Overview of GH3536 features and application fields:
This is a high-iron nickel-based high-temperature alloy mainly solid-solution-strengthened with chromium and molybdenum. It has good oxidation resistance and corrosion resistance, and has medium to high durability and creep strength below 900 ° C. Cold and hot Good formability and weldability. It is suitable for the manufacture of combustion chamber components and other high-temperature components of aero-engines. It can be used for a long time below 900°C, and the short-term working temperature can reach 1080°C.

GH3536 metallographic structure:
The structure of the alloy in the solid solution state is austenite matrix, and there are a small amount of TiN and M6C carbides.
GH3536 process performance and requirements:
1. The alloy has good cold and hot workability, and the forging heating temperature is 1170°C. 2. The average grain size of the alloy is closely related to the degree of deformation of the forging and the final forging temperature. 3. The alloy has satisfactory welding performance, and can be welded by argon arc welding, seam welding, spot welding and other methods. HGH3536 or HGH3113 welding wire is recommended for argon arc welding.
