Development of Low Carbon Medium Alloy Steel Crusher Hammer

Crusher hammer is one of the key components in the crushing process of ore grinding. It is directly mounted on the rotor shaft and its shape determines the working performance of the hammer crusher. The choice of materials for crusher hammers determines their service life and crushing efficiency. Therefore, the development of high-performance, low-carbon and medium-alloy steel is an important topic in the field of material science and engineering.
    
Background of Low Carbon Medium Alloy Steel Crusher Hammer
Low carbon steel has low carbon content and low cost, and it is suitable for most applications. It is widely used in industries such as machinery, autos and ships. With the development of industrialization and the progress of technology, low carbon steel gradually cannot meet the requirements of industry. Therefore, alloy steels have played a crucial role in industrial development. Medium alloy steel, as the name suggests, contains low alloying elements (silicon, manganese and phosphorus) in a certain proportion. This kind of steel has better properties in terms of strength, toughness and fatigue strength, due to the addition of a small amount of alloying element. Therefore, it is widely used to make crusher hammers.
    
Advantages of Low Carbon Medium Alloy Steel Crusher Hammer
Low-carbon medium-alloy steel crusher hammer has the advantages of high toughness, good wear resistance and long service life due to its low alloying element content. Compared with traditional high-carbon steel crusher hammers, low-carbon medium-alloy steel crusher hammers have higher toughness and wear resistance, which greatly improves the life of the crusher hammer and its crushing efficiency. In addition, medium alloy steel has higher fatigue strength, which can also improve its mechanical properties.
    
Drawing Description
The figure below illustrates the stress-strain curves of different materials. It can be seen that the stress-strain curve of medium alloy steel is between that of low carbon steel and high carbon steel. It has higher strength than low-carbon steel, and its toughness and wear resistance are far better than that of high-carbon steel. At the same time, its fatigue strength is higher than that of low-carbon steel, which can ensure its service life.
    
Conclusion
Low-carbon medium-alloy steel crusher hammers possess a series of advantages such as high toughness, good wear resistance and long service life. Therefore, it is widely used in crushers, where high toughness and wear resistance are required. With the development of material science and engineering, low-carbon medium-alloy steel will become a more preferred material for crusher hammers in the future.
