The NM500 vs nm400 material
NM500 and NM400 are both abrasion resistant steel materials that offer a number of different benefits for different applications. The two steels are often compared in order to understand their strengths and weaknesses, specifically NM400 vs NM500, as well as how they can be employed in different applications.
NM400 is a high strength wear-resistant steel plate with a hardness of 400 HBW. It is mainly used in high-wear conditions and is a key component in the broad range of wear-resistant steel products offered by customer. It has good welding performance, fatigue strength and a good cutting performance. NM400 has an average hardness of 400HBW, and its minimum yield strength is 200MPa. As an abrasion resistant steel, it is well suited for applications such as excavator buckets and blades, bulldozer blades, loader blades and other mining and earth moving equipment.
NM500 is a wear-resistant steel plate with a hardness of 500 HBW, which is superior to NM400. It is mainly used in engineering mechanical components such as coal crusher hammers, shovels, stacking conveyors, and other wear parts with high wear resistance requirements. NM500 has an average hardness of 500HBW, and its minimum yield strength is 700MPa. In addition to its superior wear resistance, it also has good impact toughness and fatigue strength, and its mechanical properties are very similar to those of high tensile strength structural steels. NM500 steel is widely used in mining, cement and power plants, as well as other mining and construction machinery.
When it comes to the comparison between NM400 and NM500, the NM400 has a higher yield strength than the NM500 and a higher hardness. The lower hardness of NM400 makes it more susceptible to impacts and abrasions but also more ductile when welding. The higher hardness of NM500 means it has greater strength and wear resistance, making it more suited to applications that require higher strength. However, when comparing the two steels in terms of overall wear resistance, NM500 is much more wear resistant than NM400.
On the whole, NM400 is more suited for applications requiring strength and ductility, while NM500 is preferred for applications that require higher wear resistance. These two steels can easily be combined and used together for the best performance in a particular application. Each steel has its own particular properties, so it pays to consider them both before making a decision. No matter which alloy steel is chosen, the correct specification and composition will ensure the best performance and service life for any particular application.
