Heat Treatment - Annealing

Annealing is the process for softening materials or to bring about required changes in properties, such as machinability, mechanical or electrical properties, or dimensional stability. The annealing process consists of heating the steel to or near the critical temperature (temperature at which crystalline phase change occurs) to make it suitable for fabrication.

Annealing is performed to soften steel after cold rolling, before surface coating and rolling, after drawing wired rod or cold drawing seamless tube. Stainless steels and high alloy steels generally require annealing because these steels are more resistant to rolling.A material can be annealed by heating it to a specific temperature and then letting the material slowly cool to room temperature in an oven. This process is expensive because the oven is unusable during the cool down process.
