The purpose of normalizing isa)Grain structure refinementb)Removal of...
Normalizing: Heat the steel from 30°C to 50°C above its upper critical temp, held about fifteen minutes, and then allowed to cool down in still air. The homogeneous structure provides a higher yield point, ultimate tensile strength, and impact strength with lower ductility to steels.
Main objective
1. Refine grain size in metal, improve strength and hardness, reduce ductility
2. Remove cold worked stress.
3. Remove dislocations due to hot working.
