Product brief introduction
The steel after quenching, low temperature tempering has good comprehensive mechanical properties, good low temperature impact toughness, temper brittleness is not obvious. The grain size of steel grows when carburizing, so it requires secondary quenching in order to improve the toughness of the heart and it is not suitable for cooling and quenching.
