2024 Wear Resistant Steel Plate
2024 Wear Resistant Steel Plate
The traditional wear-resistant steel used for construction machinery is generally high manganese steel, although high manganese steel has work hardening, but in the process of its use after the impact stress has a strong hardening ability, so it can only play its role under a large impact load, and for the impact load is not large working conditions, the hardness of the wear resistance can not be improved, and high manganese steel after work hardening, its yield strength is not High, under the more vigorous action, the workpiece will sometimes crack, it is difficult to achieve the expected service life. Therefore, compared with high manganese steel, in recent years, low alloy wear-resistant steel used to make small and medium-sized mechanical materials is also applied in the field of construction machinery, extending and expanding the use of high manganese steel, has been recognized by the machinery industry, and has become a trend.
