H-13 Tool Steel For High-Temperature Tooling
H-13 is a chromium-molybdenum-vanadium hot work tool steel designed to retain strength, toughness and wear resistance under repeated heating and cooling. It is widely used for die casting, forging, extrusion and other demanding hot-work applications.

For aluminium, magnesium and other non-ferrous die-casting applications.
Used for forging dies, inserts, punches and related hot-working tools.
Suitable for aluminium extrusion dies, backers and associated tooling.
Used where cutting tools experience elevated operating temperatures.
Suitable for punches and tooling exposed to high thermal and mechanical loads.
Can also be used for selected moulding applications requiring toughness and thermal stability.
H-13 is normally preheated and austenitized before air cooling, followed by tempering to achieve the required balance of hardness and toughness.
Controlled preheating helps reduce thermal stress before the final hardening temperature is reached.
The steel is heated to the appropriate austenitizing temperature and then air quenched.
Tempering is performed after hardening to develop the required combination of hardness, toughness and thermal stability.
Double tempering is commonly used for H13 tooling to improve stability and achieve consistent final properties.
