Heat Treatment Process

Hardening: Heat the steel evenly to 930~1970°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.
