Steel shot has good toughness, impact resistance, long service life, good rebound elasticity, and strong adhesion

Description :

　　During the shot blasting process, the steel shot and steel sand of the shot blasting machine need to continuously impact the workpiece to remove oxide scale, casting sand, rust, etc. At the same time as the steel shot and steel sand themselves impact the workpiece, they also need to have strong impact resistance. That is to say, steel shot and steel sand materials need to have strong resistance to impact loads (the ability of steel shot and steel sand to resist impact loads without damage is called steel shot and steel sand impact toughness).

　　The impact performance of steel shot and steel sand is good. As some steel shot and steel sand manufacturers claim, high hardness of steel shot and steel sand does not necessarily mean durability. It is simply good steel shot and steel sand. In fact, this viewpoint is very paranoid because as long as the hardness of the steel shot and steel sand increases, the toughness of the steel shot and steel sand decreases accordingly. Moreover, as the hardness of the steel shot and steel sand increases, it is easy to break during the shot blasting process, which is not suitable for some workpieces with high hardness steel shot and steel sand, but suitable for those with good toughness.

　　To obtain ideal steel shot and steel sand, the hardness and impact toughness of the steel shot and steel sand should be comprehensively considered. That is to say, while having good hardness, the impact resistance of the steel shot and steel sand under a large amount of impact load mainly depends on the magnitude of the impact toughness. Under the condition of multiple impacts with low energy, the impact resistance mainly depends on the strength and plasticity of the steel shot and steel sand.
