Chemical composition is the most basic indicator of steel shot and steel grit. It will determine the microstructure of steel shot and steel grit and the effect of subsequent heat treatment. Carbon (C) determines the hardness and quality of the steel shot. The content should be moderate. If the carbon content is low, the hardness will not be enough and the effect will not be achieved. If the carbon content is high, the hardness will be too high and the steel shot will break easily. Silicon (Si) can significantly increase the elastic limit, yield point and tensile strength of steel. Manganese (Mn) can increase the strength and hardness of steel shots and improve the hot working performance of steel. Manganese can also reduce the harm of sulfur and improve Wear resistance of steel shot. Sulfur (S) and phosphorus (P) are harmful elements that can easily make steel shots brittle and lead to premature rupture. They should be as low as possible (<0.05% is optimal).
