Which material is NM 500 equivalent

    
    NM 500 is a common type of wear-resistant steel with a nominal hardness of 500 HBW (Brinell Hardness) as measured on the Brinell hardness scale. It is an abrasion-resistant steel with an excellent combination of strength and toughness. It has an exceptionally low carbon equivalent value, is work hardenable, and has great weldability characteristics.
    
    It is commonly used in many applications and industries, such as mining, construction, agriculture, automotive, and machine components. It provides superior strength, low maintenance cost, and excellent workability with high wear resistance.
    
    The equivalent NM 500 steel is NM 750. It is a wear-resistant steel plate with a hardness of 760 HBW, which is more than double the hardness of NM 500. It has a higher impact toughness, good bendability, and excellent weldability properties.
    
    NM 750 can resist even higher levels of wear and tear. It offers an even more efficient wear protection solution for extreme abrasion and impact applications. When compared to NM 500, it is about 20% harder, boasting a nominal hardness of 758 HBW, as measured on the Brinell hardness scale.
    
    Due to its excellent hardness levels, it offers better protection against wear and abrasion, while maintaining extreme levels of formability and weldability. NM 750 is regularly used in mining, recycling contents, digging, earthmoving, and the forestry industry, among many others.
    
    NM 500 and NM 750 have the same grade features, but NM 750 has improved resistance to both sliding and impact abrasion. In addition, NM 750 is more suitable for parts that are subjected to heavy impacts, like crusher parts and conveyor components. It is also a popular choice for dump body liners, hoppers and chutes, as well as for components used in axes and arms in construction machinery.
    
    Overall, NM 500 and NM 750 are both excellent steel grades for wear-protection applications. NM 500 is a good choice for extreme wear applications while NM 750 is well suited for additional impact resistance.
