What is NM400 steel equivalent British standard

    
    NM400 steel is a high-strength wear-resistant steel known for its superior abrasion and impact resistance. It is often used to make heavy-duty machines and parts, such as wear plates and buckets. As with any steel product, it is important to know its equivalent British standard when buying or trading NM400 steel.
    
    NM400 steel has a JIS G3125 rating which is the Japanese Industrial Standard for hot rolled steel plates – this rating is similar to that of British Standard Wear Resistant steel (BS EN), but the specifications for both standards are slightly different. NM400 steel is known for its excellent abrasion resistance, as it has a Brinell Hardness value of 400 (HB), and it is a wear resistant steel often used to make wear plates, liners, buckets, and other heavy-duty components for industrial applications.
    
    In terms of its British Standard equivalent, the closest equivalent is BS EN 10. The BS EN 10 specification is a British standard which covers the performance requirements needed for wear-resistant steels. It is a similar specification to the Japanese Industrial Standard, but with some differences. The BS EN 10 standard specifies a minimum hardness value of 360 HB, while the Japanese Industrial Standard specifies a minimum value of 400 HB. The BS EN 10 also stipulates that the steel should have a Charpy notch impact energy value of at least 50 Joules (J), whereas the Japanese Industrial Standard requires only a minimum value of 25 J.
    
    In terms of other specifications and grades, NM400 can be compared to other British standard wear-resistant steel grades such as the following: ABREX™450, ABREX™400, and ABREX™4000. These steel grades also have a similar high-strength and impact-resistant properties as NM400.
    
    In summary, NM400 steel is an extremely strong and tough wear-resistant steel, with a Japanese Industrial Standard rating of JIS G3125 and a Brinell Hardness value of 400 HB. In terms of an equivalent British Steel standard, the BS EN 10 is most similar, with some slight differences between the two. There are other steel grades with similar properties, such as ABREX™450 and ABREX™400.
