Uddeholm Vidar Superior

detalhe

Description

Electro Slag Remelted (ESR) steel which belongs to a new generation of modified steels with a low content of silicon. Produced using the latest and most advanced manufacturing techniques featuring high toughness. Tested and certified, ensuring the best possible tool performance, it is indicated in applications where toughness is extreme, such as aluminium die casting or forging. The high purity of the metal structure makes it equally excellent in plastic injection moulds.

Main applications

  • Plastic injection mouls
  • Suitable for large moulding areas with high surface finishing requirements (automotive optics)
