Its primary goal is to reduce hardness and relieve internal stresses in the material, thereby improving ductility and toughness.During annealing, the material is heated below its melting point, allowing for the rearrangement of its internal structure. This temperature increase facilitates the movement of atoms, enabling the redistribution of dislocations and the elimination of defects like grain boundaries and vacancies. Consequently, internal stresses are relieved, leading to a decrease in hardness.

                                                                                  Quenching and Tempering: Increases hardness and strength in martensitic stainless steels.Enhances resistance to corrosion and wear, making it ideal for applications in harsh environments.

As the steel undergoes high-temperature rolling, its internal structure undergoes significant transformations. At these elevated temperatures, the steel becomes more malleable, allowing for greater deformation without fracturing. This plastic deformation facilitates the alignment of the steel’s crystalline structure, resulting in improved grain structure and grain boundary diffusion. Consequently, the steel’s dislocations are reduced, leading to enhanced strength properties such as tensile strength, yield strength, and hardness. Additionally, the rapid cooling that follows the hot rolling process helps to “freeze” these favorable microstructural changes in place, further contributing to the overall strength enhancement of the steel.
