International Mold Steel Premium H13 Hot Work Die and Mold Steel Product Information -:- For detailed product information, please contact sales. -: # **Product Introduction: Premium H13 Hot Work Die and Mold Steel** ## **1. Overview** **Premium H13** represents the highest quality tier of **chromium-molybdenum-vanadium hot work tool steel**, manufactured to exacting standards for the most demanding die and mold applications. This enhanced variant of standard AISI H13 (DIN 1.2344) is produced using advanced metallurgical processes such as **Electro-Slag Remelting (ESR)** or **Vacuum Arc Remelting (VAR)** to achieve exceptional **microstructural homogeneity, purity, and isotropic properties**. Designed for applications requiring superior **thermal fatigue resistance, high-temperature strength, toughness, and polishability**, Premium H13 is the material of choice for critical tooling in die casting, hot forging, and high-performance plastic injection molding where tool longevity and reliability are paramount. ## **2. International Standards & Specifications** Premium H13 meets and exceeds the requirements of all major international standards for H13-type tool steels, with additional quality guarantees. * **Primary Standards (Base Grade):** * **AISI H13 (UNS T20813):** American Iron and Steel Institute designation. * **DIN 1.2344 (X40CrMoV5-1):** German standard, the most widely recognized specification. * **JIS G4404 SKD61:** Japanese Industrial Standard. * **ISO 4957 X40CrMoV5-1:** International Standardization Organization classification. * **Quality Designations for Premium Grade:** * **ESR (Electro-Slag Remelted):** Indicates secondary refining for superior cleanliness and homogeneity. * **VAR (Vacuum Arc Remelted):** Indicates vacuum remelting for ultra-high purity. * **ISOPUR® / ISODISC®:** Manufacturer-specific trademarks for isotropic, premium-quality tool steels. * **Industry Recognitions:** Often specified as "Premium H13," "Super H13," or "ESR H13" in technical requirements. ## **3. Chemical Composition (Weight %, Typical for Premium H13)** The composition is carefully balanced and tightly controlled for optimal performance. | Element | Typical Range (%) | Role & Benefit | |---------|------------------|----------------| | **Carbon (C)** | 0.37 – 0.42 | Provides base hardness and wear resistance; optimized for toughness/hardness balance. | | **Chromium (Cr)** | 5.00 – 5.50 | **Primary alloying element.** Confers high tempering resistance ("red hardness"), oxidation resistance, and deep hardenability. | | **Molybdenum (Mo)** | 1.20 – 1.60 | Enhances hardenability, high-temperature strength, toughness, and resistance to temper embrittlement. | | **Vanadium (V)** | 0.90 – 1.10 | **Critical for wear resistance.** Forms hard, stable vanadium carbides (VC) that provide exceptional wear resistance, grain refinement, and secondary hardening. | | **Silicon (Si)** | 0.90 – 1.10 | Improves oxidation resistance and strengthens the ferrite matrix; enhances thermal fatigue resistance. | | **Manganese (Mn)** | 0.30 – 0.50 | Aids in hardenability and deoxidation. | | **Sulfur (S)** | ≤ 0.002 (Ultra-Low) | **Kept extremely low** in premium grades to maximize **toughness, polishability, and isotropic properties**. This is a key differentiator from standard grades. | | **Phosphorus (P)** | ≤ 0.015 (Low) | Minimized to prevent embrittlement. | ## **4. Typical Physical & Mechanical Properties (Heat Treated)** * **Recommended Heat Treatment:** * **Preheating:** 750-800°C (1382-1472°F) * **Austenitizing:** 1020-1050°C (1868-1922°F) * **Quenching:** Air or pressurized gas (oil quenching possible for complex shapes) * **Tempering:** Double tempering at 540-600°C (1004-1112°F) to desired hardness. * **Properties at Hardness 48-50 HRC (Typical for Die Casting):** * **Tensile Strength:** 1600 – 1800 MPa (232,000 – 261,000 psi) * **Yield Strength (0.2% Offset):** 1400 – 1550 MPa (203,000 – 225,000 psi) * **Elongation:** 8 – 12% * **Reduction of Area:** 30 – 45% * **Impact Toughness (Charpy V-Notch):** 25 – 40 J (18 – 29 ft-lb) – **Excellent for this hardness level.