Annealing heat treatment

Annealing 

ANNEALING was the first form of heat treatment applied to ferrous metals. It is essentially the softening of a base metal to make it more malleable. The process involves a controlled heating and slow cooling which induces softness. Additionally, the process removes gases, relieves stresses and enhances the mechanical properties in alloyed steels. This is generally performed at temperatures around 700-800 oC
