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
