Uddeholm Hotvar®
Uddeholm Hotvar is a high performance molybdenum-vanadium alloyed hot-work tool steel which 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
Improved tooling Performance
Uddeholm Hotvar is a specially premium hot work steel developed by Uddeholm to provide a very good performance in tooling up to 650°C. The alloy elements in Uddeholm Hotvar are balanced to give high hot wear resistance and good high temperature properties. Uddeholm Hotvar is manufactured by special techniques.
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
- roll forging, rolling segments
- rock orbital forging, punches and dies
- upset forging, clamping tools
- progressive forging, dies
- axial closed die rolling, top and bottom dies
- cross forming, segments
- hot bending, tools
- hot calibration, tools
- zinc die casting, dies
- Al-tube extrusion
Recommended hardness level is 54-58 HRC. For improving the wear resistance the tools can be plasma nitrided or nitrocarburized.
