Processing

Formability

The steel ingot should be homogenized before forging, and the forging heating temperature is 1100℃~1180℃.

Parts heat treatment process

1. Working at a lower temperature, the parts are required to have high tensile strength and fatigue performance, using 1080 ℃, air cooling +760 ℃, 16H, air cooling

2. When working at high temperature and requiring high thermal strength, the heat treatment specification is 1180℃, air cooling +900℃ 4H, air cooling.

Welding process

Alloys can be welded by fusion welding, diffusion welding, friction welding and other methods.
