Uddeholm Vidar 1 ESR
GOOD TOUGHNESS IN COMBINATION WITH VERY GOOD POLISHABILITY
Uddeholm Vida 1 ESR is a premium ESR-remelted hot work tool steel developed for demanding tooling applications where toughness, reliability, and surface quality are critical. Based on a chromium-molybdenum-vanadium alloyed composition, it combines excellent high-temperature strength with outstanding toughness and ductility, making it a trusted choice for both hot work tooling and large plastic moulds.
Benefits
- The ESR (Electro Slag Remelting) process provides a cleaner and more homogeneous steel structure, resulting in very good polishability and texturing properties, as well as consistent performance throughout the tool.
- Uddeholm Vidar 1 ESR offers good machinability, reliable through-hardening characteristics, and excellent dimensional stability during heat treatment. These properties help toolmakers achieve predictable manufacturing results and long service life in production environments.
- With its combination of strength, wear resistance, and toughness, Uddeholm Vidar 1 ESR is particularly suitable for plastic injection moulds, die-casting components, extrusion tooling, and other applications exposed to high mechanical and thermal loads. It delivers dependable performance, reduced maintenance requirements, and enhanced tool productivity.
