AR500 steel is an abrasion-resistant steel known for its hardness and toughness. It is designed to withstand wear, impact, and abrasion from hard surfaces. AR500 steel is commonly used in applications where there is a need for resistance to abrasive wear, such as armor plating, targets for shooting ranges, mining equipment, and heavy machinery components subjected to harsh environments.

AR500 steel chemical composition

The chemical composition of AR500 steel can vary slightly depending on the manufacturer, but typically it consists of the following elements in approximate percentages:

Carbon (C): 0.31% - 0.38%

Manganese (Mn): 0.70% - 1.20%

Phosphorus (P): 0.025% (max)

Sulfur (S): 0.010% (max)

Silicon (Si): 0.20% - 0.35%

Chromium (Cr): 0.80% - 1.10%

These elements contribute to the hardness, toughness, and abrasion resistance of AR500 steel, making it suitable for applications where resistance to wear and impact is crucial.

AR500 steel mechanical properties

The mechanical properties of AR500 steel typically include:

Hardness: AR500 steel is known for its high hardness, typically ranging from 470 to 540 Brinell hardness number (HBW).

Tensile Strength: The tensile strength of AR500 steel is generally around MPa (181 ksi) or higher.

Yield Strength: AR500 steel typically has a yield strength of around MPa (160 ksi) or higher.

Elongation: The elongation at break for AR500 steel is generally low, typically around 10% or less.

Impact Resistance: AR500 steel offers good impact resistance due to its hardness and toughness, making it suitable for applications where impact and abrasion are common.

These mechanical properties make AR500 steel well-suited for use in applications that require high strength, hardness, and resistance to wear and impact.

AR500 steel is commonly used in various applications that require resistance to abrasive wear and impact. Some typical applications of AR500 steel include:

Armor Plating: Used for body armor, vehicle armor, and protective structures due to its high hardness and toughness properties.

Shooting Targets: AR500 steel plates are used as shooting targets in ranges due to their ability to withstand impacts from bullets without deforming significantly.

Mining Equipment: Components such as buckets, liners, and screens in mining equipment benefit from the abrasion resistance of AR500 steel.

Heavy Machinery: Wear-resistant parts in heavy machinery, construction equipment, and agricultural machinery benefit from the durability of AR500 steel.

Material Handling: Chutes, conveyor components, and wear liners in material handling systems use AR500 steel to resist abrasion from bulk materials.

Industrial Applications: Various industrial applications like hoppers, crushers, shredders, and recycling equipment make use of AR500 steel for its wear-resistant properties.

These applications leverage the hardness and toughness of AR500 steel to enhance durability and extend the life of components subjected to abrasive wear and impact.

What is the AR500 steel plate equivalent to?

AR500 steel plate is an abrasion-resistant steel with a Brinell hardness range of 470-540, designed to withstand wear and impact from hard surfaces. In terms of equivalent materials, it is similar to other abrasion-resistant steels like Hardox 450 and Hardox 500, which offer comparable hardness and toughness characteristics for applications requiring resistance to abrasive wear.

Is AR500 steel bulletproof?

AR500 steel is not considered bulletproof, but it is known for its high hardness and abrasion resistance properties. While AR500 steel can withstand impacts from bullets to some extent due to its hardness, it may not provide complete protection against all types of ammunition or high-velocity rounds.

For ballistic applications requiring bulletproof protection, specialized materials like ceramic plates, aramid fibers (Kevlar), ultra-high molecular weight polyethylene (UHMWPE), and composite armors are typically used to provide the needed level of ballistic resistance. These materials are designed specifically to dissipate and deform the energy of a projectile, offering better ballistic protection compared to AR500 steel alone.

AR500 Steel Plate

AR500 abrasion resistant steel plate offers high surface hardness for excessive wear and high-impact applications. 

What is AR500 Steel?

AR500 is a grade of abrasion resistant (AR) steel plate that is known for its hardness, toughness, and resistance to wear and tear. This grade has one of the highest levels of hardness out of the common AR steel plate grades - with a Brinell Hardness Number (BHN) of between 460-544 - and is typically used in high-wear and impact applications. AR500 steel plate meets ASTM E10 specifications for Brinell hardness testing.

Overview:

• Abrasion resistant steel plate grade used in high-wear applications, such as in mining equipment and concrete handling.
• Surface hardness can range between 470-540 BHN.
• Possesses excellent resistance to slide wear, rub wear and heavy wear.
• Can withstand high-impact stresses, even at extremely low temperatures.
• Composition and hardening processes differ between mills. Mill test reports are supplied with each order.

Benefits of AR500 Steel

The hardness and toughness of AR500 steel plate make it extremely resistant to wear and impact. These properties make AR500 steel a durable, long-lasting material, which is crucial in applications that require materials that can withstand extreme wear.

The durability of AR500 also means that the material needs to be replaced less often than materials that have lower resistance to abrasion, which can lower material costs and prevent devastating equipment failures.
