GB ZG23Cr12MoV Heat Treatments
- Quenched and tempered (+QT): Quenched at 1030 to 1080°C and Tempered at 700 to 750°C
- Normalized or quenched at 1030-1080°C; Tempered at 700-750°C.
The holding time for normalizing or quenching heating should be calculated based on the maximum wall thickness of the casting loaded in the furnace. When the thickness is less than or equal to 25 mm, the holding time shall not be less than 1 hour. For every 25 mm increase in wall thickness, the holding time shall increase by 1 hour.
