Description

DIN 1.2344 tool steel Plate, Round Bar

We Supply in DIN 1.2344 tool steel round bar, flat bar, and plate with more than 16 years’ experience. 1.2344 Tool Steel/H13 steel is chromium hot work tool steels which is widely used in hot and cold work tooling applications.

Din 1.2344 Steel is a high-quality Hot work tool steel, and it belongs to the high-quality high carbon alloy tool steel. And Oil Quench & Temper Hardness is 28-34 HRC. And DIN 1.2344 steel Annealing delivery hardness less than 250HB.

DIN 1.2344 tool steel/AISI H13 steel is characterized by:

• Good resistance to abrasion at both low and high temperatures
• High toughness and ductility
• Good high-temperature strength and resistance to thermal fatigue
• Good through-hardening properties
• Small distortion during hardening
  

  1. Form of Supply

  DIN 1.2344 steel, we can supply the round bar, steel flat bar, plate, hexagonal steel bar, and steel square block. Moreover, 1.2344 steel Round bars can be sawed to your required lengths as one-offs or multiple-cut pieces. Furthermore, 1.2344 steel rectangular pieces can be saw from a flat bars or plates to your specific sizes. And Ground tool steel bar can be supplied, providing a quality precision finished bar with tight tolerances.

   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 heated, 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 the ruling section is to be provided and then the steels should be immediately quenched 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 the total thickness. Then get Rockwell C hardness of 56 to 38.
