DIN 1.2367 Die Steel is a kind of hot work tool steel. Secondary hardening steel with high strength and wear resistance in hot. Good tempering resistance. High hardenability and toughness. Tools can be water cooled.

Dimensions
Round: dia.10-700 mm
Flat: 6-120 x 40-1200 mm
Block: 80-600 x 100-1600 mm

Delivery Condition
EAF+LF+VD+(ESR), Hot rolled or Forged, Annealed, Black surface or Machined surface, UT SEP1921 Class3 D/d

Characteristics
1. Chrome-molybdenum-vanadium steel for hardening in oil and in air with very good hardenability, high firmness during the heat and resistance to the tempering
2. Very good toughness and plastic properties during normal and also higher temperatures.
3. Very good resistance to tearing of thermal fatigue and low sensitivity to quick changes of temperature. The steel is appropriate for the heat treatment also for firmness over 1800N/mm2 and for tools cooled by water. It is well-workable during the heat and well-workable in the soft-annealed state.

Applications
1. For molds for firm and movable core parts and other parts of molds for pressure casting of aluminum alloys and large series of castings of zinc and magnesium alloys.
2. Tools for hot mechanical working, i.e. highly stressed small and middle-sized dies and inserts of dies. Dies, thorns, jaws and punches especially with the high firmness over 1800N/mm2 cooled by water.
3. Highly stressed extruders and other auxiliary tools for extrusion of non-ferrous metals during the heat, extrusion dies for aluminum and its alloys. Tools for hot cutting, e.g. small or middle-sized shear blades, trimming dies and cutting thorns.
