9. Heat Treatment: Hardening&Tempering(quenched and tempered and after stress relieved)
1)Heating 30CrNiMo8 steel uniformly to 850°C;
2)W-Nr 1.6580 alloy steel should be quenched in the oil;
3)Heat the material to the temperature 550°C;
4)Soak at this temperature for at least 2 hours;
5)1.6580 alloy steel should be cooled in the furnace.
(In case after QT a straightening process is necessary then the products should be tempered and distorsion-poor annealed with at least more than 625°C.)
1)heat DIN 1.6580 steel until the temperature up to 850°C;
2)Then cool W-Nr 30CrNiMo8 steel down to the room temperature(20°C) in the air.
