Abrasion Resistant Steel Plate AR400 Steel Cutting

AR400 steel is a wear-resistant steel with exceptional hardness and durability. "400" represents Brinell hardness; AR steel typically has a Brinell hardness between 180 and 625. AR400's relatively high hardness gives it exceptional wear resistance, making it ideal for demanding applications where materials must withstand extreme wear and impact.

AR400 is a low-alloy steel plate specifically designed for high abrasion resistance. Its typical chemical composition includes carbon (C), manganese (Mn), chromium (Cr), and other alloying elements, which are precisely controlled to achieve a nominal hardness of 360-440 HBW.

AR400 exhibits excellent wear resistance, is not only tough but also has excellent machinability.

• Brinell Hardness: 360-440 HBW
• Tensile Strength: 180-200 ksi
• Yield Strength: 140 ksi
• Elongation: ~10% (typical)

Impact Toughness: Good, especially suitable for applications requiring resistance to both wear and impact.

AR400 is a wear-resistant steel with a nominal hardness of 360–440 HBW, exhibiting excellent resistance to sliding and impact wear. Despite its high hardness, it maintains good toughness, reducing the risk of cracking under heavy impacts or impact loads.

AR400 steel is used in a wide range of industries and applications, particularly those that require high durability and abrasion resistance. It is commonly used for:

 Mining and Material Handling:

• Liners for dump trucks, material transfer chutes, storage bins, buckets, and hoppers
• Chutes, buckets, and liners for abrasive material exposure

 Construction Equipment:

• Dump truck beds
• Bulldozer blades
• Loader buckets

 Manufacturing and Industrial Use: 

• Conveyor systems
• Hoppers
• Other material handling equipment

 Agriculture:

• Plow blades
• Tillage tools
• Grain handling equipment

• Original manufacturer's warranty certificate, material report, SGS/third-party testing available.

• Packaging: Waterproof packaging, standard sea freight packing.
• Supports FOB/CIF/EXW and other trade terms.

Our company offers several advanced cutting methods for precise shaping of the AR400:

• Plasma cutting – a fast and efficient processing method.
• Laser cutting – extremely high precision, especially with proper gas pressure adjustment.
• Waterjet cutting – minimizes heat exposure to the steel, thus preserving its integrity.

FAQ:

1.Is AR400 abrasion resistant?

AR400 steel is an abrasion-resistant steel known for its exceptional hardness and durability. The "400" indicates its Brinell hardness rating, which typically ranges from 180 to 625 for AR steels.

2.Is AR500 steel hard to cut?

AR500 steel can be cut using a variety of methods, including plasma cutting, waterjet cutting, and laser cutting. However, due to its high hardness and toughness, cutting the steel can be challenging and may require specialized equipment and techniques.

3.Is AR400 stronger than mild steel?

Yes, AR400 (Abrasion Resistant 400 HBW) steel is significantly stronger and harder than mild steel. While mild steel (e.g., A36) has a hardness around 130-160 BHN, AR400 boasts a hardness of 360-444 BHN, offering roughly 3 times the wear resistance and far higher yield strength. It is designed for high-impact, high-wear applications like mining and construction equipment.

4.Is AR400 stronger than AR500?

This means that AR500 is overall significantly more impact resistant than AR400, and the addition of manganese increases its sheer strength. AR500 makes up for its lack of workability with high wear resistance, allowing it to withstand intense weathering and high impact environments.

5.Is Hardox 400 the same as AR400?

You get reliable and predictable wear performance over the steel's service life. Hardox^® 400 is also covered by guarantees for thickness, flatness and bending performance .
