Low Carbon Steel Shots

Low Carbon Steel Shots are created using low-carbon scrap that has been carefully selected and contains little sulfur and phosphorus. Scrap is melted in induction furnaces at 1600-1650 °C, cooled in water after atomization, and has a bainite microstructure during manufacturing. Crack-free grains of low-carbon steel shots particle are obtained like stainless steel shot. Furthermore, no heat treatment is used.

Low carbon steel shot exhibits excellent performance in rust, oxide, and sand removal processes, deburring, surface preparation, and shot peening operations with portable shot blasting machine due to their long service life and high hardness. Low carbon steel shot and stainless steel shot can be used in foundries, steel mills, forging and rolling mills, shot blasting machine, the steel industry, structural steel, automotive, ship, and aircraft applications. High carbon steel shot, on the other hand, has a martensitic microstructure that is hard and brittle because it is made of various types of scrap, and heat treatment after casting results in surface cracks. 

Low Carbon Steel Shots made of low carbon and high manganese steel have a high capacity to withstand impacts, which are dispersed evenly throughout the steel shot. Low carbon steel shots and stainless steel shot are peeled down into thin layers during shot blasting operations, resembling the layers of an onion, for up to 80% of their life due to wear, and are only broken into small pieces due to material fatigue. Due to their division into smaller and less significant parts, sand blasting machine and blade erosion are also significantly decreased.

Chemical Properties of Low Carbon Steel Shots

• Carbon: 0.10% - 0.15%

• Manganese: 1.20% - 1.50%

• Silica: 0.10% - 0.25%

• Sulfur: max. 0.035%

• Phosphor: max. 0.035% 

Advantage Of Low Carbon Steel Shots

Here are some advantages of low carbon Steel Shots:

• Low carbon steel shots have an isothermal transition (bainite) structure, which provides strong impact resistance and consistent performance.

• To ensure the hardness of steel shots, low carbon steel shots are made from high quality, low carbon, low residue, low phosphorus, and low sulfur scrap steel.

• Due to its structure and high toughness, low carbon steel shots are difficult to break; the number of repeated cycles reached about 3600 times, and consumption decreased by more than 20% in comparison to other shots.

• The low carbon steel shots always remain round, resulting in a smooth collision between the shot blasting machine and the steel shots.

• At least 20% of the dust emissions will be reduced because low carbon steel shot will only be shrunk down to the size of a thin peel.

Production of Low Carbon Steel Shots

The specific steps are:

• Raw Material: The most common raw material is steel scraps. The market for steel shot is primarily impacted by the price of scrap steel.
• Melting: In this step, steel scraps turn into steel liquid.
• Atomizing: By means of centrifugal force, the molten steel liquid is propelled from the rotary wheel and dropped into the cooling medium, where it cools and is then used to form cast steel shots.
• First-Round Sieving: In preparation for the fine sieving later, the steel shots are sorted into rough categories based on their diameters.
• Refining Shape: The refining machine determines how round the finished product is.
• Secondary Quenching: Change the metallographic makeup of steel shots and make steel abrasives harder.
• Low Backfire: Increase the steel abrasives' durability and steel shots' toughness.
• Second-Round Sieving: Following this step, steel shots will be strictly categorized into distinct grain sizes (from Steel Shot S70 to S780).
• Quality Check: The typical quality inspection process involves testing chemical composition and physical characteristics, such as density, size distribution, structure, and hardness.
• Packaging And Storage: Packaging in 25 kg, 50 kg, & 1 ton and Maintaining the steel shot in a dry, cool warehouse.
