High-carbon steel shot is a type of shot-blasting grit that is made of high-carbon steel. It is a hard and durable abrasive that is commonly used in shot-blasting applications to clean, deburr, and prepare surfaces for coating or painting. High-carbon steel shot is known for its long life, low dust generation, and ability to produce a uniform finish.

High-carbon steel shot is produced by melting high-carbon steel scrap in an electric furnace and then atomizing the molten metal into small, round pellets. The pellets are then heat-treated to increase their hardness and durability. The resulting high-carbon steel shot has a hardness of around 40 to 50 HRC (Rockwell hardness scale) and is available in various sizes ranging from S-70 to S-780.

High-carbon steel shot is commonly used in the automotive and aerospace industries, as well as in the fabrication of steel structures and components. It is also used to clean and prepare surfaces in the shipbuilding, foundry, and construction industries.

One of the main advantages of high-carbon steel shot is its long life. It can be reused multiple times without losing its effectiveness, which makes it a cost-effective abrasive option. Additionally, high-carbon steel shot produces very little dust, which makes it a safer and more environmentally friendly abrasive option compared to other types of abrasives.

High-carbon steel shot is also known for its ability to produce a uniform finish on surfaces. The round shape of the pellets allows them to impact the surface evenly, which results in a consistent and uniform finish. This makes high-carbon steel shot ideal for applications where a uniform finish is required, such as in the preparation of surfaces for painting or coating.

However, high-carbon steel shot does have some limitations. It is not suitable for use on soft or delicate surfaces, as it can cause damage. Additionally, high-carbon steel shot may not be suitable for use in applications where a very fine or smooth finish is required, as it can leave a slightly rough surface.

Overall, high-carbon steel shot is a durable and versatile abrasive that is suitable for a wide range of shot-blasting applications. Its long life, low dust generation, and ability to produce a uniform finish make it a popular choice among professionals in various industries.
