Hot forging process is performed at extreme high temperatures (up to 1100°C for steel, 360°C to 520°C for Al-alloys, 700°C to 800°C for Cu-alloys). These temperatures are necessary to avoid strain hardening of the metal during deformation.


  • It offers Good ductility.
  • more flexible than cold forging, thus customized parts can be manufactured and excellent surface finish.


  • Less precise dimensional tolerance.
  • Cooling process must be carefully monitored.
  • Risk of wrapage.
  • Risk of reaction of job from atmosphere.
