Forged Ball Details:
Forged steel balls are made by heating the metal to a suitable temperature, applying pressure to the metal blank by forging, causing it to undergo plastic deformation to obtain steel balls with certain mechanical properties, shapes and sizes. This process can eliminate defects such as loose casting produced during the smelting process, optimize the microstructure, and preserve the complete metal flow line, so that the mechanical properties of the forging are better than those of the castings of the same material.

Casting Ball
Casting steel balls are made by melting scrap steel, scrap iron and other waste furnace materials using a medium frequency electric furnace, and adding appropriate amounts of precious metal alloys (such as ferrochrome, ferromanganese, ferrovanadium, etc.) during the melting process for chemical composition quenching and tempering. When the molten iron temperature reaches above 1550℃ and meets the process requirements, the qualified molten iron is poured into the steel ball mold, and the spherical iron alloy wear-resistant body is made through quenching, tempering, testing and packaging processes.
