AR450 Abrasion‑Resistant Steel Plate is a high‑performance quenched and tempered steel with a nominal Brinell hardness of 420–480 BHN, designed to deliver superior resistance to abrasion, impact, and wear in demanding environments. It offers a balanced combination of hardness, toughness, and formability, making it ideal for applications where sliding and abrasive wear occur frequently. Emirerristeel
Compared with lower abrasion‑resistant grades, AR450 provides higher surface hardness than AR400 while maintaining good ductility and weldability, allowing it to withstand heavy use and repeated stresses without premature failure.
