazing. It is suitable for manufacturing low-load antioxidant parts below 1 100℃.

Composition and properties of inconel600
Inconel600 standard
Metallographic structure of Inconel600:
After the alloy was treated at 1 120℃ for 2 hours, only tin nitride and Cr7C3 carbide were found. After long-term aging at1500℃ and 870℃, the microstructure of the alloy is still Cr7C3 and TiN, which indicates that the structure of the alloy is stable.
Technological properties and requirements of Cr-Ni-Fe alloy 600;
1. The alloy has good hot workability, and the heating temperature for ingot forging is110℃ ~1140℃.
2. The average grain size of the alloy is closely related to the deformation degree of forgings and the final forging temperature. 3. The alloy has good weldability and can be connected by arc welding, argon arc welding, resistance welding, brazing and other methods. After solution welding, large or complex welded structural parts should be annealed at 870℃ for 65438±0h to eliminate welding stress. 4. The alloy must be machined after heat treatment. Because of the work hardening of materials, it is suggested to use a lower cutting speed and re-feeding tool than low-alloy standard austenitic stainless steel before processing into a surface layer that has been cold hardened.

Metallographic structure of Inconel625 alloy;
The microstructure of solid solution alloy is austenite matrix and a small amount of TiN, NbC and M6C phases. After long-term aging at 650~900℃, the precipitated phases are γ′, δ, M23C6 and M6C.
Process performance and requirements of Inconel625;
1. The alloy has good cold and hot formability, and the heating temperature for ingot forging is 1 120℃.
2. The average grain size of the alloy is closely related to the deformation degree of forgings and the final forging temperature.
3. The alloy has good weldability, and can be welded by TIG welding or the alloy as filler in a protective atmosphere, or by brazing and resistance seam welding.
4. Surface treatment process: When removing the oxide scale on the alloy surface, wash it with alkali first, and then wash it with nitric acid and hydrofluoric acid-water solution.
5. When the processing capacity of the alloy is greater than 15% during cold working, it should be annealed after hot working.
