NM400 is a kind of high-strength wear-resistant steel plate.NM400 has quite high mechanical strength, and its mechanical properties are 3 to 5 times higher than those of ordinary low alloy steel plate, which can significantly improve the wear resistance of machinery-related parts, thus prolonging the service life of the machinery and lowering the production cost. The surface hardness of the product usually reaches 360~450 HB. structural steel plate is suitable for processing and manufacturing wear-resistant wear parts of mining and various engineering machinery.
