EDRO S7 ESR

EDRO S7 ESR is a chromium-molybdenum shock resistant steel characterized by high toughness and high impact resistance.

These benefits, coupled with the high wear resistance offer the molder low-maintenance, long-life molds for the greatest overall molding economy.

EDRO S7 ESR is produced using the ElectroSlag-Refining (ESR) technique, resulting in an extremely fine and consistent micro-structure with superior cleanliness.

  • High toughness
  • Good wear resistance
  • High impact resistance
  • Good through hardening properties
  • Good machinability
  • Good dimensional stability during hardening
