DIN 1.2767

Tool steel for cutting and forming tools

DIN 1.2767 is a high nickel alloy tool steel that provides excellent toughness, good hardenability and high strength even in large cross-sections. It is mainly used for forming and cutting tools where a combination of impact resistance and hardness is required. It can be hardened to a hardness of up to 55 HRC.


Alternative designation: X45NiCrMo4.3, ČSN 19655
Type: Alloy tool steel

Heat treatment:

  • Preheating: 600–850 °C (multi-stage)

  • Quenching: 830–870 °C (oil or compressed air)

  • Tempering: 540–600 °C according to the required hardness (~48–55 HRC)

  • Surface treatments: nitriding, PVD/CVD coatings possible

Forged, annealed blocks
