Heat Treatment


ANNEALING: heat to750-800°C, with hold at minimum rate for 3 hours;
Furnace cooling.
Stress relieving:
To be carried out after machining and before the final heat treatment,
-Heating to600-650°C , for 2 hours ;
Hardening ;
-preheating to 600-700°C;
-Austenitizing at 990-1040°C;
-Cooling in fluid oil, thermal bath at 500-550°C and finally in oil,considering the steel shape and size.
Quenched hardness52-56HRC
Tempering:
To be carried out after the hardening according to the required hardness; at 170-270°C in order to match hardness and resistance to corrosion; permanence for at least 2 hours;
Tempering must be repeatedat least twice at a temperature 30°C lower than the previous. Cooling in air.
