4. Heat treatment Related
  • Annealing of 1-2344 Tool steel

At first, Slowly heated to 750-780 ℃ and allow enough times, let the steel to be thoroughly heat, Then cool slowly in the furnace. Then the 2344 tool  steel will get MAX 250 HB （Brinell hardness）.

  • Hardening of 1-2344 tool steel

1.2344 steels should be heated uniformly to 1020-1060°C. until completely heated through. And if needed, the steels can be preheated at 300-500°C (572-932°F). About 30 min per 25 mm of ruling section is to be provide and then the steels should be immediately quenche in oil or air.

  • Tempering of 1.2344 tool steel

At first, tempering of 1.2344 steels is performed at 550-650°C, Soak well at the selected temperature and soak for at least one hour per 25mm of total thickness. Then get Rockwell C hardness of 56 to 38.

Temperature [℃]       400   500     550     650

Hardness [HRc]          53      56        54       47
