Low-carbon steel shot, also known simply as low carbon steel shot, is a type of steel shot characterized by its extremely low carbon content, typically less than 0.2%. This unique composition, combined with the presence of elements like silicon (Si) and manganese (Mn), contributes to its superior fatigue resistance compared to high-carbon steel shot.

During the production process, a low-carbon stable internal structure is achieved through deoxidation, resulting in excellent toughness, hardness, and rebound effect. The raw materials used to make low-carbon steel shot include low-carbon high-silicon steel and low-carbon steel plate, often supplemented with additional alloys like manganese iron, silicon iron, and chromium iron.

While the overall production process of low-carbon steel shot shares similarities with that of high-carbon steel shot, there are notable differences in the details. The process begins with steelmaking, followed by tempering and centrifugal casting to form the shot. Once the shot is made, it undergoes drying, sieving, quenching to enhance hardness, surface treatment, further heat treatment and tempering for improved performance, and finally, subdivision.

Low-carbon steel shot is highly versatile and finds widespread application in various industries. It is primarily used for shot blasting precision castings, springs, gears, and for the pretreatment of steel plates in steel plants. Despite its higher initial cost compared to high-carbon steel shot, low-carbon steel shot's exceptional durability and longevity make it a cost-effective choice. High-carbon steel shot is prone to breaking during shot blasting, whereas low-carbon steel shot rarely experiences such failures, ensuring a longer service life and overall better value for money.
