How To Choose Wear-resistant Steel Plates Of Different Materials?

Wear-resistant steel plates refer to special plate products designed for use under large-area wear conditions. There are three common types of wear-resistant steel plates: cast wear-resistant steel plates, surfacing wear-resistant steel plates and alloy wear-resistant steel plates.

Cast wear-resistant steel plate

As the name implies, it is an unrolled cast steel plate, which can be produced quickly in large quantities at a low price. However, the disadvantages are also obvious. Because there are bubbles in the molten steel during cooling, the overall strength is low. In addition, the machinability is also low.

Wear-resistant steel plate
Wear-resistant steel plate is a plate product made by welding a certain thickness of alloy wear-resistant layer with high hardness and excellent wear resistance on the surface of ordinary low-carbon steel or low-alloy steel with good toughness and plasticity. The advantage of welding is that the welding layer can be repaired in time when it is damaged, so that the welding layer can be continuously updated under the same substrate to achieve the purpose of continuous use.

Alloy wear-resistant steel plate
That is, the common high-strength wear-resistant steel plate now: NM400, NM450, NM500, factory heat-treated steel plate, its wear resistance, impact resistance and processing performance are good, widely used in mining, machinery, coal, metallurgy, electricity, cement, environmental protection and other industries.

Comprehensively compare the wear-resistant steel plates of different materials. How to choose the wear-resistant steel plate?

01 Wear resistance The surface wear resistance of the surfacing wear-resistant steel plate is high. In terms of comprehensive wear resistance, the alloy wear-resistant steel plate is higher.
02 Impact resistance Considering the adaptability of working conditions, the impact resistance of the alloy wear-resistant steel plate is better.

03 Processing performance High-strength wear-resistant steel plates can be processed into different specifications and sizes as required, and can be processed, cold-formed, welded, bent, etc. for easy use; they can be welded on site, making maintenance and replacement work time-saving and convenient, greatly improving work efficiency. Processing performance: alloy wear-resistant steel plate > surfacing wear-resistant steel plate > casting wear-resistant steel plate.
04 Cost performance Comparing the price alone, the wear-resistant steel plate is medium. Considering the product life, maintenance costs, spare parts costs and downtime losses, its performance-price ratio is much higher than other materials.
