What is the NM500 vs nm 400 size range?

    
    The NM500 and NM400 are both part of the much broader category of wear-resistant steel plate. These plates are used in many industrial and commercial applications, primarily for the purpose of extending the life of machinery and equipment in arduous applications. These steel plates offer a high degree of abrasion and impact resistance, alongside excellent corrosion resistance.
    
    The NM500 is a 500HBW wear-resistant steel plate from Nippon Steel that offers excellent wear resistance and outstanding corrosion-resistance properties. It has a yield strength of more than 1250 MPa and a hardness of up to 550 HBW. The NM500 steel plate features abrasion resistance, high formability, and good weldability, making it a cost-effective choice for a number of applications.
    
    The NM400 is another type of hardened steel plate from Nippon Steel, which is slightly less hard than the NM500. This steel plate has a wear-resistant of up to 400 HBW, as well as a yield strength of more than 1050 MPa. The NM400 steel plate features good wear and impact resistance and excellent formability.
    
    Both the NM500 and NM400 are available in a range of thicknesses from 3 to 100mm. For most applications, thicknesses from 4 to 80mm should suffice, particularly if you’re looking for greater longevity and resistance to abrasion and impact wear.
    
    In terms of applications, both the NM500 and the NM400 are suitable for a wide range of uses. This includes mining, construction, agricultural equipment, off-road vehicles, and more. The NM500 offers increased hardness, which means it should be used in more abrasive applications, such as separating steel from ore in mining operations. The NM400, on the other hand, is more suitable for less-drastic conditions, such as agricultural machinery or off-road vehicles.
    
    When it comes to choosing between the NM500 and NM400, it’s important to consider the scope of the application. The NM500 is the higher-grade steel plate and is intended for more demanding conditions. However, it should also be kept in mind that the NM400 is more affordable, making it a good choice for less-drastic applications where cost savings is a major factor.
    
    In conclusion, the NM500 and NM400 are two different types of wear-resistant steel plates from Nippon Steel. Both feature great formability, weldability, and excellent abrasion and impact resistance. The NM500 offers the highest level of hardness and wear-resistance, making it suitable for more abrasive applications such as mining, while the NM400 offers a more cost-friendly option for milder conditions.
