Hot Rolled Wear Resistant Steel Plate NM400 NM500

NM 400 plates are a type of abrasion-resistant steel plate specifically designed to withstand high levels of wear and tear in harsh industrial environments. These plates are composed of a combination of iron, carbon, and other alloying elements that give them exceptional hardness and durability. One of the key features of NM 400 plates is their high Brinell hardness rating, typically ranging from 360 to 440 HBW (Brinell Hardness Number). This hardness makes them ideal for applications where abrasive materials such as rocks, minerals, and other hard substances are present, causing significant wear on equipment and machinery. The exceptional hardness of NM 400 plates is achieved through a process of quenching and tempering during manufacturing. Quenching involves rapidly cooling the steel at a high temperature, which hardens the material, while tempering involves reheating the hardened steel to a lower temperature to improve its toughness and reduce brittleness.
