Heat Treatment

Isothermal annealing:
Heat to 850÷880℃;
Funace cooling to 770℃ and hold at temperature for at least 10 hours;
Cool by10℃/h to 720℃;
Cooling in air.

Stress relieving :
To be carried out after machining and befor the final heat trestment,
-Heat to 650÷700℃ , hold for 4/6 hours ;
-Furnace cooling to 330÷350℃
-Cooling in air
Hardening :
-Initial preheating to 350÷450℃;
-Second preheating to 750÷850℃ in sait bath at 850℃;
-Austenitizing at 960÷100℃;
-Cooling in air or in oil if large parts.
Quenched hardness:64÷65HRC
Tempering:
In the temperature range 150÷300℃ with minimum holding time 3h. For parts hardened at 1080÷1100℃, a first will be carried out at 500÷550℃ in order to expioit secondary handness, foliowed by a second tempering at 180/300℃
