The effect of the temperature realese after quenching on steel parts
The effect of the temperature realese after quenching on steel parts
(OP)
Iwould like if anyone can explain me what is the effect of
the temperature release after quenching.
Exemple :
i perform a quench of a casting or forging in the oil ?
What is the best final part temperature to extract this part :
100°C, 80°C? 50°V , RT ?
Thanks !

For most low-alloy medium carbon steels, you are probably looking at a Mf of around 200C. Going below the Mf does not do any good and only increases the likelihood of cracking.
Keep in mind that this would refer to the core temperature, not the surface temperature. But, if the steel has a Mf of 230 C and you check the surface of a 50 kilo part 5 minutes after removal of the quench and it's below 150C, you're OK.
We routinely aim for a quench exit temperature of around 175 C for a .42%c, 1%Mn, 1%Cr, .3%Mo steel. Most of these parts would crack if they were allowed to cool to below 100C.
