Advantages and Disadvantages of Hot Working Process

Advantages and Disadvantages of Hot Working Process Points : Advantages and Disadvantages of Hot Working Process Advantages
  1. Mechanical properties for example ductility, toughness, percentage reduction in area, percentage elongation and resistance to shock and vibration are better due to the refinement of grains.
  2. The impurity similar to slag are squeeze into fibres and distributed all over the metal.
  3. The particle structure of metal is refined.
  4. The porosity of metal is mostly eliminating.
Disadvantages
  1. It generates poor surface finish, due to rapid oxidation and scale construction on metal surface.
  2. Due to poor surface finish, close tolerance cannot be maintain.
  3. It requires costly tools.
