Heavy Industry Forgings
Heavy industry forgings are key basic components that support the stable operation of modern industrial systems.

Compared with castings and ordinary machined parts, heavy industry forgings are formed through high-temperature and high-pressure forging processes, with denser internal structure, continuous metal fibers, and stronger resistance to impact, fatigue and high load.

They are widely used in energy power, metallurgical mining, shipbuilding, pressure vessels, rail transit and large machinery, and are regarded as the “hard core” of heavy equipment.

Features of Heavy Industry Forgings

  • High structural density

    Forging eliminates internal porosity and inclusions, providing excellent integrity for heavy-duty working conditions.

  • Superior mechanical properties

    High tensile strength, yield strength and impact toughness, able to withstand long-term heavy loads.

  • Continuous metal fiber flow

    The grain distribution matches the stress direction, greatly improving fatigue resistance and service life.

  • Stable dimensional performance

    Good rigidity and small deformation, suitable for large-scale key components.

  • Customizable performance

    Through different heat treatment processes, the required hardness, strength and toughness can be obtained.

  • Large shafts, transmission shafts, intermediate shafts
  • Turbine discs, generator rotors, wind power flanges
  • High-pressure vessel forgings, cylinder blocks
  • Ship stern shafts, rudder horns, marine flanges
  • Mill rolls, press columns, large gear blanks
