AR 400 Wear Plate

Description

Product Description AR400 Wear Plate

AR400 wear plate is a high-carbon alloy steel designed for high hardness and abrasion resistance. Its composition, processing techniques, and mechanical properties make it an ideal choice for applications requiring resistance to wear and tear. Often used in industries like construction, mining, and material handling, AR400 wear plates are designed to withstand abrasive environments where equipment components experience high levels of friction. The “AR” stands for Abrasion Resistant, while the “400” refers to its hardness, which is around 400 BHN (Brinell Hardness Number).

This wear-resistant plate is produced by heat treating steel to a specific hardness level, making it suitable for applications that demand robust performance and durability under harsh conditions. Let’s explore the technical details and applications of AR400 wear plate in-depth.

Key Features:

• High Hardness: Offers excellent resistance to wear and impact.
• Weldability: Can be welded and formed, allowing for custom applications.
• Toughness: Retains toughness while resisting wear, making it suitable for high-impact environments.

Fabrication and Machining

• Cutting:
  • AR400 wear plate can be cut using laser cutting, plasma cutting, or oxy-fuel cutting. These methods allow for precise cuts but may require the use of high-quality tools due to the material’s hardness.
• Welding:
  • Welding AR400 wear plate is possible but should be approached with caution. Preheat and post-weld heat treatment may be necessary to prevent cracks. It’s crucial to select the correct filler metal, typically a low-hydrogen electrode, to avoid hydrogen embrittlement.
• Bending and Forming:
  • As AR400 is a hard, abrasion-resistant material, it can be difficult to bend. It’s typically used in its flat form for applications that do not require excessive bending. However, forming processes such as rolling can be performed on it with proper tooling.
• Grinding and Surface Treatment:
  • Surface grinding can be performed to improve finish quality and smoothness, though this requires specialized equipment designed to handle high-hardness materials.
