Frequently Asked Questions

Learn more about AR500 steel plate.
Abrasion-resistant steel plate is primarily selected by hardness and wear performance, not by one fixed chemical formula. Because of that, chemistry and hardening processes can vary by mill as long as the plate meets the required hardness range and performance expectations for the grade. Mill test reports or hardness reports are supplied with orders to verify the material’s properties and confirm it meets the specified AR grade.
AR400, AR450, AR500 and AR600 are abrasion-resistant steel plate grades that generally increase in hardness as the grade number rises. AR400 balances wear resistance and formability, AR450 provides more surface hardness than AR400, AR500 is used for more severe wear and impact applications, and AR600 is typically selected for the most excessive wear applications where maximum hardness is the priority. As hardness increases, formability generally decreases. Learn more about abrasion-resistant steel and how AR grades differ.
AR500 steel plate is an abrasion-resistant steel grade known for high surface hardness, toughness and resistance to wear. It is typically used in high-wear and high-impact applications where equipment or components are exposed to sliding abrasion, rubbing, heavy wear or repeated impact. AR500 has one of the highest hardness levels among common AR steel plate grades.
AR500 steel plate is less formable and less machinable than mild carbon or HSLA steel grades because of its high hardness and high-carbon alloy composition. That hardness is what gives AR500 its strong wear resistance, but it also makes the material more rigid and harder to bend, form or machine compared to lower-hardness plate grades.
AR500 steel plate is used in applications where material must withstand high levels of abrasion and impact without breaking down quickly. Common uses include truck beds, buckets, chutes, hoppers, bulldozers, excavators, underground mining equipment, truck plows and dump liners. AR500 is also used in industrial manufacturing, mining, concrete handling and construction equipment applications.
AR500 steel plate is used for extreme wear applications because its high surface hardness and toughness help it resist abrasion, impact, slide wear, rub wear and heavy wear. It can also withstand high-impact stresses at extremely low temperatures, making it a durable option for demanding applications such as mining equipment, concrete handling and heavy material handling. This durability can extend the service life of equipment and reduce how often worn parts need to be replaced.
AR500 steel plate is heat-treated through quenching and tempering to improve the hardness and toughness needed for high-wear applications. This process changes the steel’s grain structure to help increase toughness and reduce brittleness, making AR500 better suited for applications where abrasion and impact are major concerns.
