What is NM 500 equivalent British standard

    
    NM 500 is a wear-resistant steel commonly used in the construction of various types of structures, components and machinery. It is an alloy steel composed of a mix of chromium, manganese, molybdenum, nickel, and vanadium with an addition of other elements. Its high hardness and wear resistance makes it ideal for applications that require parts that can withstand wear and environmental conditions.
    
    The British Standard 750 refers to a set of standards that cover the quality and performance of metallic materials in engineering applications. In relation to NM 500, the British Standard (BS) 75 equivalent is the Bisalloy 80. This is a quench and tempered alloy steel which is available in various sizes and is used for applications that require high strength and wear resistance. It has a slightly higher hardness compared to NM 500 and is used in industries such as mining where the working environment can be harsh.
    
    Unlike NM 500, Bisalloy 80 is a heat treated steel, transformed by quenching and tempering. It has higher toughness and ductility, meaning that it can absorb more energy in a wider range of temperatures. Furthermore, its superior structural properties as well as its superior wear resistance make it a great choice for engineering applications.
    
    All in all, NM 500 and Bisalloy 80 are both wear-resistant alloys used in engineering applications. While NM 500 can be hardened to a certain extent by cold-working, Bisalloy 80 has superior wear-resistance and toughness due to its quench and tempered process. It is thus the BS 750 equivalent to NM 500 and widely used in industries that require parts that can withstand tough and abrasive environments.
