Bohler-Uddeholm UDDEHOLM ORVAR® SUPREME (Premium AISI H13) Hot Work Tool Steel
Categories: Metal; Ferrous Metal; Alloy Steel; Chrome-moly Steel; Tool Steel; Hot Work Steel

Material Notes: Chromium-molybdenum-vanadium alloyed steel

A premium Cr-Mo-V-alloyed hot work die steel with good resistance to thermal fatigue. The steel is produced by a special melting and refining technique in order to give mechanical properties with maximum isotropy and is certified to meet a minimum Charpy V-notch test result of 10 ft-lbs (13.6 J). Suitable for a wide variety of hot work applications, including tools for high pressure die casting, hot extrusion and press forging, ORVAR® SUPREME also meets or exceeds NADCA 207-97 specifications.

Orvar Supreme is characterized by:

  • High level of resistance to thermal shock and thermal fatigue
  • Good high-temperature strength
  • Excellent toughness and ductility in all directions
  • Good machinability and polishability
  • Excellent through-hardening properties
  • Good dimensional stability during hardening
Applications
  • Tools for die casting - Dies, Fixed inserts cores, Sprue parts, Nozzles, Ejector pins(nitrided), Plunger, shot-sleeve (normal nitrided)
  • Tool for extrusion - Dies, Backers, die-holders, liners, dummy blocks, stems
  • Tools for forging - Aluminum, magnesium, Copper alloys, Steel
