Heat Treatment Process
Hardening: Heat the steel evenly to 980~1010°C until the whole section reaches temperature. Then quench in oil to cool.
Annealing: Heat the steel to 800~830°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 (℃) | 100 | 200 | 300 | 400 |
| Hardness (HRC) | 63 | 61 | 60 | 58.0 |
Application Fields
