Process performance and requirements of GH3170;
1.The alloy has good hot-working plasticity. In the temperature range of 1050 1150, 80% of the upsetting is allowed without cracking, the forging temperature is 1130 1150, and the final forging temperature is not less than 950.
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 plates can be connected by TIG welding and the weldability remains good in the solid solution state. After welding, stress is relieved and aging treatment is carried out.
4.The cutting performance of solid solution alloys is better than that of aging alloys.
