UDDEHOLM ORVAR® SUPERIOR (Premium AISI H13) Hot Work Tool Steel

 

Subcategory: Tool Steel; Chrome-moly Steel; Hot Work Steel; Alloy Steel; Metal

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® Superior meets or exceeds the NADCA 207-97 and the 207-2003 Superior Specification in dimensions up to 18” in thickness.

Orvar Superior is characterized by:

  • A 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
