Formability

1. The temperature range of thermal processing is 980-1200℃, and the cooling method can be water quenching or rapid air cooling;

2. The heating temperature of steel ingot forging can be 1200°C. In order to obtain good structure and properties of the final forging or bar, the subsequent forging heating temperature should be carried out at a correspondingly lower temperature. The final forging temperature should not be lower than 950°C. The alloy should be solution treated after the severe forming process.
