What is AR400 Steel plate?

AR400 steel plate is a type of abrasion-resistant steel known for its hardness and toughness. The "AR" in AR400 stands for "abrasion-resistant," and the 400 indicates the Brinell hardness number, which is a measure of hardness. AR400 steel is designed to withstand wear and abrasion, making it suitable for applications where the material comes into contact with abrasive materials or surfaces.

Key properties include:

Hardness : AR400 steel typically has a hardness of around 400 Brinell, which makes it durable and resistant to abrasion.

Toughness : Despite its hardness, AR400 steel also possesses good toughness, allowing it to withstand impact and deformation without fracturing

Weldability : AR400 steel can be welded, although special precautions are usually taken to avoid issues like cracking. Preheating and post-weld heat treatment may be necessary depending on the welding method used.

Formability : While it is harder than many other types of steel, AR400 can still be formed and machined, though it may require more force and specialized equipment..

AR400 Steel plate Partner

commonly used in applications such as:

Mining equipment : Buckets, liners, and screens in mining equipment are often made from AR400 steel to withstand the abrasive nature of mined materials.

Construction equipment : Components like bulldozer blades, excavator buckets, and wear plate on construction machinery benefit from the abrasion resistance of AR400 steel.

Material handling : AR400 is used in conveyor systems, chutes, and hoppers where materials with abrasive characteristics are transported.

Aggregate processing : Equipment involved in crushing and processing aggregate materials may use AR400 steel to resist wear.

It's important to note that while AR400 steel is excellent for applications involving abrasion, it may not be the best choice for every situation. Factors such as impact resistance, corrosion resistance, and cost should also be considered when selecting materials for specific applications.

Steel Plate Sizes

Steel Warehouse can supply the following sizes of AR400 Steel:

  • .25”-0.315” thickness offered in 48”- 65” wide, cut to your requested length
  • .375”-2.00” thickness offered in standard sizes (96” x 240”/288”)

Properties

AR400 steel is one of the more abrasion resistant steels available. As you increase hardness, however, you are creating a more rigid steel. This means that AR400 is less weldable and formable than other types of AR steel.

AR400 has the following chemical and mechanical properties:

  • Welding = Decent
  • Machining = Good
  • Abrasion Resistance = Excellent
  • Corrosion Resistance = Good
  • Forming = Fair

Steel Requirements

AR400 meets ASTM E10 standards for mechanical properties. The flatness and thickness standards are also 50% of that specified in ASTM A-6 with special tolerances available..

Benefits of AR400

The main benefit of AR400 steel plate, like any abrasion resistant steel, is its ability to resist wear and abrasion. Because of this, it can lead to less down time and can improve the longevity of your equipment by reducing erosion and wear. All of this, in turn, can lead to maximized production time.
