The Difference between Annealing and Normalizing:
Annealing:
- Annealing process is used to improve the softness and ductility of on metals.
- The time taking is longer.
- This is a slow process due to the cooling is done in the furnace itself.
- The structure of grain is coarse.
- This type of treatment is more cost than normalizing.
- To improve the machinability it is used.
- For an annealed steel the quality of the machined surface is low.
- This type of steels are less harder than the normalized metals.
Normalizing:
- This process of normalizing is used to refine the grain structure.
- It takes less time.
- In this cooling, is done in the air itself.
- Structure of grain is finer.
- This treatment is less costly.
- It is used to improve the machinability.
- For this type of steel the high quality of the machined surface is done.
- This steel has harder than the Annealing.
