The final heat treatment of HG785D steel plate is quenching and high temperature tempering (quenching and tempering). Alloy quenched and tempered steel has higher hardenability, and generally uses oil. When the hardenability is particularly large, it can even be air cooled, which can reduce heat treatment defects. The ultimate performance of alloy quenched and tempered steel depends on the tempering temperature. Tempering at 500 ℃ -650 ℃ is generally used. By selecting the tempering temperature, the required performance can be obtained. In order to prevent the second type of tempering and brittleness, it will be cooled quickly (water-cooled or oil-cooled) after tempering, which is conducive to the improvement of toughness.
