UDDEHOLM HOTVAR® Hot Work Tool Steel

 

Subcategory: Tool Steel; Hot Work Steel; Alloy Steel; Metal

Material Notes:
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
