| Molybdenum-vanadium alloyed steel Hotvar® is a premium hot work steel developed by Uddeholm to provide very good performance in tooling up to 1200°F (650°C). The alloying elements in Hotvar® are balanced to give high hot wear resistance and good high temperature properties. Manufactured by special techniques, Hotvar® is suitable for applications where hot wear and/or plastic deformation are the dominating failure mechanisms. Hotvar is characterized by: - High hot wear resistance
- Very good high temperature properties
- High resistance to thermal fatigue
- Very good temper resistance
- Very good thermal conductivity
Applications: Uddeholm Hotvar is a hot-work tool steel suitable for applications where hot wear and/or plastic deformation are the dominating failure mechanisms. Applications and tools of especial interest:- Warm forging, dies and punches
