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.

High carbon steel

Abrasion resistant steel is a high-carbon alloy steel that is produced to resist wear and stress. There are several grades of abrasion resistant steel, including AR200, AR235, AR400, AR450, AR500 and AR600.[1]

Quenching & Tempering

[

edit

]

Abrasion resistant steel undergoes a two-step heat treatment process called quenching and tempering, which alters the steel's grain structure to increase hardness and toughness.[2]

During the quenching phase, the steel is heated to an above-critical temperature and is then rapidly cooled with water. The steel is then re-heated to a below-critical temperature and air cooled, which is the tempering phase.[2]

Brinell Hardness

The hardness of abrasion resistant steel is determined by a Brinell hardness test. This test uses a small steel ball to inflict force on a material. The indentation created by the steel ball is then measured and used to calculate Brinell hardness number (BHN).[3]

Standards for Brinell hardness testing are regulated by ASTM International under E10 specifications.[5]

Applications

[

edit

]

Abrasion resistant steel is typically used in applications requiring high wear resistance, including backhoe buckets and teeth, bulldozer blades, dump truck beds, ore and coal chutes, augers and aggregate conveyors.[6] Additional uses include shooting targets and armor, AR500 steel is commonly used for these applications as higher BHN steels are more brittle.[7]
