DIN 1.2714/55NiCrMoV7 Hot Worked Tool Steel
Superior High-Temperature Performance
DIN 1.2714 retains 45 HRC at 650°C, offering 30% longer thermal fatigue life than H13. This makes it ideal for aluminum/zinc die-casting and hot forging dies under cyclic thermal stress.
Precision Machinability & Surface Finish
In the annealed state (≤260 HB), DIN 1.2714 exhibits excellent machinability. Its fine-grained structure allows mirror-like polishing, critical for plastic injection molds requiring high gloss.
Versatility & Cost-Effectiveness
From heavy-duty stamping tools to aerospace engine parts, DIN 1.2714 delivers reliable performance. Its cost efficiency and adaptability make it a top choice for medium-scale production and complex tooling.

Comprehensive Guide to DIN 1.2714 Hot Work Tool Steel
1. DIN 1.2714(55NiCrMoV7) steel introduction
DIN 1.2714 (56NiCrMoV7) is a high-performance hot work tool steel under the German DIN standard. With a composition of 0.50-0.60% carbon, 1.50-1.80% nickel, and 1.00-1.30% chromium, it achieves a hardness of 52-54 HRC after heat treatment. Its excellent thermal stability (retains 45 HRC at 650°C) and uniform microstructure make it ideal for hot forging dies, die-casting molds, and aerospace components. Widely used in automotive, metalworking, and heavy machinery industries, DIN 1.2714 balances durability and cost-effectiveness for high-temperature applications.

6. DIN 1.2714 Tool Steel Applications
Hot Work Tools: Hot forging dies, aluminum/zinc die-casting molds, copper alloy extrusion dies.
Industrial Tools: Hot rollers, hot punches, heavy-duty stamping dies.
Aerospace: Engine components, high-stress transmission parts.
Automotive: Crankshafts, gearbox parts, and high-temperature components.
Why Choose DIN 1.2714?
Resists oxidation and corrosion up to 650°C.
30% longer thermal fatigue life compared to H13.
Key Advantages of DIN 1.2714 Steel
High Thermal Resistance: Maintains 45 HRC at 650°C, ideal for cyclic thermal loads (e.g., die-casting molds).
Deep Hardenability: Air cooling forms martensite uniformly, suitable for large/complex tools.
Cost Efficiency: Excellent machinability in annealed state reduces processing costs for medium-batch production.
7. Features and classifications
Hot-work die divides into several main types, such as hammer forging, die forging, extrusion and die casting, including hot forging die, press machine forging die, stamping die, hot-extrusion die, metal die-casting mould. Heat distortion mould not only supports huge mechanical stress, but also thermal stress during working repeatedly. Hot-work die steel should have not only high hardness, red hardness, abrasion resistance, toughness, but also have excellent high temperature strength, thermal fatigue stability, thermal conductivity, upper harden-ability for guaranteeing the whole cross section with consistent mechanical property.
8. Delivery condition
For hot forged or hot rolled bar, usually the delivery condition is hot forged or rolled, annealed, rough turned.
For hot forged plate, usually the delivery condition is hot forged, annealed, milled surface.
For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
