Grade Brief
H10 is a chromium-based hot work tool steel belonging to the AISI H-series. It combines good toughness, thermal fatigue resistance, and resistance to softening at elevated temperatures. Compared to tungsten hot work steels, H10 can achieve higher hardness after heat treatment and can be safely water-cooled in service, making it suitable for demanding hot work tooling applications.
Key Properties
- Excellent toughness compared to tungsten hot work steels.
- Resistant to softening at elevated service temperatures.
- Good thermal fatigue resistance
- Can be safely water-cooled during service.
- Capable of higher hardness than H21 or H22 tungsten grades
