1.2344 H13 Hot Work Steel SKD61 8407 ESR Steel Tool and Die Flat Alloy Steel Round Bar

1.2714 (56NiCrMoV7) belongs to the German standard hot work die steel, the implementation standard: DIN 17350-1980

1.2714 (56NiCrMoV7) steel has a high Cr content and high hardenability. The martensite structure can be obtained by air cooling during quenching. After quenching and tempering, 1.2714 steel has good comprehensive properties, uniform density, high wear resistance and thermal fatigue resistance, and small deformation.

 


1.International Standard

DIN 1.2344 Hot Work Tool Steel (also known as AISI H13) is a tool steel grade standardised for hot working. The main feature of this grade is the combination of alloyed elements of Cr, Mo and V, which provides a high wear resistance to thermal shock. It is well known as for its great strength, and heat resistance. It is heavily used for die casting in the cold heading field. The presence of high vanadium in DIN 1.2344 can handle the abrasion at both low and high temperatures. It always provides a uniform and high level of machinability. This tool steel is mostly used for aluminum, magnesium and zinc die casting.

Characteristics
1. Air cooling hardened hot work tool steel, most widely used.
2. High toughness Good cold & thermal fatigue resistance.
3. Small distortion, deformation and oxide skin after heat treatment during air cooling.
4. Good resistance from the undermining of fusing Aluminum.



Applications
1. For making aluminum and copper alloy die casting mold when die cavity temperature is below 600°C
2. For making forging die, forging press mold, mold hammer block for fine forging machine uses.



Forging Technique

Heat TemperatureStart Forging TemperatureFinish Forging TemperatureCooling Method
1120-1150 °C1050-1100 °C900-850 °CPit or Sand Cooling



Heat Treatment

Annealing
750 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. 235 HB.

Hardening
1020 to 1080°C (1868 to 1976°F)
Oil, salt bath (500 - 550°C / 932-1022°F), air
Holding time after temperature equalization: 15 to 30 minutes.
Obtainable hardness:
52 - 56 HRC in oil or salt bath,
50 - 54 HRC in air.


Stress relieving
600 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.

Tempering
Slow 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.

5Feature: 

1.Vacuum degassing refining processing steel purity, suitable for polishing or etch processing plastic mold.
2. In pre-harden state delivery, no need for heat treatment can be directly used for mold processing, shorten the construction.
3. After heat treatment machining and polishing performance is good, the nitriding treatment, can be suitable for chrome plating surface treatment, such as material is the qualitative hardness is uniform (400mm thick), good toughness and good machining performance.
4.Good hardness uniformity and polishing property, good machining properties. 
5.Good integral mechanical performance under high temperatures. 
6.Good heat-resistance and fatigue-resistance.
