Is it better to forge steel balls or cast them?

Forging is a processing method that uses forging machinery to apply pressure to metal billets, causing them to undergo plastic deformation to obtain forgings with 

certain mechanical properties, shapes, and sizes. Casting involves melting metal, manufacturing molds, and pouring molten metal into the molds to solidify and obtain 

metal parts with certain shapes, sizes, and properties. Comparison of forming methods: Forging can improve the microstructure and mechanical properties of metals. 

After hot working deformation through forging method, the casting structure transforms from coarse dendrites and columnar grains to equiaxed recrystallized structures 

with finer and uniformly sized grains due to metal deformation and recrystallization. This compacts and welds the segregation, looseness, porosity, slag inclusions, etc. 

inside the steel ingot, making the structure more compact and improving the plasticity and mechanical properties of the metal. The mechanical properties of castings are 

lower than those of forgings of the same material. In addition, forging processing can ensure the continuity of the metal fiber structure, keeping the fiber structure of the 

forging consistent with the shape of the forging, and ensuring the integrity of the metal streamline, which can ensure that the parts have good mechanical properties and 

long service life. Precision forging, cold extrusion
