What Is H13 ESR Steel and DIN 1.2344 ESR Steel?

• H13 ESR Steel is an electroslag remelted variant of the widely used AISI H13 hot-work tool steel. ESR processing refines cleanliness, reduces inclusions, and improves isotropy, making it ideal for demanding hot-work applications with stringent requirements for toughness, thermal fatigue resistance, polishability, and die life.

• DIN 1.2344 ESR Steel is the European designation corresponding to H13 ESR. The ESR route enhances performance over conventional H13/DIN 1.2344 by delivering superior micro-cleanliness and consistency—critical for high-cycle die casting, extrusion tooling, plastic molds requiring premium finishes, and complex tool geometries.

Why Choose ESR (Electroslag Remelted) for H13/DIN 1.2344?

• Superior cleanliness and homogeneity: Lower non-metallic inclusions and improved segregation control.

• Enhanced toughness and fatigue resistance: Better resistance to heat checking, thermal fatigue, and cracking.

• Excellent polishability and surface quality: Suitable for mirror finishes in plastic mold cavities and demanding die faces.

• Improved isotropy: More uniform properties through section thickness—vital for large dies and molds.

• Better die life: Longer service life in aluminum die casting, hot forging, and extrusion conditions.

Key Focus: H13 ESR Steel and DIN 1.2344 ESR Steel as Workhorses for Hot-Work Applications

• Aluminum pressure die casting dies and cores

• Shot sleeves, sprue bushings, and thermal control inserts

• Hot-work extrusion dies, mandrels, and tooling for aluminum and magnesium

• Die-casting tooling requiring high thermal fatigue resistance

• Plastic mold components demanding high corrosion resistance with excellent polishability (especially when combined with suitable coatings and surface treatments)

• Forging dies, punches, and tools exposed to repeated thermal cycles and impact

Typical Chemical Composition for H13/DIN 1.2344 (Indicative)

• Carbon (C): ~0.32–0.45

• Chromium (Cr): ~4.8–5.5

• Molybdenum (Mo): ~1.1–1.5

• Vanadium (V): ~0.8–1.2

• Silicon (Si): ~0.8–1.2

• Manganese (Mn): ~0.2–0.5
  Note: ESR variants share the same nominal composition but offer improved cleanliness and property consistency due to remelting. We provide heat-specific certificates with actual results.

Mechanical and Thermal Properties (Typical, Heat-Treat Dependent)

• High hot hardness retention: Maintains strength at elevated temperatures common in die casting cycles.

• Excellent toughness: Resists chipping and cracking in demanding die features and sharp radii.

• Thermal fatigue resistance: Minimizes heat checking and surface network cracking under repeated thermal cycling.

• Wear resistance: Suitable for high-friction zones, especially when paired with nitriding or PVD/CVD coatings.

• Dimensional stability: ESR route reduces the risk of distortion, aiding precision fits in multi-cavity dies.

Processing Recommendations for H13 ESR Steel and DIN 1.2344 ESR Steel

• Preheating: Preheat slowly and uniformly (e.g., in stages up to 600–700°C) to minimize thermal shock before hardening.

• Austenitizing: Typical hardening temperatures around 1000–1050°C, depending on section size and property targets.

• Quenching: Gas or oil quench, pressurized gas in vacuum furnaces for precise control and reduced distortion.

• Tempering: Multiple tempering cycles are recommended to achieve the desired working hardness (common ranges 44–52 HRC for hot-work dies; consult our team for your application). Avoid low-temperature tempering ranges prone to secondary hardness plateaus or embrittlement.

• Nitriding: Recommended for enhanced surface hardness and wear resistance without excessive dimensional change. Common for shot sleeve bores, gate areas, and sliding components.

• Surface treatments: PVD/CVD coatings or nitriding/oxidizing cycles can improve galling resistance, release, and thermal fatigue performance.

Where H13 ESR Steel and DIN 1.2344 ESR Steel Excel

• Aluminum die casting: Gates, runners, inserts, cores, dies, shot sleeves, and plunger tips.

• Pressure die casting: High thermal cycling environments where cracking and heat checking are critical.

• Extrusion tools: Dies, mandrels, and tooling for aluminum profiles needing hot strength and stability.

• Plastic molds: Components requiring polishability and robust wear behavior; ESR cleanliness aids surface finish.

• Forging tools: Impression dies, punches, and hammers exposed to impact and temperature fluctuations.

• Hot shear blades and hot-cut tooling: Benefit from hot hardness and toughness balance.

• Core pins and sleeves: Nitrided or coated H13 ESR performs well where release and wear are concerns.

Comparing H13 ESR Steel vs Conventional H13

• Cleanliness: ESR is cleaner, reducing inclusion-related initiation points for thermal fatigue cracking.

• Polishability: ESR supports higher gloss finishes and fewer polishing defects in mold cavities.

• Isotropy and consistency: More uniform properties across section thickness—advantageous for large dies.

• Die life: Typically longer in high-stress, high-temperature service.

• Cost-to-performance: ESR may come at a premium, but the lifecycle cost often improves due to reduced maintenance and downtime.
