H13
H13 is a versatile hot work tool steel known for excellent toughness and thermal fatigue resistance. It maintains strength and hardness at elevated temperatures to support stable tooling under heavy thermal cycling. The alloy offers good hardenability, allowing uniform properties in larger sections. Its balanced composition supports reliable machining and consistent heat treatment response. H13 is widely used for die casting dies, hot extrusion tooling, and forging dies. It performs well in hot shear blades, mandrels, and punches where impact resistance is critical. Built for demanding production, H13 helps extend tool life and reduce downtime.
