H13 or 1.2344 hot work tool steels have good tempering resistance, high temperature wear resistance, good quenching and heat resistance impact resistance, high strength, high toughness, good thermal cracking resistance. It can be nitrided to increase wear resistance.
It is used for making extrusion mold and casting mold of aluminum-magnesium alloy, zinc alloy and copper alloy. It is also can used for making hot pressing mold and so on.
