Uddeholm Vidar Superior
DEVELOPED TO BE TOUGH
Uddeholm Vidar Superior is developed to be tough. With its superior toughness Uddeholm Vidar Superior is a great steel for the largest die casting dies where the safety of great cracking resistance is of the highest priority. The improved toughness makes it a suitable steel in tooling subjected to high mechanical and thermal stresses.
- High level of resistance to thermal shock and thermal fatigue
- Good high-temperature strength
- Excellent toughness and ductility in all directions
- Excellent through-hardening properties
- Good dimensional stability during hardening.
- Hot wear resistance 40%
