Frequently Asked Questions

Learn more about AR450 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.
The “F” in AR400F and AR450F historically stood for “formable,” meaning the abrasion-resistant steel plate could be bent to a certain degree without cracking. Today, AR steel plate with or without the “F” designation is often considered interchangeable because most mills now produce formable AR plate as the standard.
AR450 steel plate is an abrasion-resistant steel grade designed for moderate-to-heavy wear applications. It offers more surface hardness than AR400 while maintaining ductility and formability, making it a common choice for bucket components, dump body trucks and construction equipment. AR450 is also referred to as AR450F when formability is emphasized.
AR450 is an abrasion-resistant steel plate grade, and the “450” generally refers to its expected Brinell hardness level. AR450 typically has a surface hardness range around the mid-400 BHN range, giving it stronger wear resistance than AR400 while still offering usable formability for many applications.
