NM400 wear‑resistant steel plate
NM400 is a high-strength wear-resistant steel plate widely used in construction and mining machinery. It offers excellent abrasion resistance, with mechanical strength 3 to 5 times that of ordinary low alloy steel. The surface hardness typically ranges from 360 to 440 HBW. It is delivered in the quenched and tempered condition.
