Product Introduction

Standard NM360 wear plate

Wear-resistant steel plate structure features:

Wear-resistant steel plate is composed of two parts of low carbon steel plate and alloy wear-resistant layer, the alloy wear-resistant layer is generally 1/3~1/2 of the total thickness. When working, the matrix provides comprehensive properties such as strength, toughness and plasticity to resist external forces, and the alloy wear-resisting layer provides wear-resisting properties to meet the requirements of specified working conditions.

Wear-resistant steel plate alloy between the wear-resistant layer and the substrate is a metallurgical bond. Through special equipment and automatic welding process, the high hardness self-protective alloy welding wire is uniformly welded on the substrate, and the composite layer number is one to two or even multiple layers. Due to the different shrinkage ratio of the alloy during the composite process, uniform transverse cracks appear, which is a significant feature of the wear-resistant steel plate.

The wear-resistant layer of the alloy is mainly chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are also added. The carbides in the metallographic structure are distributed like fibers, and the fiber direction is perpendicular to the surface. Carbide microhardness can reach more than HV1700-2000, surface hardness can reach HRC58-62. Alloy carbides have strong stability at high temperatures, maintain high hardness, and also have good oxidation resistance, and are completely normal for use within 500℃.

The wear layer has narrow channel (2.5-3.5mm), wide channel (8-12mm), curve (S, W), etc. It is mainly chromium alloy, and other alloy components such as manganese, molybdenum, niobium, nickel and boron are added. The carbides in the metallographic structure are distributed like fibers, and the fiber direction is perpendicular to the surface. Carbide content 40-60%, microhardness can reach more than HV1700, surface hardness can reach HRC58-62.

Wear-resistant steel plates are mainly divided into three categories: general purpose, impact resistance and high temperature resistance. The total thickness of the wear-resistant steel plate can reach a minimum of 5.5 (2.5+3) mm and the maximum thickness can reach 30 (15+15) mm; Wear-resistant steel can be rolled into the smallest diameter DN200 wear-resistant pipe, and can be processed into wear-resistant elbow, wear-resistant tee, wear-resistant reducer.

Scope of application:

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.
