HOT WORK STEEL

HOT WORK STEEL

These steels work with heat. They are recognized for great wear resistance, heat conductivity, hardness and robustness at increased temperatures. These steels have better features for use due to decreased sulphur level.

PROPERTIES & CHARACTERISTICS


  • High Mechanical Strength
  • High Polishability
  • Ductility
  • High Thermal Conductivity
  • Good Weldability

APPLICATIONS


  • Die Inserts
  • Extrusion Press Tools
  • Forming Dies
  • Mandrels
  • Hot Shear Blades
  • Rolls for Hot Rolling Machines
  • Tools for Nuts,Screws, Bolts, Rivets, Fasteners, etc
  • Forging Dies
  • Punches / Dies for Extrusion on non ferrous alloys
  • Pressure Die Casting of Aluminium Alloys
  • Moulds for Thermo plastic polymer injection with high polishability
