AR500 Plate is a high-strength, abrasion-resistant steel plate with a nominal Brinell Hardness of 500 HBW. The "AR" stands for Abrasion Resistant, and the "500" denotes the hardness level.
This makes AR500 ideal for applications involving extreme wear, impact, and sliding contact, where durability and toughness are critical.
AR500 Steel Plate is a high-strength, abrasion-resistant steel with a nominal Brinell Hardness of approximately 500 HB, typically ranging from 470 to 540 BHN. It offers a tensile strength of around 200,000 psi, making it extremely durable and suitable for applications that involve heavy wear, impact, and sliding contact.
The steel's exceptional wear resistance allows it to outperform mild steel by 4–6 times, providing long-lasting performance even under the most demanding conditions.
While AR500 can be cold-formed with proper care, its weldability is limited, and pre- and post-welding precautions are recommended to maintain structural integrity.
AR500 plates are available in a variety of thicknesses ranging from 3 mm to 80 mm, with thicker options available upon request. They are offered in different forms, including sheets, rolled plates, and custom-cut shapes such as targets and liners to meet diverse industrial requirements.
Due to its extreme hardness and durability, AR500 steel plate is widely used in many industries. It is commonly employed in ballistic armor plates, providing Level III and IV protection.
Shooting ranges also benefit from AR500 for targets, including gong, silhouette, and dueling tree designs. In mining equipment, it is used for liner plates, buckets, and chutes, while heavy dump trucks utilize it for body linings and floor panels.
Additionally, AR500 steel plate finds applications in agricultural machinery, such as plows, tillers, and drag plates, and in earthmoving equipment including excavator arms, blades, and guards. It is also used in defense structures, such as armored walls, military vehicles, and bunkers, where extreme durability and wear resistance are essential.

What is AR500 material?
What is AR500 Steel? Much like AR450 and AR400, AR500 steel is a specific type of abrasion resistant steel with a surface hardness of 477-534 BHN. It is a high-carbon steel alloy that provides greater impact and sliding abrasion resistance by comparison.
What is an AR500 plate?
What Is AR500 Steel? AR500 is a hardened steel plate that offers abrasion resistance and the ability to withstand high-impact applications and excessive wear. Due to these properties, many manufacturers rely on AR500 steel for mining purposes, truck plows, armored applications, targets, and more.
What is the meaning of AR500?
AR500 Steel: A specific type of high-carbon steel known for its hardness and durability. The "AR" stands for "Abrasion Resistant," and the "500" refers to its Brinell hardness number. This makes AR500 a superior steel, especially when it
Why is AR500 steel so expensive?
AR500 steel is generally more expensive than other types of steel due to its high strength and hardness. However, its durability and resistance to abrasion make it a cost-effective choice for applications where other materials may wear out quickly.
What is the lifespan of AR500 steel?
What is the lifespan of our armor? A: Generally speaking, AR500 Armor's ballistic steel armor plates have a shelf-life of 20 years. Polyethylene plates (UHMWPE) and ceramic armor plates have a shelf-life of 5 years
How long does AR500 armor last?
Our FragLock™ coating is designed to last 20-years. The ballistic steel core of our body armor has an indefinite shelf life as long as the coating is not compromised and exposes it to moisture, to include sweat.
