Uddeholm Hotvar

VERY GOOD PERFORMANCE IN TOOLING UP TO 650°C

Uddeholm Hotvar is a molybdenum-vanadium alloyed hot work tool steel.

  • Uddeholm Hotvat has very good performance in tooling up to 650°C.
  • High hot wear resistance
  • Very good temper resistance
  • High resistance to thermal fatigue ( heat checking )
  • Very good thermal conductivity
  • Suitable in applications where hot wear and plastic deformation are the dominating failure mechanisms, eg forging applications. Can be heat treated to 58HRC.
