This heat treatment:

Reduces hardness and makes the metal easier to machine and form,
Relieves internal stresses accumulated during previous manufacturing processes,
Increases ductility and toughness,
Ensures uniform mechanical properties, and
Enhances the overall quality and performance of the end product.fractory+2

How Does Annealing Work?

The typical steps in a modern annealing cycle include:

Loading: Metal coils or components are loaded into the furnace, ensuring optimal spacing for uniform heat distribution.
Sealing: A protective cover (bell) is placed over the material to create a controlled, oxygen-free environment.
Heating: The furnace heats the metal to a predetermined temperature in the presence of protective gases (like nitrogen or hydrogen).
Soaking: The metal is held at temperature, allowing structural realignment at the atomic level.
Controlled Cooling: The temperature is brought down in a regulated manner to avoid distortion and ensure desired properties.
