What is NM500 equivalent British standard

    
    The NM500 is one of the most widely used Chinese wear-resistant steel plate for building machinery, mining machinery and other components. Its production requirements are very high, and its performance is comparable to that of its British standard, the British standard 750 (BS750).
    
    In terms of strength and toughness requirements, the yield strength of NM500 is as high as 850MPa, while the British standard 750 (BS750) is 770MPa. The impact toughness of NM500 is more than 20J/cor VWJ2, while the impact toughness of British standard 750 (BS750) is higher than 27J/cor VWJ2. The elongation rate of the two is 10%.
    
    In terms of wear resistance, NM500 and BS750 meet the requirements of NM400 and NM450 in terms of hardness, but their toughness and plasticity are higher. In terms of hardness, NM500 and BS750 meet the requirements of hardox500 and BJD600. The standards of abrasive resistance for the two is 95% and 92%, respectively.
    
    In summary, NM500 and BS750 are both excellent and wear-resistant materials for building machinery, mining machinery and other components. They have good performance and are suitable for a variety of applications. The main difference between them is that the yield strength, impact toughness and wear resistance of NM500 are higher than BS750, while the elongation rate of the two is the same, which is 10%. It can be seen that NM500 has outstanding performance compared to BS750.
