    Introduction to NM500 Wear Resistant Steel
    
    NM500 wear-resistant steel is a kind of high-strength and wear-resistant steel plate with a typical hardness of 500HB and an average wear-resistant layer of 13.5mm. It is widely used in mining and construction machinery, and plays an important role in these industries, due to its superior wear resistance. The wear resistant layer of NM500 steel plate can effectively prevent corrosion and oxidation of steel, reduce the damage of wear parts, and extend the service life of construction machinery.
    
    NM500 Wear Resistant Steel Wear-resistant Performance
    
    The excellent wear-resistant properties of NM500 wear-resistant steel make it a good choice for the production of construction machinery parts. Its wear-resistant performance mainly includes excellent wear resistance, good impact toughness, uniform surface hardness, and good weldability.
    
    Firstly, NM500 wear-resistant steel has excellent wear resistance. The abrasion resistance of NM500 wear-resistant steel can meet the requirements of the application environment, which helps to extend the service life of construction machinery parts. In addition, its wear-resistant effect can be improved after the surface coating or heat treatment.
    
    Secondly, NM500 wear-resistant steel has good impact toughness. Under the action of external force, it can absorb and dissipate energy, and it will not cause large deformation and fracture.
    
    Thirdly, NM500 wear-resistant steel has uniform surface hardness. It can maintain the average surface hardness for a long time, and the surface hardness will not easily change due to wear.
    
    Finally, NM500 wear-resistant steel has good weldability. It can be welded with carbon steel, low alloy steel and stainless steel, and the welding performance is good.
