H13 Hot Work Tool Steel
Versatile chromium-molybdenum-vanadium hot work tool steel with excellent thermal shock resistance.
H13: Superior Performance at High Temperatures
AISI H13 is the most popular hot work tool steel. It features a good balance of toughness, heat check resistance, and high-temperature strength. It resists softening even after prolonged exposure to high temperatures.
Key Features & Properties
- Hot Hardness: Retains hardness at elevated temperatures.
- Thermal Fatigue: Excellent resistance to thermal cracking (heat checking).
- Toughness: High toughness and ductility.
- Machinability: Good machinability and polishability.
Typical Applications
- Aluminum and zinc die casting dies
- Extrusion dies and mandrels
- Forging dies and inserts
- Hot shear blades
Technical Specifications
H13 is widely used for pressure die casting tools, extrusion tools, and forging dies. It can be water cooled in service.
