Uddeholm Vidar® Superior
Uddeholm Vidar Superior is a chromium-molybdenum-vanadium alloyed hot work tool steel which is characterized by:
- 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
Improved tooling performance
The name "Superior" implies that by special processing techniques and close process control, the steel attains high purity and a very fine structure. Uddeholm Vidar Superior shows significant improvements in impact toughness compared to material of the H11 (W.-Nr. 1.2343) type.
The improved impact toughness is particularly valuable for tooling subjected to high mechanical and thermal stresses, e.g. die casting dies and forging tools. In practical terms, tools may be used at somewhat higher working hardness (2 HRC) without loss of toughness. Since increased service hardness limits the formation of thermal fatigue cracks, improved tool performance can be expected.
