NEX™ rolls are composed of high alloy and high carbon centrifugally cast double poured outer shell with a nodular cast iron core. NEX™ provides excellent hardness, wear resistance, and high-temperature properties. The is particularly suitable for mills requiring the highest standards of surface finish and dimensional control where the exceptional wear resistance reduces the need for frequent roll changes, so enhancing mill productivity. The fine microstructure and high hardenability of this material mean that there is no fall-off in hardness to discard so ensuring consistently excellent performance throughout the life of the roll.
