GB ZG26CrNiMo Heat Treatments
- Quenched and tempered (+QT1): Quenched at 970 to 960°C and Tempered at 600 to 700°C
Quenched and tempered (+QT2): Quenched at 870 to 960°C and Tempered at 600 to 680°C
Castings should be tempered twice, and the second tempering temperature should not be higher than the first tempering - Test piece 1: Normalized or quenched at 870-960°C, tempered at 600-700°C.
Test piece 2: Normalized or quenched at 870-960°C, tempered at 600-680°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.
