DIN 1.2714 Hot Work Tool Steel: Properties, Applications, and Processing
When Heat and Impact Collide - You Need a Steel That Can Handle Both
In high-temperature, high-pressure industrial environments - forging, die casting, hot cutting -failures aren't an option. You need a material that’s built to last, built to perform.
That’s where DIN 1.2714 shines.
Known for its unbeatable combination of toughness, wear resistance, and thermal resilience, DIN 1.2714 is one of the most trusted hot work tool steels used in demanding applications worldwide.
Properties of DIN 1.2714 Steel
Chemical Composition
The chemical composition of DIN 1.2714 steel plays a crucial role in determining its performance characteristics:
| Element | Composition (%) |
|---|---|
| Carbon (C) | 0.55 |
| Silicon (Si) | 0.3 |
| Manganese (Mn) | 0.9 |
| Nickel (Ni) | 1.7 |
| Chromium (Cr) | 1.1 |
| Molybdenum (Mo) | 0.5 |
| Vanadium (V) | 0.1 |
| Phosphorus (P) | 0.015 (max) |
| Sulfur (S) | 0.002 (max) |
This composition ensures high hardenability, excellent toughness, and superior wear resistance.
Mechanical Properties
DIN 1.2714 steel is typically supplied quenched and tempered, achieving the following mechanical properties:
| Property | Value |
|---|---|
| Hardness | 37–41 HRC (pre-hardened) |
| Yield Strength (Rp0.2) | 1045 MPa |
| Tensile Strength (Rm) | 1000-1400 MPa |
| Elongation | 15-20% |
| Impact Toughness | 20-25 J/cm² |
| Elastic Modulus | 205 GPa |
Applications of DIN 1.2714 Steel
DIN 1.2714 is a versatile material used in:
- Hot forging dies
- Die holders and inserts
- Hot cutting blades and punching tools
- Plastic injection mold cores and cavities
- Large-scale molds requiring high surface finishes
- Compression dies for thermoplastics and thermosetting materials
The steel's high toughness and wear resistance make it ideal for applications that involve high mechanical and thermal stress.
Heat Treatment and Processing
Hardening
- Heat to 870°C (1600°F) and hold for 1 hour per inch of thickness.
- Ensure protective measures to prevent oxidation and decarburization.
- Cool using oil, air, or high-velocity gas depending on the required hardness and component thickness.
Tempering
- Temper immediately after cooling when the temperature reaches 50–80°C (120–180°F).
- Maintain one hour per inch of thickness at the tempering temperature.
- Double tempering is recommended with cooling to room temperature in between.
- Proper tempering enhances mechanical properties and prevents stress-induced cracks.
Continuous Cooling Transformation (CCT) and Tempering Curve:
- The CCT diagram helps in selecting optimal cooling rates to achieve desired microstructures.
- Tempering curves determine mechanical properties at different tempering temperatures.
Metallurgical and Physical Properties
DIN 1.2714 offers superior metallurgical characteristics:
- Uniform grain structure (ASTM E112 method)
- Low non-metallic inclusion content (ASTM E45A)
- Guaranteed hardness dispersion (less than 30 HB across thickness)
| Physical Property | Value |
|---|---|
| Thermal Conductivity | 29 W/mK |
| Coefficient of Thermal Expansion (20–400°C) | 11.9–13.4 × 10⁻⁶/K |
| Specific Heat Capacity | 460 J/kgK |
Surface Treatments
DIN 1.2714 steel is highly suitable for various surface treatments, improving its longevity and performance:
- Chemical Etching: Ensures consistent pattern reproduction for texturing applications.
- Electro Discharge Machining (EDM): Recommended for intricate machining, with removal of hardened white layers post-processing.
- Chrome/Nickel Plating & Nitriding: Enhances surface hardness and corrosion resistance.
- Polishing: Avoid excessive polishing pressure to prevent defects such as orange peel and ripples.
