DIN 1.2767 ESR

High-toughness tool steel with excellent cleanliness and stability

DIN 1.2767 ESR is an electroslag remelted (ESR) version of the alloy tool steel 1.2767. Thanks to the ESR process, it has significantly higher purity, finer structure, better polishability and higher impact strength than the standard version. It is used in demanding applications requiring a combination of strength, toughness and surface quality, for example in molds, dies or cutting tools.


Alternative designation: X45NiCrMo4 ESR
Type: Alloy, tool steel (ESR), heat-treatable 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)

  • Possibility of nitriding or PVD treatment to increase service life

Forged, annealed blocks

Features:

  • High toughness and strength even in larger dimensions

  • Excellent purity thanks to ESR – fewer inclusions, finer structure

  • Excellent dimensional stability and crack resistance

  • Hardness after hardening up to approx. 55 HRC

  • Easily sandable and polishable – suitable for molds with demanding surface finishes

  • Suitable for nitriding or coating (e.g. PVD)

Use:

  • High-stress cutting and forming tools

  • Dies and tools for hot and cold forming

  • Molds for pressure casting and plastic injection

  • Precision tools, dies and shaped parts requiring high gloss

  • Mechanically stressed parts with high requirements for toughness and stability (gears, pins, shafts)
