Ultimate Guide to AR400 Steel Plate & Abrasion Resistant Steel Plate

In industries where equipment is constantly exposed to wear, impact and harsh operational environments, choosing the right material can dramatically improve performance and service life. Abrasion resistant steel plate — specifically the AR400 steel plate — has become a go‑to solution for engineers and fabricators seeking a balance of hardness, durability, and cost‑effectiveness. In this guide, we’ll explore what makes AR400 exceptional, its key features, applications, available forms like AR400 flat bar, and how to find reputable AR400 plate suppliers near me.

What Is Abrasion Resistant Steel Plate?

Abrasion resistant steel plates are engineered to withstand mechanical wear and tear caused by impact and sliding friction. Unlike standard structural steel, AR steel contains alloying elements and undergoes controlled heat treatment to achieve a high Brinell hardness number (BHN) and improved resistance to surface wear.

Common abrasion resistant grades include AR200, AR235, AR400, AR450, AR500, and beyond — each tailored for specific wear environments. Among these, AR400 plate offers a versatile combination of toughness and resistance suitable for many heavy‑duty applications.

What Is AR400 Steel Plate?

The term "AR" stands for Abrasion Resistant, and the number 400 refers to the approximate hardness level as measured on the Brinell scale — typically around 360–440 BHN. This places AR400 in the mid‑range hardness category, offering excellent wear resistance while maintaining good strength and formability.

According to the specifications from Emirerri Steel, AR400 is a medium‑carbon abrasion‑resistant steel plate with:

• Hardness: 360–440 BHN

• Yield strength: ~1000 MPa typical

• Width: Up to 120″

• Length: Up to 480″

• Weldability: Good with proper procedures

• Formability: Fair, requiring careful handling

These properties make it a reliable choice for most moderate to heavy wear scenarios.

Key Properties of AR400 Plate

Here’s why AR400 steel plate stands out:

1. High Wear Resistance

AR400 offers significant resistance to abrasive wear, significantly extending the service life of components compared with mild steel or standard structural steels. Its through‑hardened structure ensures that the high hardness is consistent throughout the material, not just on the surface.

2. Balanced Toughness and Durability

While its primary strength is abrasion resistance, AR400 maintains moderate impact toughness, making it suitable for parts that face both sliding and impact wear.

3. Fabrication Flexibility

Although a harder grade like AR500 may require more care during fabrication, AR400 is easier to weld, cut and machine — providing more flexibility for custom parts and assemblies.

4. Broad Size Availability

AR400 plates are stocked in large widths and lengths, accommodating many industrial sizing needs without extensive fabrication or joining.

Popular Forms: AR400 Plate & AR400 Flat Bar

While AR400 plate refers to flat sheets of wear steel, you’ll often find other shapes suited for specific jobs — notably AR400 flat bar.

• AR400 Plate: Ideal for large wear surfaces such as liners, chutes, and truck beds.

• AR400 Flat Bar: Perfect for smaller fabrications like wear strips, mounts, brackets, and custom wear components where a consistent thickness and width are needed.

Both forms are priced competitively and offer the abrasion resistance required for heavy‑wear applications.

Where AR400 Steel Plate Is Used

The versatility of AR400 steel plate means it’s utilized in many industries:

Mining & Quarrying

AR400 liners in hoppers, chutes and dump truck bodies help handle abrasive ores, rocks and minerals.

Construction & Earthmoving

Wear shoes, bucket teeth, and blade edges on bulldozers and excavators benefit greatly from AR400’s durability.

Material Handling

Conveyor liners, pulleys and crushers often employ AR400 to handle abrasive bulk materials like sand, gravel and cement.

Benefits of Abrasion Resistant Steel Plate

Investing in abrasion resistant steels like AR400 brings multiple advantages:

• Longer Equipment Life: Reduced wear‑related failures mean fewer replacements and adjustments.

• Reduced Downtime: Less frequent maintenance translates to higher uptime and productivity.

• Better ROI: Longer service life and reduced operational costs deliver better value over structural steel alternatives.

• Custom Solutions: AR steel can be cut to size using plasma, laser, waterjet or oxy‑fuel methods.

Choosing AR400 Plate Suppliers Near Me

Finding reliable suppliers ensures consistent quality and material availability. When searching for "AR400 plate suppliers near me", consider the following:

• Stock Availability: Look for suppliers with extensive AR steel inventories, including different thicknesses and sizes.

• Fabrication Services: Some suppliers offer cutting and pre‑processing to your specifications.

• Technical Support: Knowledgeable teams can help select the right grade (e.g., AR400 vs AR450) based on your application.

Companies like Emirerri Steel are known for stocking abrasion resistant steel and serving clients across industries needing wear‑resistant solutions.
