Research and development of high-performance and economical NM400 wear-resistant steel plate

    
    NM400 wear-resistant steel plate is a kind of high-performance and economical material that is specially used in industries requiring high wear resistance. It has a very good properties, such as high strength, good toughness, and superior wear resistance, which make it very popular in the market.
    
    NM400 is an alloy steel grade of the Japanese standard JIS G 3118. It is a specialty steel for high wear resistance and high hardness, with excellent resistance to cold, heat and abrasion. NM400 steel is often used in the manufacturing of industrial equipment, such as grinding equipment, agriculture machinery, and construction machinery.
    
    NM400 steel plate has a wide range of applications. It is used for making material parts and components, such as car fenders, roller screens, rail cars, excavator buckets, and other machinery components. It is also used in the construction of bridges and buildings, as it provides superior impact resistance and corrosion resistance. In addition, it is used in shipbuilding, as due to its good mechanical properties, it is highly capable of resisting impact, buckling, and fatigue, in tough sea and weather conditions.
    
    Generally speaking, the heat treatment of NM400 wear-resistant steel plate can be divided into annealing, quenching and tempering, normalizing and tempering, and other heat treatment processes. Through these heat treatment processes, the mechanics and technology of this material can be adjusted according to specific requirements.
    
    The toughness and plasticity of the NM400 plate will decrease with the increase of its hardness. Therefore, the NM400 plate should be kept at the lowest possible hardness and best plasticity during service.
    
    In terms of the static performance of the NM400 wear-resistant steel plate, its static strength and static fatigue strength are both excellent, which can meet the design requirements. The impact toughness of NM400 steel is also good, which is beneficial for the safety of components in long-term use.
    
    As for the corrosion resistance of NM400 wear-resistant steel plate, it has good corrosion resistance. In addition, NM400 steel has good welding performance and can be welded by carbon dioxide arc welding, manual arc welding, steel oxyacetylene gas welding, and electroslag welding.
    
    In conclusion, NM400 wear-resistant steel plate is a very economic and high-performance material. It possesses superior mechanical properties and excellent corrosion resistance. It also has good welding performance and can be used in various industries. It is thus an ideal choice for various engineering applications.
