NM400是高強度耐磨鋼板。NM400具有相當高的機械強度;其機械性能是普通低合金鋼板的3倍到5倍;可顯著提高機械相關部件的磨損耐性;因此提高機械的使用壽命;降低生產成本.該產品表面硬度通常達到360~450HB。用于礦山及各種工程機械用耐磨易損件加工和制造等適用的結構鋼板。NM400是耐磨鋼板的一種。NM-表示耐磨用途的"耐"和"磨"字漢語拼音首位字母 400是布氏硬度值HB值。(400硬度值是廣義的，國產NM400硬度值范圍360-420。)
NM400耐磨鋼板廣泛應用于工程機械、礦山機械、煤礦機械、環保機械、冶金機械等產品零部件。挖掘機、裝載機、推土機鏟斗板、刃板、側刃板、刀片。破碎機襯板、葉片。