** * **High-Temperature Performance:** * **Hot Hardness at 600°C (1112°F):** ~45 HRC * **Thermal Fatigue Resistance:** **Exceptional** – resists heat checking initiation and propagation. * **Temper Resistance:** Maintains hardness during prolonged exposure to operating temperatures. * **Physical Properties:** * **Density:** 7.80 g/cm³ * **Modulus of Elasticity:** 210 GPa (30.5 × 10⁶ psi) * **Thermal Conductivity:** 24.0 – 26.0 W/m·K (at 20°C) * **Coefficient of Thermal Expansion:** 11.5 × 10⁻⁶/°C (20–100°C) * **Specific Heat:** 460 J/kg·K ## **5. Product Application** Premium H13 is specified for the most critical and demanding tooling applications: * **Aluminum, Magnesium, and Zinc Die Casting:** * **Cavities and Cores** for automotive (engine blocks, transmission cases), electronics, and structural components. * **Shot Sleeves, Nozzles, and Goosenecks.** * **Inserts and Cores** for high-volume production. * **Hot Forging and Extrusion:** * **Forging Dies** for brass, aluminum, and steel components. * **Extrusion Dies** for aluminum profiles. * **Punch and Die Inserts** for hot work applications. * **Plastic Injection Molding:** * **Molds for High-Temperature Engineering Plastics** (PEEK, PEI, PPS, etc.). * **Hot Runner Systems** (manifolds, nozzles). * **Molds for Abrasive or Corrosive Materials** (filled resins, flame-retardant plastics). * **Specialized Applications:** * **Glass Mold Tooling** * **Press Brake Dies** for high-temperature forming * **Tooling for Isothermal Forging** ## **6. Key Features & Advantages of Premium H13** * **Exceptional Toughness and Fatigue Resistance:** Ultra-low sulfur content and homogeneous microstructure provide superior resistance to thermal fatigue (heat checking) and mechanical shock. * **Superior Isotropic Properties:** Advanced remelting processes ensure uniform mechanical properties in all directions, critical for predictable tool performance and longevity. * **Excellent Polishability and Texture Transfer:** Extremely fine and uniform carbide distribution enables mirror-like finishes (SPI A1) and perfect replication of fine surface textures. * **Enhanced Thermal Conductivity:** Faster heat dissipation compared to many other tool steels, reducing thermal gradients and stresses in the tool. * **Outstanding High-Temperature Strength:** Maintains hardness and strength at operating temperatures up to **600°C (1112°F)**. * **Improved Machinability and Grindability:** More consistent microstructure results in better machining characteristics and reduced risk of grinding burns. * **Extended Tool Life:** Typically provides 30-100% longer service life compared to conventionally melted H13 in demanding applications. * **Reduced Risk of Premature Failure:** Superior cleanliness minimizes the risk of failure initiation at non-metallic inclusions. ## **7. Manufacturing and Processing Considerations** * **Melting Practice:** **ESR (Electro-Slag Remelting)** or **VAR (Vacuum Arc Remelting)** is mandatory for premium quality. * **Heat Treatment:** Requires precise control; vacuum heat treatment is recommended to prevent decarburization and oxidation. * **Surface Treatments:** Excellent candidate for **nitriding, PVD, or CVD coatings** to further enhance surface properties. * **Welding:** Repairable with proper procedures; preheat and post-weld tempering are essential. * **Quality Verification:** Should be accompanied by comprehensive testing reports including ultrasonic inspection, macro/microstructure analysis, and mechanical property testing. **Summary:** Premium H13 represents the pinnacle of hot work tool steel technology, offering unparalleled performance for the most demanding die and mold applications. Its superior metallurgical quality, achieved through advanced remelting processes and strict compositional control, translates directly into longer tool life, reduced downtime, and higher quality production output. For critical applications where tool failure is not an option, Premium H13 provides the reliability and performance that standard grades cannot match. -:- For detailed product information, please contact sales. -: International Mold Steel Premium H13 Hot Work Die and Mold Steel Specification Dimensions Size： Diameter 20-1000 mm Length <7028 mm Size:We can customized as required Standard： Per your request or drawing We can customized as required Properties（Theoretical） Chemical Composition -:- For detailed product information, please contact sales. -: International Mold Steel Premium H13 Hot Work Die and Mold Steel Properties -:- For detailed product information, please contact sales. -:
