INDUSTRIAL EQUIVALENT GRADES

technical specification


Hot Work Steels contain Chromium, Tungsten and Molybdenum. Their properties are matched specifically to high temperature applications. They are used for hotwork tools, die casting tools, extrusion tools, etc.

APPLICATION

  • Turning tools
  • Slotting tools
  • Twist drills
  • Saws
  • Chasers
  • Broaching tools
  • Cold extrusion dies
  • Tool bits
  • Planning tools
  • Taps
  • Lathe tools
  • Hobs
  • Profile cutting tools
  • Reamers
  • Punches

QUALITIES

In today's industrial applications the quality and variation of high performance tool steels show an increase in hot work applications new generation hot work steels which are produced by ESR, VAR processes. Going with the trend of the industry we offer hot work steel in three separate categories as per preference of customers.


  • Good Abrasions resistance is required for checking satisfactory tool life.
  • The high working temperature put very high demands on the tool steel. The properties' profile of material used for hot work should include an excellent hot strength as well as a very good ductility and toughness.
  • High Temperature dimensional stability.
