Introduce:
Cold rolling is a forming process which takes place below recrystallization temperature. It involves further reduction of already hot-rolled strip and a determining of the mechanical and technological properties of the same strip. Due to specific requirements during processing, cold rolling isregarded as a speciality within the diverse application areas of cold-work tool steels. They nevertheless have uses in other fields such as back-up rolls, straightening and section-bending rolls.
