BZS136SUP/BZS136HSUP HIGH-GRADE ANTI-CORROSION MIRROR MOULD STEEL/MOLD STEEL/PLASTIC MOLD STEEL


BZS136SUP/BZS136HSUP is a high-performance anti-corrosion mirror mould steel, specially designed to meet the demanding needs of industries requiring high-quality moulds. This steel grade is known for its superior corrosion resistance, excellent polishability, and wear resistance, making it ideal for the production of precision moulds that deliver flawless finishes and perform well under challenging conditions. Whether you are working with corrosive plastics or in humid environments, BZS136SUP/BZS136HSUP is the perfect solution for achieving long-lasting, high-quality results.


Chemical Composition

  • Carbon (C): 0.38%

  • Manganese (Mn): 0.50%

  • Silicon (Si): 0.80%

  • Chromium (Cr): 13.60%

  • Nickel (Ni): 0.25%

  • Vanadium (V): 0.22%

The carefully selected chemical components of BZS136SUP/BZS136HSUP ensure excellent corrosion resistance, high wear resistance, and superior polishability, making it ideal for a wide range of high-performance applications.


Conventional Smelting Process

BZS136SUP/BZS136HSUP is produced using advanced smelting techniques, including EF+LF+VD+VAR (Atmosphere Protection Electroslag). This production process significantly reduces non-metallic inclusions, enhancing the overall quality of the material. As a result, the steel achieves superior machinability, polishability, and uniformity, ensuring outstanding performance in demanding mould applications.


Delivery Status

  • Pre-hardened with a hardness range of HRC 35-40, or annealed (pre-hardened HRC 44-52).

This pre-hardened or annealed delivery condition provides ease of processing and immediate usability, reducing the need for additional heat treatment in most applications.


Delivery Size Options

BZ136SUP/BZS136HSUP is available in a variety of sizes to suit your specific requirements:

  • Thickness: 20-500mm

  • Width: 400-1200mm

  • Length: 2000-3000mm

  • Diameter: φ20-φ800mm

  • Length (Diameter): 2000-6000mm

These flexible size options allow for easy integration into different types of moulding projects, offering versatility and convenience for manufacturers.


Main Applications

  • Corrosive Plastic Injection Moulds: BZS136SUP/BZS136HSUP is ideal for injection moulds that work with highly corrosive materials such as PVC acetate plastics. It is also perfect for moulds used in humid environments where rust resistance is critical.

  • Optical and High-End Cosmetic Products: This steel is used in the production of optical products and high-end cosmetic products, such as camera lenses, sunglasses lenses, and medical equipment, where a flawless, high-quality finish is essential.

  • High Abrasive Injection Moulds: BZS136SUP/BZS136HSUP is also suitable for high-abrasion injection moulds, including those used for thermosetting injection materials and additives.


Key Features

  • Superior Corrosion Resistance: BZS136SUP/BZS136HSUP provides outstanding corrosion resistance, ensuring the longevity and durability of the moulds in aggressive environments.

  • High Wear Resistance: The steel offers excellent wear resistance, which is essential for high-performance moulds that need to withstand continuous use without degrading.

  • Mirror Polishing: BZS136SUP/BZS136HSUP can achieve a mirror polish finish of #12000-#14000, making it ideal for producing high-quality moulds that require smooth and precise finishes.

  • Good Machining Performance: The steel offers excellent machinability and stability after heat treatment, ensuring that it can be easily processed into complex moulds without compromising on performance.

  • Low Non-Metallic Inclusion Content: Due to the VAR production process, the steel has an extremely low non-metallic inclusion content, contributing to better polishability and reducing the likelihood of defects such as pitting and pinholes after polishing.


Conclusion

BZS136SUP/BZS136HSUP is the ultimate choice for high-grade anti-corrosion mirror mould steel, offering exceptional corrosion resistance, wear resistance, and polishability. Whether you're producing optical products, medical equipment, or corrosive plastic injection moulds, this steel ensures outstanding performance and high-quality finishes. With its ability to handle high-abrasion materials and perform well in humid and corrosive environments, BZS136SUP/BZS136HSUP is the perfect steel for industries demanding the highest standards of quality and durability.
