Alloy & Abrasion Resistant Steel Plate


AR400 steel plate is a type of abrasion-resistant quenched and tempered steel plate that is specifically designed to provide impact toughness as well as a high-level resistance to abrasion. The “AR” in AR400 stands for “Abrasion Resistant,” indicating its primary characteristic. The 400 refers to a Brinell hardness range between 360 to 444 BHN.  This hardness is manufactured using elements such as manganese, chromium, or nickel to enhance its toughness properties. AR steel plate is commonly used in applications where the material is exposed to abrasive conditions, such as mining equipment, construction machinery, material handling systems, or any application where impact or wear is expected.
