    | Product Description

    Forged round bars are high-strength cylindrical steel products manufactured through open-die or closed-die forging processes. After heat treatment and rough/precision machining, they provide excellent mechanical properties and reliability. Compared with rolled round bars, forged round bars feature a denser internal structure, superior fatigue resistance, and higher impact strength. They are widely used in automotive manufacturing, mining machinery, oil & gas, energy equipment, mold making, and heavy machinery industries.
