NM400 wear resistant steel plate is a high-strength wear-resistant steel plate with high hardness (HB450-500) and low temperature impact toughness. Its cutting, bending, and welding properties are good. It can be used for mining machinery, construction machinery, coal mining machinery, environmental protection machinery, cement machinery, metallurgical machinery, and other industries that require a high level of wear resistance. The advantages of NM400 wear resistant steel plate are: high wear resistance, good impact resistance, good weldability, and high hardness. The disadvantages are: low toughness, poor welding performance, and low resistance to atmospheric corrosion.
- Material: NM400. The material has the advantages of high strength, high hardness, high wear resistance, etc., and can meet the requirements of various harsh working conditions.
- Thickness: usually 6-80mm, can be customized according to user needs.
- Width and length: usually the width is 1500-3500 mm, the length is 3000-12000 mm, and it can also be customized according to user requirements.
- Surface treatment: generally frosted or cut surface. High surface hardness, good wear resistance, can effectively extend the service life of the equipment.
- Chemical composition: The main components are carbon, silicon, manganese, molybdenum and other elements, which can improve the strength, hardness and wear resistance of the plate.
- Tensile strength: good tensile strength at high temperatures, greatly improving the service life.
- Application: Suitable for excavators, loaders, mining equipment, metallurgical equipment, cement equipment, power equipment and other industries, widely used in machinery manufacturing, mineral metallurgy, construction engineering and so on
