Product Description
H13 ESR 1.2344 EAF Flat bar and round bar forge block hot rolled flat
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.

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.
7. Pre-hardened to HRC30-36 can be directly used for mold processing, shorten the construction period.
