Abrex 450 Plates Exporters in India

In industries where machinery and equipment are exposed to constant wear, choosing the right material is crucial to ensuring longevity, performance, and efficiency. Abrex 450 plates are a popular choice for such high-performance applications due to their exceptional hardness, durability, and wear resistance. These plates are engineered to withstand the toughest conditions, making them ideal for industries such as mining, construction, material handling, and heavy manufacturing.

In this article, we will delve into the specifications of Abrex 450 plates, including their mechanical properties, chemical composition, dimensions, and key features that make them a standout material in heavy-duty applications.

What is Abrex 450 Steel?

Abrex 450 is an abrasion-resistant (AR) steel designed to resist wear and extend the lifespan of components in environments subjected to high levels of friction and impact. With a Brinell hardness of 450 BHN, Abrex 450 is highly resistant to abrasion, making it ideal for heavy-duty applications where parts encounter rocks, sand, coal, and other abrasive materials.

Abrex 450 plates are manufactured using advanced processing techniques, ensuring consistency in quality and performance. The plates are available in various thicknesses and sizes, providing flexibility for different industrial needs.

Key Specifications of Abrex 450 Plates

Here are the most important specifications that define Abrex 450 plates:

1. Hardness

• Brinell Hardness Number (BHN): Approximately 450 BHN.
  • This high hardness ensures that Abrex 450 plates provide excellent wear resistance in environments with high levels of friction and impact.
  • The steel’s hardness is a key factor that enables its use in heavy-duty applications where parts are constantly exposed to abrasive materials.

2. Tensile Strength

• Yield Strength: Approximately 1,400 MPa (megapascals).
  • The yield strength indicates the ability of the material to resist deformation under stress, which is crucial for applications involving heavy loads and high-stress conditions.
• Ultimate Tensile Strength (UTS): Around 1,600 MPa.
  • UTS represents the maximum stress the material can withstand before breaking or failing. This high tensile strength contributes to the structural integrity of components made from Abrex 450 plates.

3. Impact Toughness

• Charpy Impact Test Value: Typically 20 J at -40°C.
  • Abrex 450 exhibits good toughness at lower temperatures, making it resistant to brittle fracture even under sudden shock loads and impact. This feature is especially beneficial in mining and construction where equipment is exposed to heavy, sudden forces.

4. Chemical Composition

The chemical composition of Abrex 450 is designed to enhance its wear resistance and overall mechanical properties. The primary elements that contribute to the performance of Abrex 450 include:

• Carbon (C): Approximately 0.30-0.40%

  • Carbon is a key element in providing hardness and strength to the steel.

• Manganese (Mn): Approximately 1.2-1.6%

  • Manganese enhances the toughness of the steel, improving its resistance to wear and deformation.

• Chromium (Cr): Approximately 0.6-1.0%

  • Chromium contributes to the steel’s resistance to abrasion and corrosion, further enhancing the wear-resistance of Abrex 450.

• Silicon (Si): Approximately 0.2-0.5%

  • Silicon improves the steel’s strength and deoxidizes during the manufacturing process.

• Phosphorus (P): Typically ≤ 0.05%

• Sulfur (S): Typically ≤ 0.05%

  • Low levels of phosphorus and sulfur ensure better weldability and prevent brittleness.

This specific combination of elements gives Abrex 450 its high hardness, excellent wear resistance, and impact toughness.

5. Thickness Range

• Thickness: Abrex 450 plates are available in a wide range of thicknesses, typically from 4 mm to 50 mm, although thicker plates can be produced upon request.
  • The varying thickness options provide versatility in applications, allowing for custom solutions depending on the required wear resistance and load-bearing capacity.

6. Width and Length

• Width: Abrex 450 plates are typically available in widths ranging from 1,500 mm to 2,500 mm.
• Length: These plates can be produced in lengths ranging from 3,000 mm to 12,000 mm (or longer depending on the manufacturer and customer specifications).
  • These dimensions allow for flexibility in design, as customers can order plates that match the size requirements of their equipment or structures.

7. Surface Condition and Finishing

• Surface Finish: Abrex 450 plates typically come with a hot-rolled finish, which gives the surface a smooth, even texture. In some cases, the plates may undergo additional treatments, such as shot blasting or pickling, to improve the surface finish for specific applications.

• Flatness and Edge Condition: The plates are typically supplied with sheared edges or milled edges, depending on customer preferences and the specific use case.
