BZ2083ESR HIGH-GRADE ANTI-CORROSION MIRROR MOULD STEEL/MOLD STEEL/PLASTIC MOLD STEEL

BZ2083ESR is a high-grade anti-corrosion mirror mould steel designed for applications requiring exceptional hardness, corrosion resistance, and surface polishability. This steel grade is ideally suited for plastic moulds exposed to corrosive plastics, surgical cutting tools, fine cutlery, and other precision applications. With its chromium alloy content, it delivers outstanding polishing properties and superior corrosion resistance, making it an ideal choice for a variety of demanding industrial applications.

Chemical Composition

• Carbon (C): 0.40%

• Manganese (Mn): 0.70%

• Silicon (Si): 0.50%

• Chromium (Cr): 13.00%

• Phosphorus (P): ≤ 0.025%

• Sulfur (S): ≤ 0.003%

These chemical properties are designed to enhance both the durability and the performance of the material under extreme conditions. The high chromium content provides exceptional resistance to oxidation and wear, making it a reliable choice for mould steels exposed to aggressive environments.

Conventional Smelting Process

The manufacturing process of BZ2083ESR steel involves advanced smelting technologies, including EF+LF+VD+VAR (Atmosphere Protection Electroslag), ensuring superior material consistency and minimized impurities. This results in a steel that performs optimally in highly demanding applications, ensuring high surface quality and strength.

Delivery Status

The material can be delivered in various states to meet your needs:

• Pre-hardened (HRC 35-40)

• Annealed (HRC 44-52)

This versatile delivery range allows for flexibility in processing, ensuring that the material meets the specific hardness and durability requirements of different applications.

Delivery Size Options

BZ2083ESR is available in a range of sizes to fit various industrial requirements:

• Thickness: 20-500mm

• Width: 400-1200mm

• Length: 2000-3000mm

• Diameter: φ20-φ800mm

• Length for Large Diameters: 2000-6000mm

This variety ensures that you can find the perfect size for your mould or tool, enhancing your productivity with minimal delays.

Main Applications

1. Plastic Moulding: BZ2083ESR is often used in conjunction with corrosive plastics, offering the best corrosion resistance when hardened and low tempered with a polished surface. This makes it an ideal choice for high-performance plastic moulds that need to withstand harsh chemical environments.

2. Mirror Polishing Moulds: The steel is widely used for producing mirror-polished plastic moulds, ensuring excellent surface finish quality for industries such as cutlery, surgical tools, and razor blades.
