DIN 1.2714

High-strength die steel for hot forming

DIN 1.2714 is an alloyed tool steel suitable for dies and tools exposed to shock and thermal stress. Due to its chemical composition with a higher nickel and molybdenum content, it has excellent toughness even at larger cross-sections. It is mainly used in the production of large-sized dies, cutting tools and tools for hot forging.


Alternative designation: 56NiCrMoV7, ČSN 19663
Type: tool steel / die steel

Heat treatment:

  • Preheat: 600–850 °C

  • Hardening: 850–880 °C (oil or air for smaller parts)

  • Tempering: 500–650 °C depending on the required hardness

  • Nitriding or coating possible to increase service life

Round bars, rolled, forged, annealed
