what is NM450 equivalent steel grade

.
    
    NM450 is an abrasion resistant steel plate with a hardness of 450 HBW (Brinell hardness) and is used in applications such as steel constructions, excavator armors, cone crushers, and dump truck boxes. NM450 was developed for applications requiring increased wear resistance, specifically in high wear abrasive working environments.
    
    NM450 is equivalent to many other steel grades such as ASTM A128 Grade B2, SSAB Garatec 500, NM 450 and JFE Euromax 450.
    
    NM450 is similar to SSAB's previous grade of NM 400, and it follows the principle of providing the most effective wear resistant ability combined with a good formability and an affordable cost per tonne. It provides superior resistance in fixed and mobile equipment protection against abrasive wear in corrasion, cutting and crushing environments and protects the surface of a wide range of products and structures, by providing superior wear resistance in comparison to conventional steel plates.
    
    NM450 is commonly used in applications such as hardfacing, general machinery wear protection, agricultural implement wear, wear shields, protective wear shields, chute liners and buckets, among others.
    
    NM450 steel has a good business application in a wide variety of industries. It is superior over conventional steels and alloys due to its high strength, impact resistance and wear resistance. It is typically used for mining and crusher applications, agricultural equipment, construction applications, road armor, truck beds, wear plates and hoppers.
    
    NM450 steel can be forged, heat-treated, machined and welded. Depending on the application and manufacturing process, its hardness can be adjusted by increasing or decreasing heat input during welding processes.
    
    NM450 is a cost-effective and versatile solution for wear protection and is suitable for lighter wear applications where its superior formability, impact and wear resistance combine to make it an excellent choice in numerous areas. In addition, this steel plate offers excellent weldability and more durability than other alternative plate materials.
