ALLOY625 material in China is GH625 \ NS336
Nickel-based alloy materials, high temperature and corrosion resistance.
Incone l625 Characteristics and Applications Overview:
The alloy is a solid solution strengthened nickel-based deformation high temperature alloy with molybdenum-niobium as the main reinforcing element, with excellent corrosion resistance and high oxidation properties, good tensile properties and fatigue properties from low temperatures up to 980 ℃, and resistance to stress corrosion in a salt spray atmosphere. Therefore, it can be widely used in the manufacture of aircraft engine parts, aerospace structural components and chemical equipment.

Inconel625 metallographic Organization:
The alloy in the solid solution state of the organization for the austenite matrix and a small amount of TiN, NbC, and M6C phase, after 650 ~ 900 ℃ long-term aging, the precipitation of the phase for γ ', δ, M23C6 and M6C.
Inconel625 process performance and requirements:
1, the alloy has a good cold, hot forming Performance, ingot forging heating temperature 1120 ℃.
2, the average size of the alloy's grain size and the degree of deformation of the forgings, the final forging temperature is closely related.
3, the alloy's welding performance is good, can be in the protective atmosphere with tungsten pole or the alloy as the additive for argon arc welding, can also be used for brazing connection and resistance seam welding.
4, surface treatment process: remove the alloy surface oxide skin first alkaline wash, and then in nitric acid, hydrofluoric acid - water solution pickling.
5, the alloy cold working when the amount of processing is greater than 15%, the annealing treatment should be carried out after hot working.
