The commonly used materials and applications of rolls are listed in the table. The performance and quality of rolls are generally determined by their chemical composition and manufacturing process. They can be assessed based on their microstructure, physical and mechanical properties, and the type of residual stresses present within the roll (see Roll Inspection). The effectiveness of rolls in a rolling mill depends not only on their material and metallurgical quality but also on usage conditions, roll design, and maintenance.
