What is NM500 equivalent Indian standard

    
    NM500 is a Chinese low-alloyed high-strength steel grade crafted specially for wear-resistant applications, like mining and earth-moving machinery. The steel is characterized by increased wear resistance and toughness, enabling it to withstand heavy loads, intense abrasion, and other forces of impact.
    
    In India, NM500 has an equivalent grade, called middle-level high-strength steel (MLHS). This is an optimally balanced, safe to use, multifunctional product developed to meet the multiple demanding requirements of high-load applications. It offer higher levels of strength and extended wear resistance compared to carbon steels. Generally brought to use for heavy machines, MLHS offers excellent durability and excellent machining properties for dies, tools and other occupations.
    
    When compared to NM500, MLHS has a slightly higher carbon content and is added with elements such as Silicon, Vanadium and Manganese, that offer enhanced strength and wear-resistance. This higher content of added elements makes MLHS an excellent material choice for wear-resistant components. The steel retains hardness and toughness even at cold temperatures, making it a top choice for heavy equipment making operations.
    
    Due to its even balance of strength and extended wear resistance, MLHS is often used to manufacture parts and components for portable heavy machinery, earthmovers, excavators and drilling machinery, bulldozers, and other heavy machinery. The steel is also used in draglines, crushers, conveyors, and ripper teeth and buckets.
    
    To conclude, it can be said that the Indian equivalent of NM500 steel grade is MLHS. This grade of steel offers a unique balance between toughness and wear resistance, making it an ideal material for components that are constantly subjected to heavy workloads and force. It is primarily used in components and parts for heavy machines and earth-moving vehicles where wear is a common factor.
