SF 2000 / AISI P20 / DIN 1.2738
  • Hardness of 31-34 HRC
  • Improved pre-hardened mold steel grade specially designed for large plastic moulds. It has higher impact strength and good temper resistance.
  • Forged on a 5000 ton press equipped with wide dies assuring maximum deformation during forging process.
  • Forged using a special densifying process which assures optimum consolidation of centers.
