NM400 is a high strength wear-resistant steel plate. NM400 has quite high mechanical strength; Its mechanical properties are 3 to 5 times that of ordinary low-alloy steel plates; It can significantly improve the wear resistance of mechanical parts. Therefore, improve the service life of the machine; Reduce production costs. The surface hardness of the product usually reaches 360 ~ 450HB. Used in mining and various construction machinery for wear-resistant parts processing and manufacturing and other suitable structural steel plate.
