The Indefinite Chilled Double Poured Roll Was developed by careful selection and adjustment of the alloying elements and subsequent heat treatment cycles to control and distribute the morphology of the graphite and the basic matrix of the roll to obtain a range of microstructures varying from a Bainitic-Martensitic matrix to a Martensitic-Bainitic matrix depending on the end use conditions in order to get the best performance. The presence of ternary and complex primary carbides in the working layers ensuring a good and uniform roll wear property.

Indefinite Chilled double poured Rolls are generally used in the last two to three stands (F4, F5 and F6 Stands) in the Finishing Stands of Hot Strip Mills as well as in Roughing & Finishing Stands of Four High Plate Mills and Finishing Stands of Rod & Narrow Strip Mills
