Product Introduction

Abrasion Resistant Steel Plate NM 400

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.

Component property

The chemical composition of the wear-resistant layer of the alloy carbon content of 4 ~ 5%, chromium content of 25 ~ 30%, the volume fraction of Cr7C3 carbide in the metallographic structure of more than 50%, the macro hardness of HRC56 ~ 62, the hardness of chromium carbide HV1400 ~ 1800. Because the carbide is vertically distributed in the wear direction, the wear resistance is more than doubled compared with the cast alloy with the same composition and hardness. The wear resistance of several typical materials is compared as follows:

(1) with low carbon steel; 20 ~ 25:1

(2) with high chromium cast iron; 1.5 to 2.5:1

NM400 wear-resistant plate is a high-strength wear-resistant steel plate, which has a high wear resistance, Brinell hardness value of 400 (HBW) is mainly in the need of wear-resistant occasions or parts to provide protection, so that the equipment life is longer, reduce the maintenance and downtime brought by maintenance, and correspondingly reduce the investment of funds.

Wear-resistant steel plate has high wear resistance and good impact performance, can be cut, bend, welding, etc., can take welding, plug welding, bolt connection and other ways to connect with other structures, in the maintenance site process with time-saving, convenient and other characteristics, widely used in metallurgy, coal, cement, electricity, glass, mining, building materials, brick and other industries, compared with other materials, It has a high cost performance and has been favored by more and more industries and manufacturers.
