What are the advantages of Push Mower Blade made of 40 manganese steel for grass species of different hardness and density?

The 40 manganese steel of Push Mower Blade has a high hardness, usually between 40 and 45 HRC, which allows the blade to effectively resist friction and wear of grass blades during the cutting process and maintain long-term sharpness. High hardness means the blade is better able to penetrate and cut harder grass species, such as certain grass weeds or perennial grasses. The wear resistance of manganese steel is better than that of ordinary carbon steel. Therefore, during long-term use, the 40 manganese steel blade can maintain a good cutting effect even when facing high-density grass or grass roots in hard soil, reducing wear and tear. resulting in performance degradation.
The presence of manganese in steel can effectively form hard phases, such as carbides, etc. These hard phases are evenly distributed in the steel matrix, significantly increasing the hardness of the blade. The high hardness means that the blade can easily penetrate various grass types during the cutting process, whether it is delicate lawn grass or tough weeds, it can achieve clean cuts. At the same time, the enhanced wear resistance allows the blade to maintain good cutting efficiency even under long-term, high-intensity mowing operations, reducing the need for frequent blade replacement due to wear.
Toughness is the ability of a material to resist breaking or deforming when impacted or bent. The addition of manganese steel not only increases the hardness of the blade, but more importantly, enhances its toughness. This toughness allows the blade to better absorb and disperse impact energy when encountering complex and changeable mowing environments, such as stones, roots or other hard objects hidden in the grass, thereby avoiding breakage or serious deformation. . This toughness also helps maintain the stability and balance of the blade during high-speed rotation of the lawn, ensuring consistent and safe cutting results.
With its high hardness, wear resistance and good toughness, the 40 manganese steel blade shows wide adaptability to a variety of grass species with different hardness and density. From soft lawn grass to rough weeds, to hard grass roots buried deep in the soil, it can be easily handled. Wet grass after rain, lawn covered with morning dew, or even low-lying areas with long-term water accumulation will not have a significant impact on the 40 manganese steel blade, ensuring that it always maintains excellent cutting performance and working condition.
Because the 40 manganese steel blade has many of the above advantages, its service life is significantly improved compared to ordinary blades. Users can reduce the frequency of blade replacement, thereby reducing maintenance costs and time costs. At the same time, good wear resistance and corrosion resistance also help reduce downtime caused by blade damage and improve the overall efficiency and continuity of mowing operations.
The push lawn mower blade made of 40 manganese steel performs well in lawn mowing operations due to its high hardness, wear resistance, good toughness and impact resistance, and adaptability to a variety of grass species. It can effectively cut grass species of different hardness and density and maintain sharpness and stability for a long time.
