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.

Ledeburitic 12% chrome steel, excellent wear resistance due to the high volume of hard carbides in the steel matrix, high surface hardness after heat treatment, medium toughness, dimensionally stable, high compressive strength, not secondary hardenable. Similar to AISI D6

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.

1.2343 die steel belongs to electroslag remelting hot-work die steel. It has uniform material and superior machinability and polishability, good high toughness and high plasticity, high wear resistance at high and low temperatures, and overall hardening performance.
