Heat treatment                                                                                                       

Isothermal annealing:

-   Heat to 850°Chold for 1/2 hour to 1 hour;

-          Furnace cooling to 770°C and hold at temperature for at least 10 hours;

-          Cool by 10°C /h to 720°C;

-          Cooling in air.

Stress relieving:

   To be carried out after machining and before the final heat treatment.

-          Heat to 650-700°C, hold for 4/6 hours:

-          Furnace cooling to 330-350°C;

-          Cooling in air.

Hardening:

-          Initial preheating to 350-450°C;

-          Second preheating to 750-850°Cin salt bath at 850°C;

-          Austenitizing at 960-100°C;

-          Cooling in fluid oil.

Quenched hardness: 64-65 HRC
