BZ2344ESR HOT WORK MOULD STEEL/MOLD STEEL/ALLOY STEEL/DIE CASTING MOLD STEEL


BZ2344ESR is a high-performance hot work mould steel, specifically designed for use in die casting molds, aluminum extrusion molds, and industrial applications requiring exceptional thermal fatigue resistance, wear resistance, and high-temperature stability. Manufactured using advanced electroslag remelting (ESR) technology, this alloy steel ensures high durability and performance in extreme conditions. BZ2344ESR is ideal for automobile, motorcycle engine shells, and aluminum alloy extrusion applications, ensuring superior performance and extended mold life.


Conventional Smelting Process

BZ2344ESR is produced using the advanced EF+LF+VD+ESR smelting process, which enhances the steel's microstructure, minimizes non-metallic inclusions, and improves overall material properties. The electroslag remelting (ESR) process results in cleaner, more uniform steel, offering superior machinability and polishability for precision manufacturing.


Delivery Status

  • Spheroidizing Annealing: Hardness ≤HB235

This delivery status ensures that BZ2344ESR is pre-annealed and ready for further processing, making it easy for manufacturers to use the material in various applications with minimal additional treatment.


Delivery Size Options

BZ2344ESR is available in a variety of sizes to meet different moulding requirements:

  • Thickness: 20-500mm

  • Width: 400-1200mm

  • Length: 2000-3000mm

  • Diameter: φ20-φ800mm

  • Length (Diameter): 2000-6000mm

These size options provide flexibility, allowing manufacturers to select the right dimensions for their specific needs, whether for die casting or extrusion applications.


Main Applications

  • Aluminum Extrusion Molds: BZ2344ESR is particularly suitable for creating aluminum extrusion molds, ensuring high-quality production of industrial aluminum components and aluminum alloy extrusions.

  • Die-Casting Molds for Automotive and Motorcycle: This steel is ideal for manufacturing die-casting molds used in automotive applications, such as motorcycle engine shells and various car lamp reflector shells, offering superior mold durability and longevity.

  • Complex-Shaped Aluminum Alloy Extrusion Molds: BZ2344ESR excels in the production of complex-shaped molds for aluminum alloys, including sunflower series products, ensuring high-quality outputs in difficult-to-cast geometries.

  • Mold Longevity: The mold life for BZ2344ESR is highly reliable, with typical lifespans ranging from 30,000 to 80,000 cycles, and it can produce up to 5-10 tons of aluminum in extrusion molding applications.

  • Enhanced Performance Over H13/1.2344: BZ2344ESR offers improved performance over conventional H13 and 1.2344 steels, addressing common issues such as early erosion and cracking.


Key Features

  • High Thermal Fatigue Resistance: BZ2344ESR provides exceptional thermal fatigue resistance, which enhances mold life and performance in high-temperature applications such as die casting and aluminum extrusion.

  • Superior Wear Resistance: The steel offers excellent wear resistance, making it suitable for high-abrasion environments, ensuring longer operational life and reducing the frequency of mold replacements.

  • Exceptional High-Temperature Stability: BZ2344ESR can withstand high working temperatures without compromising its structural integrity, making it ideal for high-speed die casting and aluminum alloy die casting.

  • Enhanced Durability in Harsh Conditions: The steel's unique composition provides superior resistance to thermal cracking, water cracking, and R-shaped corner cracking, making it perfect for demanding applications in high-pressure die casting.


Conclusion

BZ2344ESR Hot Work Mould Steel is an advanced material engineered for high-performance die casting molds, aluminum extrusion molds, and complex industrial applications. With its high thermal fatigue resistance, wear resistance, and thermal cracking resistance, it offers significant advantages over traditional mold steels, ensuring longer mold life and greater productivity. Whether used for automotive die casting or aluminum extrusion, BZ2344ESR delivers reliable and consistent results, making it the ideal choice for manufacturers looking to improve efficiency and mold longevity.
