Alloy Steel with 1.2367 Wear Resistant Hot Work Die Steel Plate Metal Sheet Pipe Bar

Alloy Steel with 1.2367 Wear Resistant Hot Work Die Steel Plate Metal Sheet Pipe Bar


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 mmFlat: 6-120 x 40-1200 mmBlock: 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


Chemical Composition(%)

Steel Grade C Si Mn P S Cr Mo V

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 tempering2. 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.


Heat Treatment
Annealing750 to 800°C (1382 to 1472°F)Slow controlled cooling in furnace at a rate of 10 to 20°C/hr (50 to 68°F/hr) down to approx. 600°C (1112°F), further cooling in air. Hardness after annealing: max. 229 HB.Stress relieving600 to 650°C (1112 to 1202°F)Slow cooling in furnace; intended to relieve stresses set up by extensive machining, or in complex shapes. After through heating, hold in neutral atmosphere for 1 - 2 hours.Hardening1030 to 1080°C (1886 to 1976°F)Oil, salt bath (500 - 550°C / 932-1022°F), airHolding time after temperature equalization: 15 to 30 minutes.Obtainable hardness:52 - 56 HRC in oil or salt bath,50 - 54 HRC in air.TemperingSlow heating to tempering temperature immediately after hardening / time in furnace 1 hour for each 20 mm of work piece thickness, but at least 2 hours / cooling in air. It is recommended to temper at least twice.A third tempering cycle for the purpose of stress relieving may be advantageous.1st tempering approx. 30°C (86°F) above maximum secondary hardness.2nd tempering to desired working hardness.The tempering chart shows average tempered hardness values.3rd for stress relieving at a temperature 30 - 50°C (86 to 122°F) be low highest tempering temperature.
