What is the difference between Hardox 500 and NM500

    
    HARDOX 500 and NM500 are two different grades of abrasion-resistant steel produced by Swedish steel manufacturer SSAB. Both are made of high strength low material and are used for applications that require extreme abrasion resistance.
    
    The primary difference between HARDOX 500 and NM500 is the chemical composition. HARDOX 500 is a martensitic steel alloy containing primarily manganese and carbon. NM500 is a high-strength abrasion resistant steel containing nickel, phosphorus, and sulfur, with a hardness of 500HBW.
    
    Both HARDOX 500 and NM500 are designed to provide outstanding wear resistance in applications requiring severe wear. HARDOX 500 is the most widely used grade of abrasion resistant steel due to its combination of great strength, ductility, and low weight. The steel is commonly used in applications such as dump truck liners, chutes, industrial drums, and excavator and bulldozer bodies. NM500 on the other hand is a high-strength abrasion-resistant material suitable for structural applications with a hardness of 500 HBW. This steel is often used in applications such as blades and casings of agricultural and earthmoving equipment, concrete mixers, and construction equipment.
    
    HARDOX 500 and NM500 have several differences in terms of performance and characteristics. HARDOX 500 are the most wear and abrasion resistant among the other grades produced by SSAB. The steel is relatively low weight, has a level of mechanical properties which enable suitable fabrication, and provides good weldability. Therefore, HARDOX 500 has become a popular choice for multiple applications. NM500 on the other hand is a high-strength abrasion-resistant material with a higher impact toughness than HARDOX 500. It is also very durable and has a good weldability. However, despite being a good choice for extremely abrasive applications, the lack of ductility makes it difficult to form into shapes.
    
    In conclusion, HARDOX 500 and NM500 are both strong and durable grades of abrasion-resistant steel used in many industries. HARDOX 500 is most widely used due to its excellent strength and low weight, while NM500 provides a higher level of impact toughness and wear-resistance. Depending on the application, either HARDOX 500 or NM500 could be the best choice.
