H13 is a hot work tool steel for dies and tooling that operate hot, often above 500\u00b0C.<\/p>\n      <p>Whether one can replace the other in a given part turns almost entirely on operating temperature. Use H13 when hot hardness, thermal fatigue resistance, and molten-metal erosion resistance matter.
