What is the NM450 vs NM400 size range?

    
    The NM450 vs NM400 size range is an important comparison for those looking to use steel in construction projects or manufacturing applications. Both grades offer excellent wear resistance, but their differences can make one more suitable than the other in various applications.
    
    NM450 is an abrasion-resistant steel plate that has a nominal hardness of 450 HBW – the highest level of scale-resistant hardness of any steel grade currently available on the market. Due to its excellent wear resistance, NM450 can be used in industries with heavy abrasive wear, such as construction and mining. This steel grade provides an economic solution to many applications where other more expensive armoring and wear-resistant steels can’t withstand the conditions they are exposed to.
    
    NM400 is also an abrasion-resistant steel plate with a nominal hardness of 400 HBW, but its wear resistance is not as high as that of NM450. Because of its comparatively lower level of wear resistance, NM400 is oftentimes used for smaller applications or for applications that are in need of a low-cost solution. Even though it has a slightly lower wear resistance than NM450, it is still considered to be highly wear-resistant and often used in applications such as dump bodies, conveyor chutes, buckets, and armor plating.
    
    When comparing the NM450 vs NM400 size range, the two grades have very similar sizes up to approximately 25mm. After this, the NM450 size range extends to approximately 40mm, while the NM400 size range only goes up to approximately 32mm. This means that the NM450 steel grade is thicker and more durable than the NM400 steel grade at sizes above 25mm.
    
    Furthermore, the NM450 vs NM400 size range also varies in terms of thickness. The NM450 steel grade is available in thicknesses between 4mm and 50mm, while the NM400 is available in thicknesses up to 40mm. Keep in mind, however, that the pre-treatment and finishing techniques used to create the steel sheets will affect the overall ideal thickness for a particular application.
    
    In conclusion, the NM450 vs NM400 size range comparison is an important consideration for anyone looking to use steel in their next construction or manufacturing project. NM450 offers a higher level of wear resistance and a larger size range than the NM400 steel grade, however it is also more expensive and may not be the ideal choice for all applications. Ultimately, when selecting a steel grade, you should consider factors such as the intended application, wear resistance, availability of sizes, and overall cost in order to determine the best steel grade for your project.
