Product Description
GB/T 24186 NM450 Wear-resisting Plate
1: NM450 Steel Introduction
NM450 is a high-strength wear-resistant steel plate whose designation originates from the Chinese standard GB/T 24186. “NM” stands for wear-resistant, while “450” indicates the minimum Brinell hardness value. This steel plate exhibits extremely high hardness and outstanding wear resistance, while also maintaining a certain degree of impact toughness. NM450 is typically processed through quenching or quenching followed by tempering to achieve the required mechanical properties. It is widely used in wear-resistant structural components for construction machinery, mining equipment, metallurgical machinery, and material handling equipment, such as excavator buckets, mining dump truck bodies, crusher liners, and chutes.
