H13 (DIN 1.2344) is a hot work tool steel used in die casting molds, hot work inserts, and mold cores.
It provides good resistance to thermal fatigue and heat-related cracking, making it suitable for elevated-temperature tooling applications. H13 is typically supplied as small blocks or inserts, in pre-hardened or heat-treated condition, with processing arranged according to application requirements.
