High toughness combined with high working hardness, high wear resistance, extremely good caloric conductibility, good tempering properties and extremely good air hardening, water cooling possible, nitrable, good polishing qualities. Suitable for eroding. Possibly pitted by corrosion
Applicability
Hot forming tool steel for die casting, extrusion die, warm and cold shearing blades and other hot forming tools
Heat Treatment Data
Stress-relief annealing 650 - 680 °C
Soft annealing 750 - 780 °C
Hardening 1000 - 1030 °C
Quenching Oil, air or warm bath
Tempering 530 - 680 °C
Special heat treatment:
If the material is eroded or nitrified the tempering temperature has to be above
the secondary hardness maximum. A double tempering is recommendable.
