processing
Formability
The ingot should be homogenized before forging, and the forging heating temperature is 1100ºC~1180ºC.
Heat treatment process of parts
1. To work at a lower temperature, the parts are required to have high tensile strength and fatigue properties, using 1080°C, air cooling +760°C, 16H, air cooling
2. When working at high temperature and the material is required to have high thermal strength, the heat treatment specification is 1180 ºC, air cooling +900 ºC 4H, air cooling.
welding process
The alloy can be welded by fusion welding, diffusion welding, friction welding and other methods.
