Advantages and disadvantages of hot working and cold working


Advantages and disadvantages of hot and cold working: In this article we will learn about Advantages and disadvantages of hot working and cold working. The detailed explanation about hot working and cold working Advantages and disadvantages is as follows:


Advantages of Hot Working:



  • The required shape can be done with less effort because it has less strength at high temperature.
  • Due to the hot working refinement of grains occur.
  • This type of process is less costly.
  • By this hot working process there is no strain hardening needed.
  • It can obtain fiber structure properties.
  • This process is used to may works.

Disadvantages of Hot Working:

  • This working conditions may form scaling and oxidations.
  • This process does not get a required surface finish.
  • External machining process is needed to finish the process.
  • Due to this high-temperature metal life gets reduced.
  • Hot working is not safe to handle.

Advantages of Cold Working:

  • Cold working is mostly used for bulk production.
  • This working condition can obtain a high surface finish.
  • This is more useful in the automation process.
  • High accuracy and the efficient product can obtain by this process.
  • Defects on work can be easily identified and removed in this process.

Disadvantages of Cold Working:

  • * Equipment is costly.
  • * External work is needed to reveal the internal stress.
  • * This process does not use to all metals only ductile material is used.
