Heat Treatment Process
Hardening: Heat the steel evenly to 930~980°C until the whole section reaches temperature. Then quench in oil to cool.
Annealing: Heat the steel to 800~840°C, hold it well at temperature, and then let it cool slowly inside the furnace.
Tempering: Heat the steel uniformly, hold it at the selected tempering temperature, and then allow it to cool in still air.
| Tempering Temperature℃ | 180 | 480 | 550 | 600 |
| Hardness (HRC) | 63 | 58 | 53 | 40.0 |
