Hot Forging

What is Hot Forging?

Hot Forging is a metalworking process that involves heating metal materials above their recrystallization temperature (typically 50%-70% of the material's melting point, i.e., a high-temperature state above the recrystallization point) to increase ductility, making it easier to deform into complex shapes under external force. This process employs forging equipment (such as hammers or presses) to apply pressure to heated metal billets, inducing plastic deformation. This not only forms components with desired shapes and dimensions but also significantly improves the mechanical properties of forgings by refining the metal grain structure, increasing material density, and enhancing impact resistance, thereby producing stronger, more durable parts. Hot forging is commonly employed in manufacturing high-strength components for industries like automotive, often utilizing methods such as hammering or pressing. It is frequently followed by heat treatment processes to further optimize performance.
