Hardox 400 vs NM400

To tell the difference between the two grades the Hardox400 and the NM400 we must first discuss their individual capabilities and optimal uses.
    
    The Hardox400 grade is an abrasion-resistant steel produced by SSAB, a leading Swedish steel manufacturer, for heavy wear environments. This grade makes use of an extra-shoot-hardening process to ensure that it offers improved shock resistance, better surface stability and durability, and higher than normal wear resistance. Hardox400 is ideal for mining and excavating applications, as well as general machine parts, construction and agricultural equipment, and even the military and heavy trucking industries. It is also commonly used in any situation where maximum abrasion resistance is a must.
    
    The NM400 grade, also produced by SSAB, is designed for use in extreme wear and impact environments. Featuring similar reinforcing elements as Hardox400, NM400 also offers impressive toughness, as well as improved formability and welding in comparison to other abrasion-resistant steel grades. This grade is optimal for any type of high-impact environment where protection against wear and destruction is critical, including industries such as mining and quarry, heavy trucking, construction, forestry, metalworking and automotive.
    
    As with any engineering decision, it is important to take the unique needs of a project into consideration when deciding which abrasion-resistant steel grade to use. Where maximum wear resistance is not a priority, Hardox400 may be the more cost-effective option for a project. NM400, on the other hand, is typically the better choice for maximum abrasion and impact resistance. When faced with a project requiring the highest levels of wear and impact protection, NM400 gives the user trusting assurance that their investment will remain secure against significantly higher levels of wear and destruction. It is also important to ensure that the correct thickness and plate size is selected for each project, as the steel must be thick enough to ensure adequate protection.
