EXCELLENT THROUGH HARDENING PROPERTIES

uddeholm_hot-work_extrusionjpg

Uddeholm Orvar 2 Microdized is a premium hot work tool steel engineered for demanding applications where high-temperature strength, wear resistance, and dimensional stability are critical. With its exceptional through-hardening properties and uniform microstructure, this steel delivers consistent performance across a wide range of tooling environments.

Benefits

  • Designed to meet the rigorous standards of aluminum extrusion tooling and die casting, Uddeholm Orvar 2 Microdized offers outstanding resistance to thermal fatigue, plastic deformation, and premature cracking.
  • Thanks to its high level of machinability and polishability, manufacturers benefit from reduced production time and enhanced surface finishes.
  • The material’s availability in large round dimensions further supports versatility in design and tooling applications.

In east/south east asian countries served by Assab, Uddeholm Orvar 2 Microdized is sold as AS 8407 2M.
