Product Description
GB NM400 HB400 AR400 Wear-resisting Steel Plate
1: NM400 Steel Introduction
NM400 steel has high mechanical strength, and its mechanical properties are three to five times higher than those of ordinary low-alloy steel plates, significantly improving the wear resistance of machinery-related parts, thus extending the service life of machinery and reducing production costs. Its surface hardness usually reaches 360 ~ 450HB, hardness values range from 360-420HB.
