NM400 VS NM500
NM400 and NM500 steel plates are both abrasion resistant steel plates produced by Tianjin Kilo Steel & Mechanical Co. These two steel plates are quite versatile and highly sought after due to their superior abilities in many industries. They are popular for the construction of structures such as tanks, earth moving equipment and bridges, as well as for wear parts on industrial machinery and deflecting wear on the hulls of ships and other vehicles.
The main difference between NM400 and NM500 is the hardness level of each steel. NM400 is a wear-resistant steel that’s hardness is between 360-440 HBW, while NM500 is a wear-resistant steel with a hardness of 500 HBW and is one of the hardest wear-resistant steel currently available. This makes NM500 very suitable for applications where high wear resistance is essential, such as crusher liners, grinding rolls, slag pot car and shovel wear parts.
NM400 is an abrasion-resistant steel with a nominal hardness of 400 HBW. It combines excellent weldability and good formability, enabling it to be used for a variety of wear-resistant structures. It is commonly used for the protection of structures such as crane booms and buckets, digger dipper arms, bulldozer blades and paddle blades, pickaxes, and crane outriggers. NM400 also offers very good cold forming and hot forming properties, allowing it to be formed into complex shapes while offering wear-resistant properties that extend the life of the products produced with it.
NM500 is an abrasion-resistant steel with a nominal hardness of 500 HBW, which makes it the hardest wear-resistant steel available. It almost always outperforms its NM400 counterpart when the hardness and wear resistance of the material is tested. This makes it greatly sought-after when it comes to highly demanding wear parts such as graders, guide wheels and feeder linings, rail roads, and drills, as it is able to provide long-term wear resistance with no need for frequent replacement. NM400 does also have significant applications in wear-resistant structures such as crusher parts, buckets and shovels, abrasion holes, conveyor screw sets, and wear liners. Additionally, this steel shows excellent cold and hot-forming properties, allowing it to be formed into complex shapes and sizes.
All in all, NM400 and NM500 are both excellent wear-resistant steels for different applications. Each steel has its own designated strength range, which means that one is better suited for certain applications than the other. It is important to consider the exact mechanical and physical properties of the two steel plates before selecting the right one for your project.
