Summarize:

1. The thickness of 18 is waiting for the customer to confirm the standard, whether to modify the mold or process

2. Before processing, it is necessary to detect the hardness of the body, stretch the test rod, and confirm that it is

qualified before processing

3. Castings are tested for Brinell hardness according to ISO 6506-1, and the control range is above 85HB

4. The castings have been inspected by radiographs and conform to the third-level standard of
