GH2696 is a nickel-based superalloy that typically has excellent mechanical properties and is suitable for applications in high temperature and corrosive environments. The following are the general mechanical properties characteristics of GH2696 superalloy:

Tensile strength: Usually at high temperatures, very high tensile strength can be achieved, generally exceeding 100 ksi (690 MPa).

Yield strength: It can maintain a certain tensile performance in a high-temperature environment.

Ductility: It usually has good ductility and is able to maintain a certain plastic deformation ability under high temperature conditions.

Fracture toughness: Usually used in high-temperature and high-stress environments, its fracture toughness is also a very important performance index.

Welding process: 1*Material Selection**: Make sure to choose a welding material that is similar or matching to GH2696 to ensure the performance and stability of the welded joint.

2.*Preheating**: When welding GH2696, it is often necessary to preheat the weld area to reduce the generation of hot cracks. The preheating temperature is generally between 300°C - 500°C.

3.*Welding Method**: Commonly used welding methods include argon arc welding, electroslag welding and plasma arc welding. Choosing the appropriate welding method can ensure the quality of the welded joints.

4.*Welding wire**: Choose the appropriate welding wire material, generally choose a nickel-based welding wire that is similar to or matched with GH2696.

5.*Welding Parameters**: Control the welding current, voltage, speed and other parameters to ensure the stability of the welding process and avoid welding defects.

6.*Post-treatment**: After the welding is completed, post-treatment processes such as heat treatment or heat treatment tempering are carried out if necessary to restore the mechanical properties and corrosion resistance of the welded joint.

Range of chemical composition:

Nickel: Approximately 55%-60%.

Chromium: Approximately 19% -22%.

Molybdenum (molybdenum): about 14% -17%.
