NM400 High Wear Resistance

NM400 High wear resistance

Construction machinery high-strength wear-resistant steel products should have high hardness, high toughness, high strength, low carbon and low alloy and other inherent characteristics to ensure the realization of the goal of "high wear resistance, easy processing, saving materials and reducing costs". Referring to Japan, Sweden and other standards, the standard has designed seven wear resistance grades NM300, NM360, NM400, NM450, NM500, NM550 and NM600. Easy for users to select materials. While ensuring high hardness, maintain good impact toughness to resist external impact loads.
