Steel shot is a commonly used abrasive in various industries for surface preparation and shot peening. It is made through a complex manufacturing process that involves melting, atomizing, and heat treatment. we are the leading steel shot manufacturer in India. In this article, we will provide an overview of the manufacturing process of steel shots.
Introduction to Steel Shots
Steel shots are small spherical particles of steel that are used in a variety of applications such as surface preparation, cleaning, and shot peening. They are produced through a rigorous manufacturing process that involves melting steel and converting it into small, uniform-sized particles. Steel shots are preferred over other abrasives due to their high durability, consistent size and shape, and ability to recycle.
Manufacturing Process of Steel Shots
The manufacturing process of steel shots involves four main stages: melting, atomizing, heat treatment, and screening.
Melting Stage
The first stage of the manufacturing process is melting. High-quality steel scrap is loaded into a furnace and melted to a liquid state. The steel is heated to temperatures above 1,600 degrees Celsius to ensure that impurities are eliminated, and a consistent alloy is produced.

Atomizing Stage
The molten steel is then poured through a nozzle and atomized into small droplets. This is accomplished using high-pressure water jets or compressed air, which break up the molten steel into droplets ranging in size from a few microns to a few millimeters.
Heat Treatment Stage
The third stage of the manufacturing process is heat treatment. The steel droplets are then hardened and tempered through a controlled heat treatment process. This process involves heating the steel droplets to a specific temperature and holding them at that temperature for a specific duration. The steel droplets are then rapidly cooled to harden them.
Screening Stage
The final stage of the manufacturing process is screening. The hardened steel droplets are screened to separate them into different sizes. The steel shots in India are then classified into different size ranges, packaged, and sent to the market.

Advantages of Steel Shots
Steel shots have many advantages over other abrasives. Some of these advantages include:
- Durability: Steel shots are highly durable, which means they can be reused many times before they need to be replaced.
- Consistent size and shape: Round Steel shots are spherical and have a consistent size and shape, which ensures that the surface finish is consistent and predictable.
- Recyclability: Steel shots can be recycled many times, which reduces waste and lowers costs.
- High blasting efficiency: Steel shots have high blasting efficiency, which means they can remove coatings and other materials from surfaces quickly and effectively.
Applications of Steel Shots
Steel shots are used in various applications, such as:
- Surface preparation: Fine Steel shots are used to prepare surfaces for painting, coating, or bonding. They are used to remove rust, paint, and other coatings from metal surfaces.
- Shot peening: Steel shots are used in shot peening applications to improve the fatigue life of metal components. Shot peening is a process that involves bombarding metal surfaces with steel shots, which induces compressive stresses and improves the fatigue life of the metal.
- Cleaning: Steel shots are used to clean metal surfaces, such as castings and forgings, to remove scale, dirt, and other contaminants.
- Deburring: Steel shots are used to remove burrs from metal surfaces, which improves the quality of the product.
Conclusion
In conclusion, steel shots are manufactured through a complex process that involves melting, atomizing, heat treatment, and screening. Steel shots have many advantages over other abrasives, including durability, consistent size and shape, recyclability, and high blasting efficiency. Steel shots are used in various applications such as surface preparation, shot peening, etc.
