NM400 Plate is the mainstream medium-grade wear-resistant steel plate of the NM series, with a nominal hardness of 400HB and manufactured by quenching and tempering process. It perfectly balances high surface wear resistance and excellent core toughness, showing reliable impact resistance under moderate to heavy abrasive working conditions. The plate features good weldability, formability and machinability with simple pre-treatment, available in customizable thickness, width and length with precise dimensional tolerance and uniform material performance. As a cost-effective high-quality wear-resistant material, it’s the core choice for industrial medium-load wear-resistant structural components.
