What is the difference between NM400 and NM450
NM400 and NM450 are both high-strength steel plates used in the construction industry and are often compared to each other due to their similar properties. While they are similar in many ways, they also have some key differences that set them apart.
NM400 steel is a kind of wear-resistant steel developed byDomite Wear Technology Company, a subsidiary of South Korean steel manufacturer NSSMC. The NM400 steel plate is made of high-quality tungsten, chromium and other alloy materials, which gives the steel plate good abrasion resistance, impact resistance and fatigue strength. The main application of NM400 steel is for wear-resistant components and structures. It can be used for wear-resistant plates, liners and hoppers, crusher parts, dishes and screens, grinding media, warehousing and storage conveyors, buttons and cutting edges, as well as machinery and equipment components subjected to high-speed abrasion, friction and impact.
NM450 steel is similar to NM400 steel but with a higher yield strength. This steel is made from a combination of alloying elements such as chromium, molybdenum, copper and silicon. It is also treated with a process that increases the yield strength through heat and cold rolling, which makes the steel much stronger and tougher than NM400. NM450 steel is most commonly used in applications exposed to heavy impacts, such as wear plates and heavy construction machinery, as well as train rails and railroad tracks.
When comparing the two steels, it is important to keep in mind the differences in their usage. NM400 is best suited for applications that need wear resistance, while NM450 is better for impact-resistant applications. NM400 has a yield strength of 395-700 MPa and a tensile strength of 610-1100 MPa. Since it is a wear-resistant steel, it is also quite wear-resistant and has good flexibility and fatigue strength. On the other hand, NM450 has a yield strength of 450 MPa and a tensile strength of 600-900 MPa. Being an impact resistant steel, it is highly wear resistant, has a high impact toughness and a good strength-to-weight ratio, making it perfect for heavy-duty construction and dynamic engineering applications such as in the automotive and construction industries.
Overall, both NM400 and NM450 have much in common, but each provides unique features that can make one more suitable for a particular application than the other. While NM400 is better suited for applications that need wear resistance, NM450 is better for applications that require impact resistance. As such, it is important to choose the right steel based on the specific needs of the project.
