概述
NM500 wear-resistant steel plate delivers a nominal hardness of 500 HBW through a quench and temper process. It provides 30-50% longer wear life than NM400 and is equivalent to SSAB Hardox 500 at a significantly lower cost. Suitable for mining buckets, dump truck bodies, crusher liners, chutes, and hoppers in mining, construction, cement, and material handling industries. Available in 3-120mm thickness with full-size range and custom cutting.
描述（英文）
NM500 wear-resistant steel plate is a quenched and tempered abrasion-resistant steel with a nominal Brinell hardness of 500 HBW (range 470-530). Produced to Chinese standard GB/T 24186, it delivers excellent wear performance in severe abrasive and impact environments. NM500 offers 30-50% longer service life than NM400 and is equivalent to SSAB Hardox 500 at a significantly lower cost. It is widely used in mining buckets, dump truck bodies, crusher liners, chutes, hoppers, and other high-wear applications across mining, construction, cement, and material handling industries. Available in thicknesses from 3mm to 120mm with custom cutting services.
