NM400 steel plate is a high wear resistance plate that is commonly used in mining machinery, engineering machinery, and agricultural machinery. It is made by using high-strength low-alloy structural steel as the base material and then adding a certain amount of alloying elements such as chromium, molybdenum, and nickel to improve its overall wear resistance.
The NM400 plate is characterized by its superior toughness, high wear resistance, and excellent welding performance. The surface hardness of the plate can reach 450HBW, which provides excellent protection against wear and tear caused by abrasive materials.
Due to its high wear resistance and toughness, NM400 steel plate is widely used in a variety of applications, including mining equipment, earthmoving machinery, and cement plants. Additionally, it is also a popular choice for the manufacturing of machinery parts that are frequently subjected to wear and tear.
In summary, NM400 steel plate is an excellent choice for high wear resistance applications due to its superior toughness, high hardness, and excellent welding performance.
- Specification: The thickness is generally 3mm-120mm, and the width is generally 1500mm-2500mm.
- Material: The use of hot-rolled ordinary carbon structural steel to add other alloying elements can improve the hardness and wear resistance of the steel plate.
- Features: It has good wear resistance and impact resistance, and can easily resist strong wear and impact.
- Application: Widely used in machinery manufacturing, coal mine, stone, mining, construction, metallurgy and other fields.
- Advantages: The use of advanced production technology and technology, with higher hardness and longer durability, can greatly save the replacement time and cost.
