概述
NM400 wear-resistant steel plate delivers a nominal hardness of 400 HBW through a quench and temper process. As the baseline grade of the NM series, it offers the best combination of wear resistance, formability, weldability, and impact toughness. Equivalent to SSAB Hardox 400 at a significantly lower cost. Ideal for excavator buckets, dump truck bodies, bulldozer blades, crusher liners, chutes, and hoppers in mining, construction, cement, and material handling industries. Available in 3-120mm thickness with custom cutting.
描述（英文）
NM400 wear-resistant steel plate is a quenched and tempered abrasion-resistant steel with a nominal Brinell hardness of 400 HBW (range 360-420). Produced to Chinese standard GB/T 24186, it is the most widely used wear-resistant steel grade, offering excellent abrasion resistance combined with superior formability, weldability, and impact toughness. NM400 is equivalent to SSAB Hardox 400 at a significantly lower cost. It is the ideal choice for moderate to high wear applications requiring fabrication, including excavator buckets, dump truck bodies, bulldozer blades, crusher liners, chutes, and hoppers across mining, construction, cement, and material handling industries. Available in thicknesses from 3mm to 120mm with custom cutting services.
