NM400 steel vs NM450 steel

    
    NM400 steel and NM450 steel are wear-resistant rubber sheets used in a variety of industrial applications. Both are produced with similar processing techniques and have comparable wear resistance ratings. However, their unique qualities set them apart from one another in terms of the specific application for which they are best suited.
    
    NM400 steel is known for its superior wear resistance, toughness, and excellent weldability. It is one of the best steel plates used for applications where wear needs to be monitored or to provide cushioning against abrasion. It is especially well-suited to applications involving extremely high wear resistance or wear systems where long wear life is preferred. In addition, NM400 steel offers higher corrosion resistance than that of other wear-resistant steels, giving it an advantage over other materials in terms of corrosion protection.
    
    NM450 steel is an upgraded version of the NM400 steel. It is known for its superior corrosion resistance and wear resistance in comparison to the NM400 steel. This makes it ideal for applications involving extremely tough environments or ones where corrosion protection is paramount. The increased wear resistance characteristics of the NM450 steel make it particularly useful for applications involving heavily loaded parts or those where corrosive materials must be sealed off from the environment.
    
    In terms of comparison, the NM400 steel grade outperforms the NM450 steel in terms of wear resistance, with the NM400 steel being rated higher than the NM450 steel. However, the NM450 steel grade offers superior corrosion resistance in comparison to the NM400 steel.
    
    Although both NM400 steel and NM450 steel are wear-resistant rubber sheets, their unique properties and characteristics set them apart in terms of the applications for which they are best suited. The NM400 steel offers superior wear resistance than the NM450 steel, making it better suited to applications where wear needs to be monitored or to provide cushioning against friction. In contrast, the NM450 steel has superior corrosion resistance and wear resistance than the NM400 steel, making it appropriate for applications involving extremely tough environments or ones where corrosion protection is paramount. As a result, the choice between these two wear-resistant rubber sheets depends on the application and should be decided accordingly.
