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.

Product Parameters

Overview:

1.Abrasion resistant steel plate grade used in high-wear applications, such as in mining equipment and concrete handling.

2.Surface hardness can range between 470-540 BHN.

3.Possesses excellent resistance to slide wear, rub wear and heavy wear.

4.Can withstand high-impact stresses, even at extremely low temperatures.

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.

Properties

The high-carbon composition and additional chemical alloys included in AR500 steel give the material enhanced hardness and wear resistance. However, the addition of high amounts of carbon also reduces the formability and strength of AR500 as compared to other steel plate grades. The hardness of AR500 also means the material is more rigid and, therefore, less machinable compared to mild carbon and HSLA steel grades.

To further enhance the properties that are desirable in high-wear applications, AR500 is heat-treated through a process known as quenching and tempering. This heat treatment process changes the grain structure of the steel material to increase toughness and reduce bitterness.
