what is NM450 equivalent steel grade

    
    NM450 is a wear-resistant steel grade with a hardness of 450 HBW (Brinell hardness) which is mainly used for wear-resistant application requiring a high level of strength and toughness. The grade is pretty much equivalent to Hardox 450, Weldox 450, RAEX 450, and DILLIDUR 450V.
    
    NM450 steel has a wide range of applications, such as earthmoving and construction machinery, agricultural equipment, welding and steel fabrication, and industrial tools. It is ideal for manufacturing cutting tools, buckets and shovels, shear blades and blades for use in woodworking machinery. When machined, NM450 steel parts retain their shape at high temperatures and have good resistance to shock and fatigue, making them suitable for many wear and tear applications.
    
    NM450 is often compared to other wear-resistant steel grades. In comparison to its peers, NM450 has better wear and tear resistance, excellent heat treatment, high hardness, and excellent surface quality. In addition, it offers superior weldability characteristics and has higher tensile strength and yield strength than other comparable grades.
    
    In terms of its material equivalent, the most common one is Hardox 450. This is a high-hardness steel and has the same characteristics as NM450. Other equivalents include Weldox 450, RAEX 450, and DILLIDUR 450V. All of these grades offer superior wear and tear performance and material toughness.
    
    In conclusion, NM450 is a wear-resistant steel grade with a hardness of 450 HBW that can offer superior wear and tear performance and material toughness. It has excellent weldability characteristics and is often compared to other wear-resistant steel grades such as Hardox 450, Weldox 450, RAEX 450, and DILLIDUR 450V.
