HOT WORK TOOL STEEL

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 45 HRC. And DIN 1.2344 steel Annealing delivery hardness less than 250HB.

Hot work tools made of H13 material can be safely water cooled in hot work use where thermal shock cracking is not an issue. Its resistance to thermal fatigue, erosion, and wear makes it the mold material of choice for aluminum and magnesium die castings, as well as many other hot working applications. However, H13 metal is subject to hydrogen embrittlement and can be nitrided for additional wear resistance.

Large die casting tools, tools needing high strength at elevated temperatures, forging dies, mandrels, extrusion dies.

55NiCrMoV7/1.2714 is an Ni alloyed die steel which has extreme toughness and good through hardening properties with very little size change after heat treatment.55NiCrMoV7/1.2714 is similar to AISI/SAE L6,and is used for making forging dies,hot shear knives,punches,backing plate,die holders,hot punching tools

The application of steel 1.2343 ESU (X37CrMoV5-1) is die casting molds for light metal processing, cylinders and pistons on cold chamber machines, metal extrusion tools, etc.

H-11 hot work tool steel is recommended for hot tooling applications where maximum resistance to cracking is required. Such applications include hot punches, die casting dies, forging dies, hot shear blades, hot gripper dies, and extrusion tooling.

1.2344 has good comprehensive performance at medium temperature (~600°), high hardenability (that can be hardened in the air), low heat treatment deformation rate, and its performance and service life are higher than 1.2581
1.2344can be used for forging hammer forging dies, aluminum alloy die-casting dies, hot extrusion dies, high-speed precision forging dies and forging press dies, etc.

DIN 1.2367 ESR is a chromium-molybdenum-vanadium alloyed hot work tool steel with high
thermal fatigue resistance. It has been refined via ESR process to ensure highest quality standards in terms of grain
size, segregation, micro-cleanliness, and purity. EN DIN 1.2367 features high isotropy, reason for which transversal
resilience is often three times higher when compared to conventional EN DIN 1.2367. Furthermore, the thermal
fatigue resistance is also often much higher than that of conventional hot work tool steel EN DIN 1.2343, enabling
longer die lifetime.

Tungsten hot work tool steels are of different types, namely, H21 to H26 types. These hot work tool steel have similar characteristics to that of high speed tool steel. The primary alloying elements in tungsten hot work tool steel include tungsten, chromium, carbon, and vanadium. They are resistant to distortion when they are air hardened, and have higher hardening temperature when compared to chromium hot work tool steel. Breakage of the tungsten hot work tool steel can be reduced if they are preheated to operating temperature before use. Thermal shock resistance and toughness of these hot work tool steel can be improved by reducing the carbon content.
