NM400 is a high-strength wear-resistant steel plate with considerable mechanical strength, and its mechanical properties are 3 to 5 times that of ordinary low-alloy steel plates. This type of steel plate can significantly improve the wear resistance of machine-related components, thereby increasing the service life of the machine and reducing production costs. The surface hardness of NM400 typically reaches 360 450HB. This kind of steel plate is suitable for the processing and manufacturing of wear-resistant and wearing parts for mining and various construction machinery.
NM400 is made from scrap iron by electric furnace steelmaking, and the steel quality is pure. Steel plate is a flat steel made by pouring molten steel, cooling and pressing. NM400 steel plates are divided into thin steel plates (< 8 mm, the thinnest 02 mm), medium-thick steel plate (8 60 mm) and extra-thick steel plate (60 120 mm).
The grade of NM400 is expressed as follows: "NM" represents the wear plate, and "400" represents the Brinell hardness value of the steel plate HB value. The standard implemented by NM400 steel plate is GB T24186-2009. Its delivery status can be normalized, tempered, quenched, etc., and the delivery status can also be specified according to technical requirements.
NM400 is a wear-resistant steel plate that is widely used in mechanical engineering, and its unique mechanical properties and high strength make it excellent in many fields. In addition to construction machinery and mining equipment, NM400 is also widely used in ships, bridges, construction, and other fields that require highly wear-resistant materials. When choosing NM400 steel plate, it is necessary to choose the appropriate thickness, width and length according to the specific application scenario and needs. At the same time, the delivery status is also one of the factors that need to be considered. Generally speaking, NM400 steel plate in normalized state has good comprehensive properties, so it is widely used in many situations.
In general, NM400 steel plate is a high-quality, high-strength, high-wear-resistant high-quality material, which is widely used in various fields that require wear resistance. Whether it is construction machinery, mining equipment, ships, bridges, construction and other fields, NM400 can provide excellent wear protection, improve the service life of equipment, and reduce maintenance costs.
