56NiCrMoV7
1.2714Heavy-duty hot work tool steel with high Ni (1.5-1.8%) for exceptional toughness at working hardness. THE forging die material for hammers and presses. Better impact resistance than H13 but lower hot hardness. Also used as backing steel for composite dies. Applications: forging dies, die holders, press tools, shear blades, and heavy-duty punches.
