Tool steels for hot work

Tool steels for hot work are alloy steels designed for tooling that operates in contact with heated metal. They are characterised by hot hardness, wear resistance, toughness and resistance to thermal fatigue, making them suitable for dies, moulds, punches and other forging, extrusion and die-casting tools.
