Three types of work rolls for cold strip mills are currently available on Villares Rolls portfolio.

The main difference between these is the chromium content in their chemical composition. To define a product specification it is necessary to analyze the rolling process characteristics and the value given by the user to the performance requirements (i.e. mechanical resistance and wear resistance).

These requirements are usually conflicting with each other in the rolling process perspective. For rolling mills with high stability (meaning low accident rates), it is recommended to use products with 5%Cr. On the other hand, if the accident rate is high, it is recommended to use products with 3%Cr
