Uddeholm Vidar 1 is a premium chromium-molybdenum-vanadium alloyed hot work tool steel developed for demanding tooling applications where a combination of toughness, heat resistance, and dimensional stability is essential. Designed to perform under severe thermal and mechanical loads, Vidar 1 is a trusted choice for manufacturers seeking long tool life and consistent production quality.

Benefits

  • One of the key advantages of Uddeholm Vidar 1 is its excellent high-temperature strength. The steel maintains its mechanical properties even at elevated operating temperatures, making it particularly suitable for hot work tooling exposed to repeated thermal cycling. In addition, its high toughness and ductility help reduce the risk of cracking and premature tool failure, even in challenging production environments.
