The technical and mechanical characteristics of steel balls are high hardness, sphericity, size according to standards and mechanical and metallographic characteristics according to standards, such as high resistance to wear and deformation.

Hardened forged steel balls are ideal for ball mills when extreme wear and chemical resistance are required. Also, these pellets can be used when generating heat is decisive for the grinding and dispersion processes. Due to its high relative density and hardness, alloy steel has special uses in stone crushers and mixing hard and heavy materials. Also, these types of steels are used in Asia where strong pressures and blows are applied or in various stone crushing processes. Forged steel balls offer many advantages in particle size reduction and fine dispersion of high viscosity fluids.

The advantages of rolled-forged bullets can be listed as follows:

Using the rolling-forging process makes the bullet have a smooth surface and is free of any surface defects, deformation and distortion. These characteristics increase the efficiency of crushing and homogenization in Asia.
The rolling-forging process can remove the internal defects in the steel structure (caused by billeting) and improve the microstructure. This process makes the mechanical properties of the produced bullet higher than other bullets.
Rolling-forge bullets have a higher density than other bullets, and this causes the failure rate of these bullets to be lower than others, which, as a result, reduces the consumption of bullets and energy in Asia.
Bullets produced by the rolling-forge method have a constant quality and have higher fracture toughness and hardness, and their internal and external structures are slightly different from each other.
Steel balls have all the advantages of steel. Heat treatment, high production efficiency, mechanized and automatic process in the production of pellets, production steps without the need of manual work and interfering factors are among its other strengths.
